anything that wasn't already in /var/log/messages, /var/log/mail etc.
Seems like a duplication of effort and a waste of space in
/var/log/journal. (which afaict can just be deleted).
It is significantly more powerful than traditional logging:
For example
journalctl /usr/bin/foo --> get messages from program foo
journalctl /dev/sda --> hard-drive problems ?
journalctl -p error --> only errors
Currently it is not a full replacement for syslog but
I suggest you to
check it out.

Just a matter of building journalctl from source I'd imagine, as would
be the case if you were missing grep.
I happen to agree that the binary format is unnecessary, but it also
happens to be a discretionary power of the author, and as soon as
there's a working and ubiquitous "journalctl" to parse it... and its
accompanying documentations... complaining will only start flame wars.

It's also full of FUD about supposed limitations of syslog since
it conveniently leaves out the advancements of modern syslog
implementations like rsyslog or syslog-ng which are mostly on-par
or superior in terms of features and functionality (well execept
the log sealing feature but that seems inherently racy and is
probably useless to those settings where log integrity is
important). I haven't seen any hard evidence of higher
performance of the "journal" compared to those syslog
implementations. So the "journal's" raison d'être pretty much
boild down to NIH.
BTW, tha fact that you can't turn this completely useless stuff
off is an execellent example of what is wrong with the new world
order you're buying in when switching to systemd (rather than
nebulous feeleings people have expressed here or the fact that
the boot process and ui differ from sysvinit).

I need to redo all of system log filtering by filtering some arcane, non-unix

Sorry, that's not a unix utility. That needs to be fixed.
Can't it send it's messages to a pipe in text and any one of several log
deamons that have been developed over the years to hand logs, do their job?
Or are you saying this tool doesn't play nice with with existing linux tools
and tell everyone to "get a life and learn the window-ms way"?
Yeah -- I can dump a winlog in XML, -- it's a pain in the *** to parse.
I had to write a special perl prog just to count up error occurrences of
a program... on linux, it would have been a grep|wc.
I assume of course -- that the log entries will also stll hold to the unix
of 1-2 lines/message 1 if it can possibly do it (even overly long)??
I'm feeling a bit nervous about this -- like I'm gonna spend the next 5-7 years
learning a new windows-like interface -- with a service manager to control boot and
a binary log with awful filtering abilities...
That isn't unix/linux... MS has been trying to tell linux that their way is the
way of
the future for a long time... is this another way for them to get in the backdoor?

Yes it can, in a wide variety of ways.

That's probably not the 'standard user profile', but surely a valid
point; and as Peter pointed out often yet, syslog remains compatible
with systemd.
"zypper dup" might need to find a reasonable way of identifying if
you're a 'standard user' or 'advanced user': the pure presence of
/var/log/messages and/or syslog packages does not indicate anything
here (as all existing users have those... but only a fraction of "all
users" have setups as described by you).

That's fine for you but there are a log of
monitoring and security
robots which are configured to watch /var/log/messages. Many users
have advanced syslog setups running, so please don't remove syslog
at least in "zypper dup" case.
That's probably not the 'standard user profile', but surely a valid
point; and as Peter pointed out often yet, syslog remains compatible
with systemd.
"zypper dup" might need to find a reasonable way of identifying if
you're a 'standard user' or 'advanced user': the pure presence of
/var/log/messages and/or syslog packages does not indicate anything
here (as all existing users have those... but only a fraction of "all
users" have setups as described by you).

So, if you update, you'll keep syslog. If you do a new install, you
won't get it but can install it in addition...

Not having /var/log/messages does not "break" anything, does it?
I can perfectly remove that file and my system keeps on running.

How about waiting for systemd 190 to land in Factory (probably next

have in 12.2) ?

Wait for systemd 189 (or later) + kernel 3.5 (or later), they will
support kernel structured logging in the journal.

Well.... because that's a lame answer not worth considering.
I'm an administrator and lead developer on a few projects, and I can
tell you, I don't work to increase the amount of disk usage on
SourceForge or to cater to the needs of a very few people I like...
the more my project's used, the better I feel. In essence, opensource
projects strive, usually, to be useful for as many as possible and
manageable.
So you can't tell me "nobody's forcing you to use this distro",
because... well... this distro isn't being maintained so that only OBS
can use it. It's for *general* use, and it has to cater to *general*
needs and public.
Last I checked, openSUSE was good for both, desktop, laptop and
server. If you want to drop some of those explicitly, that would have
to be announced. It hasn't, or at least I didn't see the announcement.
Right now, in this particular point, we're talking about server
(sysadmins tend to manage servers, but that's not always true).

Hello,
Before we all end up in flames, a hopefully not too biased view from
syslog-ng upstream :-)
First of all, systemd journal is a perfect solution for about 90%+ of
openSUSE users, which have stand alone workstations and don't care at
all about logging. They don't need rsyslog or syslog-ng. The journal
collects logs under /var/log/journal into some binary files. By default
it does not take more than 5% of available disk space, so logs can't
fill up the partition accidentally. It's very limited, but user friendly.
Actually I don't really understand, why syslog is still installed on
openSUSE (ArchLinux removed syslog from systemd based installations to
avoid dual logging...), but this is a different questions...
For the remaining <10%, see some information below.

The good news is, that standard
syslog setup is supported. One can
almost completely get rid of systemd journal. Just "rm -fr
/var/log/journal". It's safe, systemd journal will still keep enough
information in tmpfs to provide information about running services. It
still takes over /dev/log, but forwards all information to
/var/run/systemd/journal/syslog so syslog-ng can read local logs from
there instead of /dev/log.
The bad news is, that this info is not mentioned in any man pages
installed on openSUSE.
So, if you still want a flexible logging solution, like syslog-ng, on a
server, or a networked workstation, just do that "rm -fr
/var/log/journal". This way even that 5% of the partition is not wasted,
and you can configure your favorite logger to your liking. You will have
all the usual formatting templates, networking possibilities, filters,
patterndb, etc.
I hope this helps, and flames are extinguished :)

Strangely enough, I agree. I complain about the binary log because
it's unnecessary complexity and obscurity, but the fact that
workstation users rarely need to bother reading the logs kind of
dilutes the effects of all that, and the fact that syslog is still
functional in openSUSE is a very very good thing for those that do.
Having it run, by default, in tandem with journal was, AFAIK, a
transitional measure. Because all init stuff goes into the journal,
and users new to systemd won't know where to find all those messages
and be unable to fix boot problems. Now, systemd is fixing the tty
"bug" that made it not show those messages to the console, meaning
users will *see* what's wrong, and syslog will cease to be useful in
the default installation.

logs can't fill up the partition accidentally. It's very limited,
but
user friendly. Actually I don't really understand, why syslog is
still installed on openSUSE (ArchLinux removed syslog from systemd
based installations to avoid dual logging...), but this is a
different questions...
Thanks Peter for the info. So, let's remove syslog/rsyslog from the
default install now.
Coolo, could you do the change - if you agree with it, please?

And we can have both working together? If so, there's no real harm :) Guido,
I'm not an expert in this, but I have one question and this is a one
time intervention... Can journald perform remote logs? That's all I
need.
If you're talking about forwarding via TCP/UDP, then no, you
need a capable syslog implementation for that.

Ok, then how you implement all those features mentioned in the design
document to work fast ? Simplicity: little code with few dependencies and
minimal waste through abstraction.
Text files are as simple as it gets.
Zero Maintenance: logging is crucial functionality
to debug and monitor systems, as such it should not be a problem source of its own, and
work as well as it can even in dire circumstances. For example, that means the system
needs to react gracefully to problems such as limited disk space or /var not being
available, and avoid triggering disk space problems on its own (e.g. by implementing
journal file rotation right in the daemon at the time a journal file is extended).
Nothing to do with text files or not, it's an implementation issue.
Robustness: data files generated by the journal
should be directly accessible to administrators and be useful when copied to different
hosts with tools like “scp” or “rsync”. Incomplete copies should be processed gracefully.
Journal file browsing clients should work without the journal daemon being around.
Text files provide this natively
Portable: journal files should be usable across
the full range of Linux systems, regardless which CPU or endianess is used. Journal files
generated on an embedded ARM system should be viewable on an x86 desktop, as if it had
been generated locally.
ASCII text is the epitome of portability. Use UTF-8 if you need
unicode support. In any case, highly portable.
Performance: journal operations for appending and
browsing should be fast in terms of complexity. O(log n) or better is highly advisable, in
order to provide for organization-wide log monitoring with good performance
Appending is O(1) (assuming constant line length) on text files. If
browsing means reading the first, second, third etc entries sorted by
time, then browsing is also O(1) in text files. If browsing means
reading the entry at time X (for arbitrary time X), then it's O(log n)
in text files by means of bisection, as text-based logs are naturally
sorted by timestamp.
If you need to search by other fields, you need indices. This can be
done with text files, but syslog-ng already supports a better way:
just dump everything into a (pattern) database as it comes. In any
case, if you introduce indices, appending is no longer O(1).
Integration: the journal should be closely
integrated with the rest of the system, so that logging is so basic for a service, that it
would need to opt-out of it in order to avoid it. Logging is a core responsibility for a
service manager, and it should be integrated with it reflecting that.
Again, has nothing to do with text or not.
Minimal Footprint: journal data files should be
small in disk size, especially in the light that the amount of data generated might be
substantially bigger than on classic syslog.
While text files have a tendency to include some bloat, both because
of the format and because of the verbose nature of human-readable
messages, data compression can easily compensate those redundancies,
and it has been the mainstream for logging for ages. The fact that
compression happens at log rotation does not detract from its
effectiveness, and some compression schemes are even random-readable
(think bzip2). Other compression schemes are packetizable (deflate),
making them suitable for record-by-record on-the-fly compression.
Compressed formats are technically binary, but in practice, due to the
ubiquity and transparency of decompression tools, rather equivalent to
text files. You can even zless and zgrep.
General Purpose Event Storage: the journal should
be useful to store any kind of journal entry, regardless of its format, its meta data or
size.
Text files can contain arbitrary data, so there's nothing more
general-purpose than text files. If you need binary blobs, you have
various codings that will result in ASCII-safe text representing it.
Just to mention two, hex and base-64.
Unification: the numerous different logging
technologies should be unified so that all loggable events end up in the same data store,
so that global context of the journal entries is stored and available later. e.g. a
firmware entry is often followed by a kernel entry, and ultimately a userspace entry. It
is key that the relation between the three is not lost when stored on disk.
Base for Higher Level Tools: the journal should provide a generally useful API which
can be used by health monitors, recovery tools, crash report generators and other higher
level tools to access the logged journal data.
Universality: as a basic building block of the OS the journal should be universal
enough and extensible to cater for application-specific needs. The format needs to be
extensible, and APIs need to be available.
Clustering & Network: Today computers seldom work in isolation. It is crucial
that logging caters for that and journal files and utilities are from the ground on
developed to support big multi-host installations.
Unrelated to store format. "Data store" here can easily be a series of
text files.
Scalability: the same way as Linux scales from
embedded machines to super computers and clusters, the journal should scale, too. Logging
is key when developing embedded devices, and also essential at the other end of the
spectrum, for maintaining clusters. The journal needs to focus on generalizing the common
use patterns while catering for the specific differences, and staying minimal in
footprint.
Again, no reason why text files can't scale. There's no need to stuff
everything into a single text file, and abstraction APIs can easily
query several text files in tandem. Text-vs-binary provides no
features in this regard.
Security: Journal files should be authenticated to
make undetected manipulation impossible.
Text-based log lines can also be authenticated.You have MACs, PGP
ASCII armor, etc...
Even assuming MACs on both implementations, I seriously doubt journal
files are safer from tampering by root, though, leaving it in the same
situation as syslog is. If root can create a log file, root can tamper
with it.

That's probably the reason why no other distro has chosen to rely
on it exclusively (not even Fedora!), so the oS userbase doing

that users who rely on logs (and/or have significant amounts of
log messages) should install rsyslog.

Hay, I am in danger of doing a Linus here ... As he so often says "the

break users, (b) fail to test properly, themselves, (c) Passively
accept the latest crap.
If they do accept crap they reinforce the vicious circle of Projects
shipping barely alpha code as 'finished'. It tool me minutes to
conclude Kmail2 was a stinking pile of manure, a day to decide that
regressing to Kmail1 would be unnecessarily difficult and a morning to
get Claws Mail working, including fixing Mdir mailboxes.
The next time I will dump all KDE.

Don't understand me wrong -- I think systemd has a lot of good
ideas and a sound concept. The introduction in oS was too rushed,
and its tendency to subsume all other system service are
frightening from a sysadmin maintenance perspective.
I've read your joke yesterday about CUPS not being subsumed by
systemd right yet -- but I wouldn't hold my breath for it. crond is
next [*], what comes afterwards? Are you sure that printers are not
something that might appear and disappear and thus something that
systemd developers might want to start to their we-control-it list?
Since, that's the pattern -- ``everything that might come up or go
down asynchronously has to be managed by systemd'' (TM).
For developer's laptops, that's nice, but on servers the current
state of affair is not adequate.
Joachim
[*] Note: My problem ain't because systemd is not able to issue
time-event based activations. It's clear that it is. It's because
cron is already completely inadequate for any professional job
scheduling tasks -- and systemd is worse, instead of being better.
The actual problem is decoupling: substitution of cron jobs in a
given distribution seems to be easier than decoupling from the
integration that's planned for systemd as a cron replacement. Well,
we'll see how that turns out;

No, again you did not understood what I said. (I am expressing myself
bad maybe?) what I said was that there will be no wrapper or otherwise
an intervention in cron or the at daemon in the systemd side at all.
people will be able to run cron or at without any change whatsoever.
But we may migrate the cron scripts shipped with the distribution to
native systemd timers (at some point in the future) and thus making cron
unnecessary as a default component.
what comes afterwards?
Here is the list http://cgit.freedesktop.org/systemd/systemd/tree/TODO
of things that come in the systemd side, there is no intention of
replacing any other major component.(apart from getting the DBUS
protocol support in the kernel and making systemd use it to drop the
circular dependency between dbus and systemd, Greg KH is working on
that, so I am confident it will go OK)

All the proposed goodness of the journal is totally useless if you

If I have a few bytes of garbage in a journal file, it is toast. With
the default of one file being 256MB in size (my root partition is 20GB),
this will amount to > 3 months of logs lost.
With traditional logging, a few bytes of garbage in the logfile will be
exactly that: a few bytes of garbage. Nobody will care. I can still
extract everything.
It is the old problem of data protection vs. data security. The data in
the journal is well protected. Protected from getting used by me.

Nobody will care only if log presence is important only to troubleshoot

that someone else fiddled with logs, which is not a good sign.
I looked for more debugging information in journal (12.2), so when I
stumbled over missing entries before certain time, I spent some time
looking at the system using Live USB. Why? Because I wasn't sure what
happened. Problem with logging can be a bug (which is harmless), or
sign that somebody cracked the system.
I found out that journal had 2 log files covering all the time from
installation to present, but it was ignoring presence of older file and
nothing will tell me that there is another log. This is probably yet
another not implemented functionality, at least in 12.2.
What is annoying from my prospective is that almost everyone is
learning systemd and journal and udev (and hopefully nothing more),
and availability of user to user help is sparse at best. When you are
stuck with a problem, you are on your own most of the time, which
grants days of fun, for those that have no other ways to have it.
When you have problem with 12.2, which has older version of systemd and
journald, you are on your own as those that know the best (Frederic
and Cristian) have very little interest to help with stuff that is
solved in a newer version, and on the other side, there is no new
systemd port to 12.2. Frederic mentioned that changes are too intrusive
to create port, which tells me that two systemd versions are not
backwards compatible and he will have to spend too much time
redesigning 12.2.
While I like to solve technical puzzles, amount that is now pushed on
users like me is overwhelming and I look for other areas that need
help to contribute to openSUSE for time being, ie. until number
of changes in certain time frame subside.

This was fixed in systemd 201 and backported to 12.3
which tells me that two systemd versions are not
backwards compatible and he will have to spend too much time

It is not backward compatible in the same sense kernel 3.0 is not source
compatible with 3.9, backward compatibility is there for the interfaces
that are exposed to the user or callers, not internal ones on which all
SUSE specific additions depend on.

Regardless, w/text logs there is nothing preventing you from recovering

of how easy it is for a hacker to cover their tracks -- just a
few bytes in the log and it is corrupt and can't be recovered.
You think that is better?
There are no benefits of binary logs to system owners, but

With traditional logging, a few bytes of garbage
in the logfile will
be exactly that: a few bytes of garbage. Nobody will care. I can still
extract everything.
Nobody will care only if log presence is important only to troubleshoot
technical problems, but usually it will raise a flag about possibility
that someone else fiddled with logs,

How can such untested alpha quality stuff make it into a distro?
Because the community didn't object when it was merged, or during the

Systemd's implementation is fragile too. Mapping files into memory

Maybe it's only the runtime log the one mapped, but still that's

Syslog also has a buffer, if you system crashes, that's it, you are done.

It is quite clear that you don't get how the system actually works and

No, storage systems don't work like that when you're mapping.
Don't think I don't understand how the system works, because I've read
the source. I've written patches for postgres (not upstreamed yet), so
I kinda know a little bit about this stuff. Let me tell you.
When you mmap files, you tell the kernel's page cache to do all I/O
for you. That's fast, because you've got a zero-copy environment like
that. But it's also quite out of your control how writes happen in the
end. When you write to a mapped memory location, you make that page
dirty. The kernel will flush it whenever it thinks it's necessary, in
no particular order.
Pages you dirtied 30 minutes ago can still be unwritten when a page
that has been written 1 second ago is flushed, because somehow the
kernel thinks that old page is hot and so won't flush it unless it's
told to. You tell it to with msync. Systemd just started using msync
for this very reason.
But msync flushes everything. And, again, in no particular order. If
there's a crash, or a power outage, you don't know which pages have
been written and which haven't. Postgres and most reasonably reliable
databases you mention will have a WAL to make sure pages are written
in the right order, and no torn pages appear. The WAL is a file opened
in sync I/O mode. It's slow, but safe. And it's not too slow since
it's append-only, which lets the operating system optimize sync I/O
quite a bit.
In append-only mode, you can have only one torn page: the last one. So
WAL entries are checksummed, and when WAL is replayed, you know
everything up to the first bad checksum is OK. You cannot do that with
memory mapped I/O, you have no way to force a specific write order.
So you're left with a system that will work most of the time, when the
thing crashing isn't the I/O. But if somehow I/O is interrupted (say a
bad interface, a kernel crash, a power outage), the binary format will
be messed with little hope of repair. Torn pages will have old info
interspersed with new info. Not all dirty pages will have been
written, and you have no way to know. If you implemented some kind of
page time-stamping, you'd have to be careful to match page size to
sector size, and assuming you get that right, you'd loose a lot more
info than you would if you hadn't mapped, because you'll have to
discard all valid pages after the first corrupted stamp.
So, memory mapped I/O is wrong if you need reliability. It's great
read-only, but that's about it.

mmap makes sense for readonly (e.g. libs), or read

And the binary format does not help any,
checksums can be added to text formats, and

Not only that. msync only flushes to the file system, but there is no
guarantee it will reach the disc. Ie: it flushes dirty pages, but
doesn't execute a write barrier. If you map an O_DIRECT file
descriptor with msync, the performance is abysmal under heavy writes.
Or was last time I tried.
So, LDAP's technique doesn't scale for write-heavy workloads. I will
certainly read the papers though...

Please use the names right, otherwise you will create another stupid

ZENWorks was forced in because of business reasons from the main

My gripes are more with systemd upstream and the mindset there (and of
course it is a good question to blindly follow an upstream, no matter
how stupid it might be, but that is a different question).
About "those who are doing the work decide": the problem is, that now
the ones trying to keep sysvinit alive are actively combatted by the
systemd proponents by removing all the init scripts so that they have to
fork the whole distribution and not just maintain a single package.

Well, after spending some time on making 12.3 work again, I must say
that removing the init scripts isn't the real problem. Neither is
dropping whole packages, one can just recover the last (or sufficiently
recent) working version. The real problem are silent changes removing
or breaking functionality not necessary for systemd-only systems, often
undocumented or poorly documented. Finding out which particular change broke
something can be quite a challenge.
But above all, the "do-ocracy" theory is just a big lie. People wanting
working sysvinit didn't have to _do_ anything: it was there and it
worked so there was nothing to _do_ for it, just keep it working. And
even if we wanted to keeping it working, we weren't allowed because
from the very beginning there was a premise that keeping two boot
systems is a waste of effort and that systemd is the only one worth
having. Period, end of discussion, before it even started. Well, there
was a lot of discussion but arguments of people thinking otherwise were
never given serious chance. The people with power to decide were already
determined to get rid of sysvinit, the only question really considered
was how long will it take. And this has nothing to do with "do-ocracy".

Well, TBH, keeping the two boot systems in place, interoperable and
easily switchable *was* indeed gonna be a lot of effort.
It's the same as maintaining multi-distro packages. I've done a couple
of those, and the subtle differences between the distros makes it
really difficult, especially deb-based ones which have none of RPM's
magic. With sysvinit vs systemd was the same. There was no magic in
place to make it easier, and packages that had to interact with either
would and had become a lot harder to maintain just because they had to
handle two very different init systems.

Objecting is the quickest way to get ignored and be told that anything bad
that happens on your system is your own fault for touching your system.
If people would stop touching their systems and expecting to use them for
their own purposes, they wouldn't have any problems with the way they

they affect things which worked without any problem since always ...
I had run some quick tests of openSUSE 12.1, 12.2, 12.3 which where
enough for me to see that they are unusable. I still run 11.4 on all
production machines. One of my experimental machines (desktop at home)

I would second the general complaint about software quality, having
just 'upgraded' to 12.3, the latest KDE is also a mess especially KMail
2 which is another alpha quality disaster!
There is a patten emerging here, especially in German based projects,
of Grand Ideas, that do nothing to meet user need, break existing
functionality, and are stoutly defended by evangelists and UI
designers.
It may look pretty, but just under the skin it is barely alpha quality
crap!

quirks collected trough time that allowed users to run Linux on

do nothing to fix a problem. User that installs Linux and have a
problem will just ditch new toy.

I guess that early adopters, testers and bug reporters are also those
that do the work, provided time to catch up with changes. If one pushes
more that they can swallow whole idea of testing software falls apart.
It is as simple as a streetcar (tram).
If it stops all passengers will enter.
If it slows down, those that can run and jump can enter.
If it doesn't slow down only few athletes will be able to catch a
moment and enter.
In other words, adjust your speed to ability of "passengers" you want,
or you will have no income very soon.
As it is now:
* systemd and relatives are requiring days of full time engagement to
learn, which excludes all that can't take that much time. Learning at
the slow pace is Sisyphus task, as by the time you learn something,
there is more to learn and some to forget.
* changes are at the level that backport to older openSUSE releases is
not viable, which excludes from testing all that have reasons not to
use the latest release. One of reasons is, probably, lack of time to
port application settings and data every 8 months.

Well, yeah . because guess what .. workarounds or fixes for buggy BIOS
do not belong in userspace, they have to be fixed in the kernel.

Filesystems are interchangeable, at least if I'm building a new system

Btrfs is optional, and lots of alternatives are present and usable
inside the distribution. Journal is not. One can opt-out of btrfs. One
can opt-in, in fact. Not so with journal. It's like trying to opt out
of the kernel. Difference (big difference) is, the kernel works.
Journal doesn't.
Sure, journal might work some day. But since it's not something that I
can opt-in or out, it's that day the day when it should've been
introduced into the distro, not today. Now maintainers and everybody
is hard-pressed to fix the bugs, or leave for greener lizardless
pastures.
Thankfully, I didn't have issues with Journal yet. But, I know better
than to deploy any systemd-based openSuse on a server.

You can 't opt out from the journal or systemd, both are required
components in the same sense the kernel is required or a shell is required.
I instructed you how to disable the journal storage. I think that is enough.
If you do not want those components, take a look at few distributions
that do not currently use systemd ,the list gets shorter and shorter
everyday, because systemd has become the de-facto init system by
now.currently the exceptions are debian and slackware (but they wont be
for much long I think)

There is no API for storage plugins, if you need the journal data to be
stored somewhere else you will be able to consume it via a webservice
that will be provided by systemd-journal-gatewayd or simply by using a
syslog implementation that provides the storage backends.

No one has said it should be used, you still have syslog. however
systemd requires the journal. it logs all its operations there.
you can simple remove /var/log/journal if you do not want persistent
storage..systemd will still use the journal for runtime logging or
internal operations in its own private /run/systemd/journal directory...

Journal: we consider it as a logging solution for stand alone desktops.
You can read about it in a bit more details at
http://czanik.blogs.balabit.com/2012/03/state-of-the-art-logging-syslog-ng-…
And a bit of self promotion: if you are interested in logging and/or
syslog-ng, be sure to come to the openSUSE conference in Prague, where
I'll give a presentation Sunday, early in the afternoon:

separately --
that global view is a good way to look for 'warts'...
you can query items separately or view the whole log...
