I tried, I find it cryptic.>>>> Telcontar:~ # vmstat -SM -a 15 procs -----------memory---------- ---swap-- -----io---- -system-- ------cpu----- r b swpd free inact active si so bi bo in cs us sy id wa st 1 0 1330 17369 2280 10992 0 0 332 146 51 38 6 1 92 0 0 0 0 1330 17477 2280 10882 0 0 0 16 3454 5955 2 0 97 0 0 1 0 1330 17461 2280 10901 0 0 0 27 3250 5629 2 0 97 0 0
What is each column?
man vmstat?
In one sense all manual pages are; reading them is an acquired skill. (Writing them is also a skill!) Nevertheless, RTFM.
I'll bite. "man vmstat" then search for "columns" produces nothing. I'm not the one that wants to use vmstat, so it is possible that Anton already knows and can tell me faster than me finding out :-)
You could have searched for, variously 'procs' and the other heading items.
From "man vmstat"
...
what units?
maybe MiB, because you told to use -SM.
yes, that too is in the manual :-)
Swap si: Amount of memory swapped in from disk (/s). so: Amount of memory swapped to disk (/s).
I'd prefer read/write
How is that not read/write?
IO bi: Blocks received from a block device (blocks/s). bo: Blocks sent to a block device (blocks/s).
What's a block? Maybe 1KiB.
How is you system set up? What's a disk block? Is it 4K or ore you still on 512byte disk blocks?
CPU These are percentages of total CPU time. us: Time spent running non-kernel code. (user time, including nice time) sy: Time spent running kernel code. (system time) id: Time spent idle. Prior to Linux 2.5.41, this includes IO-wait time. wa: Time spent waiting for IO. Prior to Linux 2.5.41, included in idle. st: Time stolen from a virtual machine. Prior to Linux 2.6.11, unknown
stolen? what is that?
Since I don't run a virtual machine I don't know. I suspect it has to do it you run this ON a virtual machine.
I did not see it... :-D
It was pretty blatant and unavoidable. As manual pages go, this is pretty informative. If anything, the problem is with vmstat since it can be run in many modes, all producing completely different results. There are some other XXstat programs that are a lot more awkward and obscure.
