Don't want to be rude, but http://nagios.sourceforge.net/docs/2_0/toc.html is quite verbose. Maybe SuSE has already prepared appropriate entries in httpd.conf. Just have a look at it. \Steve

Well, same advice, but I think the version included with SuSE 9.3 is actually 1.3, so http://nagios.sf.net/docs/1_3/toc.html is where you want to start looking.

Maybe right, I actually don't know. Thanks anyway. \Steve

I suppose you're using PPPOE (i.e. you're not connected to a DSL router). Change the MRU and MTU values in the following files: /etc/ppp/options /etc/ppp/peers/pppoe change the values to mtu 1492 mru 1492 and uncomment the same lines in file /etc/ppp/options and change their values accordingly. That should do it (I hope at least). \Steve

Thanks, just thought maybe there was already a default, and I didn't want to break anything as usual. :) -- Chadley Wilson Research Technicain =========================================== Redhat Certified Technician Cert Number: 603004708291270 Pinnacle Micro Infinite Possibilities, Infinite Solutions Manufacturers of Proline Computers =========================================== Exercise freedom, Use LINUX ===========================================

Greetings,

nagios seems to be included in Suse 9.3, how do I set it up?

Well, the very very basic beginning steps: - Install the RPM. Also install apache2, since Nagios requires a web interface. - Edit /etc/nagios/*.cfg to suit your needs. This _will_ require a whole bunch of time with the Nagios docs, because it's not easy to configure. * Start with /etc/nagios/nagios.cfg, and alter that as needed. * Add contacts, as needed, to /etc/nagios/contacts.cfg. If you want SMS pager notifications, use the e-mail notification type and whatever e-mail address your cell carrier provides to send SMS via that method. The "Pager" method assumes a configured modem on the Nagios server, and will try to dial to send the alert. * Group contacts, as needed, by altering /etc/nagios/contactgroups.cfg. * Add hosts to /etc/nagios/hosts.cfg. Put some real thought into what hosts you want to monitor. * Group hosts in /etc/nagios/hostgroups.cfg. Again, put some real thought into this, because hostgroups allow you to control notification settings for a large number of machines at a time. Also, remember that a host can be in multiple groups at a time. For example, I've got a group called WebServers (all www machines); another called "WebServersIDE" (all www machines with /dev/hdX drives); and another called "WebServersSCSI". * set up service checks in /etc/nagios/services.cfg. Again, think carefully about what you want for notification periods and the like. (Remember, the goal is always getting more sleep.) This is where hostgroups come in handy. I've got a couple of service checks set up for the "WebServers" group that are general, but then separate disk-space checks for "WebServersIDE" and "WebServersSCSI". This is where I guess I should throw in the caveat that the Nagios RPM included with SuSE, though functional, didn't really work for my particular case. I'm managing a complex environment, and once I got the point of using multiple Nagios machines, passive checks, and so on, I ended up having to roll my own RPM. Beyond that....Good luck! And may nagios never alert you to _anything_. - Ian

You can get Groundwork's Monarch from sourceforge to help with setting up Nagios "after" you get the basic setup done. It's provides a web frontend to the Nagios config files. http://sourceforge.net/project/showfiles.php?group_id=130574 http://itgroundwork.com/products/gwm-architect.html John
