I have a strange problem with my Grid Control 126.96.36.199 Management Server in a Solaris 10 zone. When restarted, the OMS will serve requests fine for about 2 to 4 hours and then “hang”. Checking the Admin Server console I can see that there are stuck threads. The same information is also recorded in the logs.
NB: the really confusing part about Grid Control 11.1 is the use of Weblogic-you thought you knew where the Grid Control logs where? Forget about what you knew about 10.2 and enter a different dimension :)
So to be able to react quicker to a hang of the OMS (or EMGC_OMS1 to be more precise) I set up nagios to periodically poll the login page.
I’m using a VM with OEL 5.5 64bit to deploy nagios to, the requirements are very moderate. The install process is well documented in the quickstart guide-I’m using Fedora as a basis. OEL 5.5 doesn’t have nagios 3 RPMs available, so I decided to use the source downloaded from nagios.org. The tarballs you need are nagios-3.2.3.tar.gz and nagios-plugins-1.4.15.tar.gz at the time of this writing. Read the rest of this entry »
