I have successfully installed the NRPE agent for AIX on all my AIX 5.3/6.1 Logical Partitions (LPARs). The software gets installed in /opt/nagios.

However, I want to install the agent on some of our Workload Partitions (WPARs). The /opt filesystem on the WPARs is a read-only copy of the /opt filesystem on the hosting global LPAR. So, I need to install it in a different location (say /usr/local/nagios).

Is there a way to tell the fullinstall script to install the software to an alternate install path?

Also, is there an agent yet that supports AIX 7.1?

Thanks!

P.S. I have developed an install script that installs all the required prerequisites and installs the agent without any user input if anyone is interested!

you would need to edit the paths in init.sh as well as in nrpe/mods/cfg/nrpe/common.cfg to the desired paths before installing..

I could have sworn that I had posted this before, but I'll try again:

I figured out how to get it to work. You don't need to install the NRPE agent on the WPAr. You just need to configure it:

1. The NRPE agent must be installed on the global LPAR
2. On the global LPAR, copy the /etc/nagios directory to the WPAR:

Code: Select all

cp -r /etc/nagios /wpars/wpar_name/etc/.

3. Copy over file your Nagios install file to /tmp on the destination host
4. Become root: sudo su -
5. Run cd /tmp
6. Unzip and untar the install file
7. Go into the install directory
9. As root, run ./0-prereqs and then ./1-usersgroups
10. Create an SRC entry on the WPAR for nrpe:

Code: Select all

mkssys -s nrpe -p /opt/nagios/bin/nrpe -a "-c /etc/nagios/nrpe.cfg -d -s" -u 0 -R -d -S -n 15 -f 9

11. Start the nrpe service:

Code: Select all

startsrc -s nrpe

12. Verify that the nrpe service and Nagios is running:

Code: Select all

	# lssrc -s nrpe
	Subsystem         Group            PID          Status
	 nrpe                              15138862     active
	root@host:[/etc/nagios/nrpe]
	# ps -ef | grep nagios
	    root 11141294 18284774   0 14:50:19      ?  0:00 grep nagios
	  nagios 15138862  6488214   0 14:50:11      -  0:00 /opt/nagios/bin/nrpe -c /etc/nagios/nrpe.cfg -d -s

13. Create /etc/inittab entry:

Code: Select all

mkitab nrpe:2:once:"startsrc -s nrpe >/dev/null 2>&1"

Excellent information thank you for the explanation.
