Monitoring RHEL 3 and RH 9, Part 2...

[PhilG]

Hello:
I posted this before - http://support.nagios.com/forum/viewtop ... 16&t=29051 - and my colleague was running into some issues on RHEL 3 servers (didn't do RH 9).

So, to stop banging our heads, we were looking at the following suggestions from http://www.nagios.com/solutions/rhel-monitoring
1). Can try "passive" checks using "NRDS" - http://labs.nagios.com/2014/03/19/how-t ... nagios-xi/
2). Can try using SNMP - http://assets.nagios.com/downloads/nagi ... g_SNMP.pdf
3). Can try using SSH - http://assets.nagios.com/downloads/nagi ... ng_SSH.pdf

With those three suggestions, I have the following questions:
For 1). it appears that the process installs the needed plug-ins on the remote server which needs to be monitored, correct?

For 3). It states:
"Before you can use the check_by_ssh plugin, you must install/configure the following on the remote Linux/Unix server you want to
monitor:
• Create a nagios user
• Install Nagios plugins and/or monitoring scripts
• Install and configure the SSH daemon
"

Thank you.
but there is no information in the document that tells "where" and "how" to install the plugins and scripts, nor what needs to be configured with the SSH daemon.

for 3) we are siimply saying that you must have a working ssh daemon that nagios can connect to. This is nothing unique to us. As for plugins and scripts, they can really be placed anywhere you are comfortable with, that can be accessed by that nagios user.
for 1) yes it should places them in the correct location for nrdp\nrds, which by default should be something like /usr/local/nrdp/libexec/ or /usr/local/nagios/libexec
