Nagios Support Forum

I am a brand newbie to Nagios. I'd like to monitor my network using agentless snmp monitoring, but am unsure about where to find some specific and solid documentation about this topic. Can anyone help?? I will be using the check_snmp_int plugin, and I want to get started monitoring all the services possible.

Below are a couple documents and an exchange link to some snmp addons. Start there and when you have more specific questions we are here to help.

Beautiful, thank you so much!!

My boss wants to use subagents to verify services outside the standard checks, but, I am not sure where to find these subagents?? Are these like the add-ons??

Are you referring to something like nsclient or nrdswin?

This is what he was referring to: http://net-snmp.sourceforge.net/wiki/in ... ll_scripts Sorry for the confusion

Some plugins on the exchange use snmp but are wrapped in a script for better functionality/more logic. If you do not find a script that meets your specific needs, you are left with writing your own.

The link you provided is about how you can map OIDs (or MIBs) to executables. You can configure snmpd to respond to certain queries by running a program and returning the output. For example you could configure snmpd to run a df instead of querying the standard disk OIDs. It can be whatever you want, as long as the output is appropriate and you have configured snmpd properly.

Hope this helps,

Wezelboy's suggestion is spot on. Philfly, is that what you were looking for?

Thanks for the help you guys !! Since I am a beginner, I am still trying to grasp SNMP, nevermind the subagents... But, I am moving along slowly, sort of trying to decipher which literature will be most helpful !!! Again, thank you very much !!
