No agent, no plugin..what can Nagios XI monitor?

[ikekim]

Hi,

What things could Nagios monitor without using anything being installed on the target host machines?

If there is no NRPE agent or no plugins are being used no snmp client, etc , what type of basic things could Nagios XI monitor and show it in the management console?

Can I monitor target host machine's PING status, URL (if has web page), etc.



thanks,
ik

@ikekim, Yes, you can certainly set up a ping check for your host in Nagios XI without installing any plugins and create a check with HTTP/HTTPS request to a custom URL(Check out the "Website" config wizard in XI). It can also probably do a basic ssh checks without any plugin on the client side provided that there are no firewall restrictions(aka server uptime check). You can check for things like domain expiration, whether or not it's on the blacklist. You can check whether IMAP or POP servers are UP. You can do TCP checks as well.
Very often you can monitor things like UPS and printers, routers and switches without installing any plugins on their side because they already have SNMP factory preinstalled.
I guess it all depends on what your goals are. Is there anything specific you're trying to achieve?

@npolovenko,

Thanks for that info and they are really useful for me. I'm struggling with internal procedures and processes to have agents or plugins installed or do any configurations on AIX servers because they are managed externally. It may be like trying to do an ultra marathon race, but with very short time window.

So the next best thing I can do before the expected deadline, I want to receive monitoring information on, host being up, web URL & site working, URL logon working, etc.

Your response gave me more in depth info on what I can do which I will try out.


thanks again,
