Can Nagios Agent hold the data

[shivangi]

Hi Team,

I was working with nagios core and wanted to know if nagios agent can hold the data for some time and push it back to the nagios server when requested .( in case communication with nagios server breaks down )

If Yes , then which nagios Agent is suitable for this need ?

Thanks in advance

Hi @shivangi,

I think passive checks would work you. The Nagios server does not reach out to the remote hosts, but rather the remote hosts will send it results periodically back to the Nagios server to be processed and alerted on (if necessary).

The Core Docs are the source for all things Core and cover how passive checks work in detail on the following page.

You can used NRDP/NCPA to transfer check results back to Nagios, below are few relevant docs for getting started. Good luck and let us know how it goes.

Hello benjaminsmith ,

Thankyou for the response , i was going through the documents and actually my requirement it to use only nagios agent to collect the performance data and store it in for some time ( say 3 hours ) without nagios server intervening and push the data when it finds the server up again .

Thanks

Hi ,

I was going through the documents and couldnot get to know where does the nsca stores the results of its passive checks if the nrdp server is not available so that it can retrieved later .

Thanks .
