Nagios experts - a quick question please

[kylebreit96]

So I'm involved in a team that are getting an exiting MSP to deploy Nagios to the environment.

They already use it, but we are getting a brand new instance of our own. The agents already are deployed.



My question is, how long would it take to reconfigure existing agents to the new Nagios server? Is there a simple command, or is it redeploying the agent, and how many can you do per day?

We're being told it is slow, only 5 per day and must be redeployed. Given this will be monitoring a few hundred systems, this is pretty average



Can anyone weigh in please?

Assuming nrpe is run by xinetd the /etc/xinetd.d/nrpe file needs updated and xinetd restarted.
This can easily be done by ansible if you have a user that can login and sudo. You just need a playbook to replace the file and restart xinetd. Of course you need to install ansible on some host...
If you want to update nrpe by reinstalling it, ansible can do that pretty easily.
