Nagios Support Forum

I was just notified by a network engineer that my NagiosXI server is attempting to hit mirror.nexcess.net and it's being blocked by the ASA. It looks like that is a REPO site and I'm assuming maybe Nagios was looking to it to see if there were updates available? Is there anyway to validate that?

System info - NagiosXI 2012R2.3 running on RHEL 5.9 (2.6.18-348.4.1.el5).

It is most likely checking for updates against that address as they are a mirror for many of the popular distros. I don't believe XI would be doing this, but rather the server itself.
