Okay, so I've got a bunch of sql servers that I'm monitorig. Among them is sql-04 (xx.xxx.xxx.64) and sql-06 (xx.xxx.xxx.57). Now, I just started monitoring sql-06 today. I configure it in hosts.cfg with the .57 address. I had some issues with NRPE on sql-06 and was receiving NRPE notifications about...sql-04??? :o NRPE is not even on sql-04. What's more, the IP address in the notification e-mail was the .57 address (sql-06). I've double-checked my hosts.cfg configuration here, and I'm definitely defining sql-06 with the .57 address. Checking the host info on the web interface shows it with that address.
And yet...both of my Nagios servers are giving it the sql-04 hostname, with the sql-06 IP address, in their alerts. :? Can't figure what's up with that. Any ideas?
