Need help with resolving a host availability reporting issue.
After a hardware problem on 10/02, I experience some nagios database corruption but the recommended recovery procedures appeared to resolve any problems. However, it was recently brought to my attention that most of the hosts were not reporting availability, or were indicated as down although they are up. The last hard status change indicated in the logs was on 10/02. I've truncated the nagios_hoststatus table which was the only table with any significant damage with no impact on the problem. Attached is a picture from the availability report from Nagios core which indicates the problem.
I need to figure out how to get the host availability reporting back to normal. Any suggestions are appreciated.
