Nagios Support Forum

Hello all well

I'm getting the error below when trying to review any report availability.

Availability date is not available When monitoring engine is not running.

Monitoring services are running normally.


Any Help ?

Can you got to Admin --> System Information --> System Status, take a screenshot, and post it here?

some features are unstable

Those are some pretty high loads, can we get some information about your system?
Let's see why cron is failing to run those jobs:

Can you try to restart crond and see if this clears it up a bit?
Let it run for about 5 minutes...
