I’m a bit stuck here. Almost any time we activate changes in CMK Raw 2.0.0.p9 we get a number of hosts that will show as down with a “Null” summary. The number of hosts that will show this ranges from 1 - 100+
I’ve not found any performance or configuration issues on the monitoring sites/hosts.
We have 6 total sites with around 1400 total hosts.
The agents on all hosts have been updated to match the server version.
Any idea where I should start looking? I would appreciate any help.
