I am using DSE-2.2 and OpsCenter-2.1.2. I have noticed several times that OpsCenter agent status on the dashboard is very inconsistent. If I shutdown all the agents in a 3 node cluster, I still see all the agents up in the dashboard. Is this a known issue/bug?

Agent Status Inconsistent(5 posts) (2 voices)
Currently OpsCenter will cache the most recent attempt to ping the agent for 30 minutes. This means if you load the UI, OpsCenter detects the agents, and then you shut down all agents, it can take 30 minutes before OpsCenter will recognize the agents are down.
A workaround if needed, would be to restart the OpsCenter process.
Thank you. Is there a configurable parameter to reduce it to less than 30 minutes?
Besides that, I have also noticed that when I cleanup a node via OpsCenter, it hangs around at 60% while in reality the cleanup would have completed long time back. Is this also related to cache?
Unfortunately it is not configurable at the moment. We've made a note to potentially reduce/remove that caching in the future.
You could see the behavior you are describing if OpsCenter lost connection with the agent during the cleanup. Restarting the agent should fix the issue.
Nick - I did restart the agent and see. It did not help.
Restarting OpsCenter daemon and the agent did helped me.
