clean Opscenter info for cluster
Hi
We were having some issues with different versions in our cluster and the info which appear in Opscenter. We decide to delete the datastax-agents in each of the nodes and delete the cluster from the opscenter.
But I still see on the opscenter logs attemps to retry connections to the nodes on the cluster:
WARN: Error attempting to reconnect to 172.31.7.247, scheduling retry in 60 seconds: errors=Timed out creating connection, last_host=None

The cluster works perfectly, it is only the opscenter. Is there in opscenter any kind of cache which maintain info about old cluster condifgurations?
Thanks in advance for your help

Hi
At the end, we have solved the problem deleting also the Opscenter keyspace from the cluster and restarting the opscenter. Then the retry attemps to the old nodes in the cluster disappeared.
