i'm running on one node to check the datastax-agent status
sudo service datastax-agent status
can i know the status of all nodes without doing SSH to other nodes in the cluster ?
How can I check the status of OpsCenter agents without connecting with SSH to the nodes?
What you are trying to do is counter-intuitive -- you want to monitor the thing that is doing the monitoring for you.
When the agent goes down or becomes unresponsive, OpsCenter (opscenterd) will notify you of the problem. That's what OpsCenter is designed to do.
You can in fact see the status of the agents in the OpsCenter web UI in the DataStax Agents Status View. You can also add alerts for agent issues. Since you're already using OpsCenter, you should use it to monitor the cluster for you.
For more information, see Configuring alerts for cluster events. Cheers!
