Thank Nick for your fast response. So if the OpsCenter is down, then the stats for the cluster won't be collected. Is there any safe-guard mechanism, like a duplicate OpsCenter on second machine to monitor the cluster in case of single OpsCenter failure?

The OpsCenter agents report metric data to the main OpsCenter process which processes it and writes data into the cluster. So yes, the main OpsCenter process needs to be running in order for metrics to be stored in the cluster. -Nick On Thu, Dec 15, 2011 at 9:43 AM, <mike...@thomsonreuters.com> wrote: > Hi, > > > > I have one question about OpsCeneter: does it have to be running all the > time in order to collect and store the metrics on each node within the > cluster?
