Re: OpsCenter datastax-agent 300% CPU

Hi all & Sebastain We recently encountered similar issue. At least we observed agent constantly died with OOM. Unfortunately, we are still with 1.2.X and it will be a while before we can totally move to Cassandra 2 series. Is there a backport patch to fix OOM in OpsCenter 5.1 branch? Please

OpsCenter 5.2 has a couple of fixes that may result in the symptoms you described: http://docs.datas tax.com/en/opscenter/5.2/opsc/release_notes/opscReleaseNotes520.html - Fixed issues with agent OOM when storing metrics for large numbers of tables. (OPSC-5934 - Improved handling of

Re: OpsCenter datastax-agent 300% CPU

What version of the agents and what version of OpsCenter are you running? I recently saw something like this and upgrading to matching versions fixed the issue. On Jul 14, 2015 2:58 PM, "Mikhail Strebkov" wrote: > Hi everyone, > > Recently I've noticed that most of

OpsCenter datastax-agent 300% CPU

Hi everyone, Recently I've noticed that most of the nodes have OpsCenter agents running at 300% CPU. Each node has 4 cores, so agents are using 75% of total available CPU. We're running 5 nodes with OpenSource Cassandra 2.1.8 in AWS using Community AMI. OpsCenter version is 5.1.3. W

Re: Is there a way to remove a node with Opscenter?

Found my mistake: I was typing the command on the node I was trying to remove from the cluster. After trying the command on another node in the cluster, it worked (`nodetool status` shows the node as removed), however OpsCenter still does not recognize the node as removed. Any ways to fix
