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. We're using Oracle Java version 1.8.0_45. * PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND* 31501 cassandr 20 0 3599m 296m 14m S *339* 2.0 48:20.39 /opt/jdk/jdk1.8.0_45/bin/java -Xmx128M -Djclouds.mpu.parts.magnitude=100000 -Djclouds.mpu.parts.size=16777216 -Dopscenter.ssl.trustStore=/var/lib/datastax-agent/ssl/agentKeyStore -Dopscenter.ssl.keyStore=/var/lib/datastax-agent/ssl/agentKeyStore -Dopscenter.ssl.keyStorePassword=opscenter -Dagent-pidfile=/var/run/datastax-agent/datastax-agent.pid -Dlog4j.configuration=file:/etc/datastax-agent/log4j.properties -Djava.security.auth.login.config=/etc/datastax-agent/kerberos.config -jar datastax-agent-5.1.3-standalone.jar /var/lib/datastax-agent/conf/address.yaml The logs from the agent looks strange to me: https://gist.github.com/kluyg/21f78af7adff0a940ed3 The cluster itself seems to be fine, the load is small, nothing bad in Cassandra system.log. Does anyone know what to tune to bring it back to normal? Thanks, Mikhail
