Brandon Williams commented on CASSANDRA-12197: ---------------------------------------------- So much +1 on this. I've had to ask people to install sjk so many times to troubleshoot something I've lost count. Excellent tool that we should integrate. > Integrate top threads command in nodetool > ----------------------------------------- > > Key: CASSANDRA-12197 > URL: https://issues.apache.org/jira/browse/CASSANDRA-12197 > Project: Cassandra > Issue Type: Improvement > Reporter: J.B. Langston > Priority: Minor > > SJK (https://github.com/aragozin/jvm-tools) has a command called ttop that > displays the top threads within the JVM, sorted either by CPU utilization or > heap allocation rate. When diagnosing garbage collection or high cpu > utilization, this is very helpful information. It would be great if users > can get this directly with nodetool without having to download something > else. SJK is Apache 2.0 licensed so it might be possible leverage its code. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
