-----------------------------------------
Assignee: Chris Lohfink (was: Chris Lohfink)
> Add heap dump inspections to sidecar
> ------------------------------------
>
> Key: CASSANDRA-15043
> URL: https://issues.apache.org/jira/browse/CASSANDRA-15043
> Project: Cassandra
> Issue Type: New Feature
> Components: Sidecar
> Reporter: Chris Lohfink
> Assignee: Chris Lohfink
> Priority: Normal
>
> Add to ui a tool to view heap dumps cassandra produces when OOM to identify
> the issue that caused it. Three views
> 1. C* inspections - useful inspections like a list of the largest partitions,
> most active partitions, largest (and most by table and partition) mutations.
> 2. Threads - their stack traces, heap size, and values of things in local
> processing scope (that can be clicked through and explored)
> 3. Metrics - view state of all the metrics at time of heap dump
> Additional requirement: since this runs on cassandra sidecar it should use
> very low memory (ie sub 100mb) and not consume massive cpu
