> GraphiteReporter stops reporting from Memory concurrent access
> --------------------------------------------------------------
>
> Key: CASSANDRA-13840
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13840
> Project: Cassandra
> Issue Type: Bug
> Components: Legacy/Observability
> Reporter: Michael Semb Wever
> Assignee: Michael Semb Wever
> Priority: Normal
> Fix For: 2.1.x
>
>
> Gauges in the GraphiteReporter can, when getting compression offheap size,
> trip over the assertion in {{Memory.size()}}. As the GraphiteReporter only
> handles Exceptions this crashes the reporter and it sends no more metrics.
> [~benedict] described it
> [here|https://issues.apache.org/jira/browse/CASSANDRA-9625?focusedCommentId=14711914&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14711914]
> and [~jbellis] confirmed that it's now ok to remove the assertion.
