Resolution: Duplicate
> Invalid Prometheus JVM pool metric names with Java versions greater than 8
> --------------------------------------------------------------------------
>
> Key: IMPALA-13640
> URL: https://issues.apache.org/jira/browse/IMPALA-13640
> Project: IMPALA
> Issue Type: Bug
> Components: Backend
> Reporter: Peter Rozsa
> Assignee: Peter Rozsa
> Priority: Major
>
> JVM pool names changed from version 8 to 9, for example:
> [https://github.com/openjdk/jdk/commit/3525490c577b2d888a4b071158273dc5123403a8]
> This causes invalid Prometheus metric names, like:
> impala_jvm_codeheap_'non_profiled_nmethods'_peak_init_usage_bytes
> JVM pool names should be sanitized before creating metrics from them
