Collecting Solr performance statistics
Enable the solr_latency_snapshot_options parameter in dse.yaml and set the other options as required.
When solr_latency_snapshot_options is enabled, the performance service creates the required tables and schedules the job to periodically update the relevant snapshot from the specified data source.
The following snapshots collect performance statistics:
- Query latency snapshot
Record phase-level cumulative percentile latency statistics for queries over time.
- Update latency snapshot
Record phase-level cumulative percentile latency statistics for updates over time.
- Commit latency snapshot
Record phase-level cumulative percentile latency statistics for commits over time.
- Merge latency snapshot
Record phase-level cumulative percentile latency statistics for index merges over time.
All objects are disabled by default.
