• New configuration option: SPLUNK_DEBUG_METRICS_ENABLED / metrics.debugMetricsEnabled. #700 When set, extra set of internal troubleshooting metrics are produced. This should only be enabled to assist debugging. Defaults to false. Currently debug metrics for the CPU and memory profiler are produced, each being a histogram:
  • splunk.profiler.cpu.start.duration
  • splunk.profiler.cpu.stop.duration
  • splunk.profiler.cpu.process.duration
  • splunk.profiler.heap.collect.duration
  • splunk.profiler.heap.process.duration
