|Managing Pivotal GemFire / Statistics|
Each application or cache server that joins the distributed system can collect and archive statistical data for analyzing system performance.
Set the configuration attributes that control statistics collection in the gemfire.properties configuration file. You can also collect your own application defined statistics. To view and analyze archived historical data, use the Visual Statistics Display (VSD) utility provided in a separate download from the product. Contact VMware technical support for instructions about acquiring VSD.
Statistics sampling provides valuable information for ongoing system tuning and troubleshooting. Sampling statistics (not including time-based statistics) at the default sample rate does not impact overall distributed system performance. We recommend enabling statistics sampling in production environments. We do not recommend enabling time-based statistics (configured with the enable-time-statistics property) in production.
