Sentry Statistics

You can download statistics for Sentry operation. These statistics encompass the entire Sentry implementation and all connecting devices. They are most useful for charting true activity peaks so that you can schedule maintenance appropriately. Also, technical support can use these statistics for troubleshooting issues.

When Sentry Statistics is enabled or when Start is selected, the settings persists across Sentry restart. The settings in Sentry Statistics are saved as the following properties in /mi/alcor/config/v2/local/alcor-local.properties:

alcor.local.config.enable.sentry.global.statistics.report=true
alcor.local.config.statistics.log.interval.min=5

Sentry statistics collection is a continuous process. If Sentry statistics is started, the statistics are written to global-stats.csv. When Standalone Sentry restarts, the data is archived.
