show activity

Report counters related to internal process events.

Description

Report counters related to internal process events of interest to developers and experienced troubleshooters.

Output consists of one line per metric accompanied by per-thread counters. Counters are 32 bit and wrap during the process's lifetime. Counters may be reset with the clear counters command.

On multi-threaded deployments, the first column indicates the total (or average, depending on the nature of the metric) for all threads. The list of all threads' values is represented between square brackets in the thread order.

Optionally, specify an argument:

  • Specify a thread number to dump only that thread.

  • Specify 0 to report the aggregated value (column 1).

  • Specify -1 to display all columns (the default).

Examples

Show all counters.
