Counters

Overview​

The Counters tool provides a simple CLI interface for viewing Ember performance counters. For more information, refer to the Ember Monitoring Guide.

Sample Usage​

You can use the Counters tool to display specific counters that match a given wildcard pattern. Here's an example that displays all counters that have Order in their name:

$ /deltix/ember/bin/counters -filter *Order*

15:37:13 - Ember Stat
=========================
  1:           16,540,727 - Ember.TotalOrders
  3:                7,523 - Ember.ActiveOrders
 10:                   29 - Ember.UnknownOrderEvents
 12:               37,799 - Ember.OrdersPoolSize
 13:              219,567 - Ember.OrderEntriesPoolSize

The output shows the counter IDs, their corresponding values, and the counter names that match the provided wildcard pattern.

Command Line Arguments​

The Counters tool accepts the following command line arguments:

  • -filter <wildcard-pattern> - Use '*' as a wildcard symbol to specify the counters you want to display. This argument can be specified multiple times to apply to multiple filters.
  • -filter @<wildcard-filename> - Similar to the above option, but the wildcard patterns are read from a file. Each line in the file represents a separate filter.
  • -file <counters-file> - Specifies the location of the Ember counter file. If this argument is skipped, the tool uses the EMBER_WORK or EMBER_HOME environment variable to locate the counters file.
