Generating statistics reports

You can generate statistics reports that provide information about the performance of your brokers.

Use these statistics reports to show you where there are performance problems in your broker network. You can then change the properties of the brokers that might affect performance. These properties are described in Performance considerations for Real-time transport.

By default, statistics reporting is disabled. To enable statistics reporting:

  1. Use the property statsInterval of the mqsichangeproperties command:
    mqsichangeproperties <broker name> -e <execution group> -o DynamicSubscriptionEngine
                         -n statsInterval -v <time interval>
    where <broker name> is the name of the broker whose statistics you want to be reported, <execution group> is the name of the execution group deployed to the broker, and <time interval> is the number of milliseconds that should separate statistics reports.

    There is a small performance overhead when statistics reporting is enabled; the smaller the time interval specified, the larger the performance overhead.

  2. Restart the broker.

To disable statistics reporting, use the same procedure, but set the value of the statsInterval property to 0.
