Getting Broker Client Statistics
The BrokerAdminClient.getClientStatsById method allows you to obtain statistics for a Broker client with a particular client identifier. The statistics are returned as fields within a BrokerEvent. You can retrieve each field using the BrokerEvent.get<type>Field method, described in the webMethods Broker Client Java API Programmer’s Guide. The version of the get<type>Field method to be used will depend on the data type of field you are retrieving.
The following example illustrates how to obtain the system usage statistics and extract the value of two fields. In this example, the client identifier is hard-coded. See
Obtaining
Broker Client Identifiers for information on discovering client identifiers at run time.
