The policy engine hub includes three performance objects that are useful when diagnosing hub problems. In the Performance applet (accessible from Administrative Tools), you can add a range of useful performance objects. For each performance object, you can specify which counters and, where relevant, instances you want to view.
Note: On a 64-bit system, all CA DataMinder performance counters, including counters for a 32-bit policy engine hub, are supported in the default 64-bit version of the Performance applet. See the following section for details.
For policy engine performance object details, see 'Monitor Policy Engines' in the Platform Deployment Guide.
For policy engine hubs, the following performance objects are available:
Available only as a single instance. This contains counters for the policy engine hub itself. For example, you can see the number of active, standby and connected policy engines, the number of pending events in the hub input queue, the number of event failures, and the total memory allocated to events in the queue.
Multiple instances available; one per policy engine. This performance object contains counters for hub connections to individual policy engines. To view counters for a connection to a specific policy engine, select its corresponding instance.
Available counters show statistics such as the number and rate at which events are being passed to the policy engine and the internal state of the policy engine, for example, ‘inactive’, ‘processing’ and ‘dead’ (if you encounter a problem with a policy engine, Technical Support may ask for details of its internal state).
Multiple instances available; one per event queue on the hub. For each instance, this performance object contains counters for individual policy engines. To view counters for a specific queue, select its corresponding instance.
Available counters show statistics such as the queue size band (in bytes), the number of active and standby policy engines available to process the queue, and the number of items assigned to the queue.
