Monitoring Human Task Service Component Instances and Faults

Monitoring Human Workflow Service Components and Engines 20-9 ■ Active requests in the service engine. Use this graph to get an idea of the current service engine load. Only under extreme load conditions is there data shown in the graph. This is because most requests are processed instantaneously by the service engine. The data is collected by a Dynamic Monitoring Service DMS state sensor. Once the requests are processed by the service engine, the count goes to zero. This action enables you to know the current load on the service engine for example, if it is too high. ■ Average request message processing time in the service engine since the last startup of the SOA Infrastructure. Use this graph to check service engine performance. Note that while the processing time is calculated based on the last startup of the SOA Infrastructure, the data that is displayed in the graph is gathered only from the time at which you first accessed this page. The graph does not continue calculating and displaying data if you have not accessed this page. The DMS phase event sensor calculates the average request processing time and provides the processing time data. ■ Operation statistics about human workflow services used in the service engine, including the human workflow service used, the operation performed by the service, the number of active and completed requests, the count, and the average processing time.

20.6 Monitoring Human Workflow Service Engine Instances

You can monitor all human task service component instances running in the service engine. These human task service components can be part of separate SOA composite applications. To monitor human workflow service engine instances: 1. Access this page through one of the following options:

2. Click Instances.

The Instances page displays the following details: ■ A utility for searching for a specific instance by specifying criteria and clicking Search . ■ Instances, including the instance ID of the service component, the service component, the SOA composite application of which the service component is a part, the state of the instance for example, completed, running, or faulted, the instance start time, the last modification time, and links to log files that describe the instance.

3. In the Instances section, perform the following additional tasks:

a. In the Instance ID column, click an instance ID for a service component to
