IBM Streams 4.3.0

Monitoring processing elements

Use the Streams Console or the streamtool lspes command to view the status of processing elements (PEs) in an IBM® Streams instance.

About this task

You can view information only for the PEs that you are authorized to work with, as determined by the access control lists for IBM Streams.

Procedure

Monitor processing elements in the Streams Console.
Run one or more of the following commands:
- The streamtool lspes command provides a health summary for each PE.
- The streamtool displaype command displays details about a specific PE, including the configuration settings that are used by the PE.
- The streamtool capturestate command provides more detailed information about the system health.
For more information about command syntax and options, enter streamtool man command-name.

Results

The command and Streams Console output includes status information and a health summary for each PE. If a PE is running and all of its required and optional connections to other PEs are currently connected, IBM Streams reports that the PE is healthy.
