This article gives an overview of how to enable and use the System
Management Facilities (SMF) to collect and record system and job-related information.
System Management Facilities (SMF) can be enabled to collect and
record system and job-related information on the WebSphere Application Server for z/OS system.
This information can be used to bill users, report system reliability, analyze
your configuration, schedule work, identify system resource usage, and perform
other performance-related tasks that your organization may require.
You
can enable SMF recording for:
- Capacity planning, to determine:
- How many transactions have run?
- What is the average and maximum completion time for methods running on
each server?
- How many clients are attached to each server instance? Of these clients,
how many are active?
- Application profiling:
- To show an application broken down into its component parts.
- To provide timing information on the application's component parts.
- Error reporting:
- To detect and record soft failures (those that are generated through an
exception or those that are performance-related).
- To use this error information to trigger an event that will cause an action
to occur once a threshold has been reached.
