RMF Workload Activity reports and RMF Monitor III
Performance metrics include transaction rates and response times. Resource utilization includes CPU, I/O (channel), and storage utilization.
- Transactions/second
- This is shown in the AVG, MPL, and AVG ENC fields which is equal to the average number of enclaves in the period in the RMF Monitor I report.
- Response times
- The actual response times of the WLM transaction is shown in the TRANS.-TIME SS.TTT' column in
the
RMF Monitor Ireport and are measured in milliseconds. (This also includes time waiting on WLM queue.) - Service Rates
- Resource utilization in CPU service units, and Service Units per Sec. The APPL% field shows the number of processor engines (CPs) required to drive the work in the service (report) class.
Controller Regions Example: Here is the report for the WebSphere® controller regions which
were all assigned a particular reporting class according to the STC classification rules based on
the started class jobname. There is only one transaction active in the system, there are no response
time figures, and required 37.2% of a processor engine to support its work.

Servant Regions Example: Here is the report for the WebSphere servant regions which were all assigned a
particular reporting class according to the STC classification rules based on the stared class
jobname. There are only two transactions active in the system (meaning there were two servant
regions), there are no response time figures, and they required 10% of a processor engine to support
their work.

Transactions (Enclaves) Example: Here is the report for the real WebSphere transaction work which
runs as enclaves in this particular reporting class. The average number of these kind of
transactions active in the system was 241.52, the average response time was 276 milliseconds, and
required 2.129 processor engines to support this work.

Server Region to select work off the WLM queue. Here is a queue delay report which shows that work
was delayed 23.5% of the time waiting for the CPU and 12.6% of the time waiting for a servant
region:

in WLM which can be used to classify the non-enclave time in the websphere server regions. WebSphere production
controller region with a jobname of WSPRODC is assigned a service class of STCCR and reporting class
of RCTLREG, production controller region with a jobname of WSPRODC is assigned a service class of
STCSR and reporting class of RSRVREG, and testregions (servant and controllers) with a jobname
starting with WSTare assigned a service class of STCWSTST and reporting class of RWSTST.
