Displaying Process Statistics
The STATS SUBSYS display indicates the number of register requests APLMGR has
received from user applications. The values returned for the register requests may be
important to monitor. If several requests have been attempted and none has succeeded,
the request might not have been able to find the resources it needs. Use the SCF INFO
command to check the current configuration, the SCF STATUS command to verify that
there are available initiators in the STARTED state, and then the ALTER command, if
necessary, to correct any problem.
Displaying Process Statistics
To monitor the activity of an FTAM initiator or responder process, use the STATS
PROCESS command. This command allows you to collect process statistics and track
the activity for the APLMGR and FTAM processes running on the system.
To collect statistics for the responder $FTR1 in the example FTAM configuration (see
Example FTAM Configuration
on page 3-38), issue the STATS PROCESS command as
follows:
STATS PROCESS $FTR1
This command returns the following display:
This display shows that there are two open control block and six request control block
table entries currently in use, and gives the number of each type of file-system request
made since the counters were last reset.
The STATS PROCESS command returns information on the internal activity of the
process. The file-system request information enables you to look at file activity and
determine if the number of file-system requests of different types is reasonable for the
sample time. For instance, a large number of WRITEREAD file-system requests might
indicate a need to redistribute the workload. You can use SCF LISTOPENS PROCESS
and STATUS SU to locate overworked processes and use the ALTER command to adjust
the configuration to distribute the workload more evenly.
