The following fields are shown on the Activity Summary report:

Gateway Id
CICS TG APPLID.
Start time
CICS TG daemon start time.
Up time
CICS TG daemon running time.
Number of intervals
For a given CICS TG daemon instance, this is a count of the SMF records written for a unique collection time.
Number of requests
Number of requests processed. This is taken from the most recent SMF record for a given CICS TG daemon instance.
Peak TPS
Peak transaction rate per second. This figure is obtained by evaluating GD_IALLREQ / GD_IRUNTIM to find the highest transaction rate across all intervals for this CICS TG daemon instance.
Peak time
Peak transaction rate interval start. This is the collection time of the interval that contained the Peak TPS value.
Connect timeouts
The number of times connect timeout occurred.
Worker timeouts
The number of times worker timeout occurred.

Usage and Capacity

The following command produces the Usage and Capacity report:

CICSPA CTGSTATISTICS(ACTIVITY,USAGE(RATIO(90),OUTPUT(ddname))

The following fields are shown on the Usage and Capacity report:

Gateway Id
CICS TG APPLID.
Start time
CICS TG daemon start time.
Collection time
Statistics collection time.
Region size
The amount of used memory ELOAL.
Region max
The amount of available memory ELIM.
Java heap size
The JVM heap size after garbage collection.
Java heap max
The JVM maximum heap size.
Clients peak
Peak number of allocated connection manager threads.
Clients max
Maximum number of connection managers.
Workers peak
Peak number of allocated worker threads.
Workers max
Maximum number of worker threads.
EXCI pipes num
Number of EXCI pipes allocated.
EXCI pipes max
EXCI pipe limit.
IPIC sessions num
Number of IPIC sessions in use.
IPIC sessions avail
Number of negotiated IPIC sessions.

The Capacity ratio is a user-defined value that can be specified in the RATIO suboperand. It is used to determine if an asterisk (*) is inserted as a warning indicator in the EXCI pipes or IPIC sessions columns when the Num to Max/Avail ratio exceeds the specified ratio. The default is 90.
