Enhanced instrumentation

CICS® TS 5.5 continues the expansion of information that is reported by the CICS monitoring and statistics component. This section describes the extra data that is now available in the CICS statistics and monitoring SMF records.

The DFHSOCK performance group

The following new field was added to the DFHSOCK performance group:

New connection indicator (field SOCONMSG): Indicates whether the task processed the first message for establishing a new connection for a client.

For more information about counters that are available in the DFHSOCK performance group, see Performance data in group DFHSOCK.

The DFHWEBB performance group

The following fields were added to the DFHWEBB performance group:

WEB OPEN URIMAP request elapsed time (field WBURIOPN): Indicates whether the task processed the first message for establishing a new connection for a client.
WEB RECEIVE and WEB CONVERSE receive portion elapsed time (field WBURIRCV): The total elapsed time that the user task was processing WEB RECEIVE requests and the receiving side of WEB CONVERSE requests that are issued by the user task. The sessions these requests target to are opened by the WEB OPEN URIMAP command.
WEB RECEIVE and WEB CONVERSE send portion elapsed time (field WBURISND): The total elapsed time that the user task was processing WEB SEND requests and the sending side of WEB CONVERSE requests that are issued by the user task. The sessions these requests target to are opened by the WEB OPEN URIMAP command.
Node.js application name (field NJSAPPNM): Node.js application name from which the task was started.

For more information counters that are available in the DFHWEBB performance group, see Performance data in group DFHWEBB.

The DFHWEBC performance group

The following fields were added to the DFHWEBC performance group:

INVOKE SERVICE request elapsed time (field WBSVINVK): The total elapsed time that the user task was processing INVOKE SERVICE requests for WEBSERVICE resources.

For more information about counters that are available in the DFHWEBC performance group, see Performance data in group DFHWEBC.

ISC/IRC system entry resource statistics

The following new field was added to the collected ISC/IRC system entry resource statistics:

Peak aids in chain (field A14EAHWM): The peak number of automatic initiate descriptors (AID) that were present in the AID chain at any one time.

The example is from a sample ISC/IRC system entry resource statistics report produced by CICS TS V5.5 DFHSTUP report and shows the new statistics field.

Connection name. . . . . . . . . . . . . . . . . :     FOR

Policy statistics

Statistics are now available for CICS policy rules. CICS collects resource statistics for each rule that is defined in a policy, and supplies a summary report.

The example is from a sample policy statistics report produced by CICS TS V5.5 DFHSTUP for an installed policy.

Policy name. . . . . . . . . . . . :  file_v51
Policy user tag. . . . . . . . . . :
Bundle name. . . . . . . . . . . . :  PLCY51FC
Bundle directory . . . . . . . . . :  /u/iburnet/git/cics-perf-workload-dsw-lsr/bu                                           
                                   :  ndles/com.ibm.cics.perf.workload.dsw.lsr.pol

Transaction resource statistics

The following field was added to the collected transaction resource statistics:

Abend count (field XMRAENDC): The number of times that this transaction has abended.

For more information about transaction resource statistics, see Transaction statistics.

Transaction resource class data

CICS monitoring is enhanced with new monitoring records URIMAP and WEBSERVICE in the resource monitoring class. Multiple URIMAP or WEBSERVICE records can be monitored for one task.

The following fields are now available for each URIMAP entry in a transaction resource monitoring record:

MNR_URIMAP_NAME
MNR_URIMAP_CIPHER
MNR_URIMAP_WEBOPEN
MNR_URIMAP_WEBRECV
MNR_URIMAP_WEBSEND

The following fields are now available for each WEBSERVICE entry in a transaction resource monitoring record:

MNR_WEBSVC_NAME
MNR_WEBSVC_PIPE
MNR_WEBSVC_INVK

For more information about fields that are available in the transaction resource class data, see Transaction resource class data: Listing of data fields.
