Monitoring domain statistics

This section contains the following statistics:

Monitoring domain: Global statistics

These statistics fields are collected from the monitoring domain. They can be accessed online using the EXEC CICS® COLLECT STATISTICS MONITOR command, and are mapped by the DFHMNGDS DSECT. For programming information about the EXEC CICS COLLECT STATISTICS command, see the CICS System Programming Reference manual.

Table 106. Monitoring domain: Global statistics
DFHSTUP name Field name Description
Exception records MNGER is the number of exception records written to SMF.

Reset characteristic: reset to zero

 

Exception records suppressed MNGERS is the number of exception records suppressed by the global user exit (XMNOUT).

Reset characteristic: reset to zero

 

Performance records MNGPR is the number of performance records scheduled for output to SMF.

Because the monitoring domain buffers performance class records, there is still a possibility that monitoring can be deactivated, thus preventing the output of the performance class records that have been buffered.

Reset characteristic: reset to zero

 

Performance records suppressed MNGPRS is the number of performance records suppressed by the global user exit (XMNOUT).

Reset characteristic: reset to zero

 

Resource records MNGRR is the number of transaction resource records scheduled for output to SMF.

Because the monitoring domain buffers transaction resource class records, there is still a possibility that monitoring can be deactivated, thus preventing the output of the resource class records that have been buffered.

Reset characteristic: reset to zero

 

Resource records suppressed MNGRRS is the number of transaction resource records suppressed by the global user exit (XMNOUT).

Reset characteristic: reset to zero

 

SMF records MNGSMFR is the number of SMF records written to the SMF data set.

CICS writes exception class SMF records as soon as the monitor domain is notified of the exception completion, so there is one exception record per SMF record. The performance class, however, has many performance class records per SMF record. The SMF record for the performance class is written when the buffer is full, performance class has been deactivated, or CICS is quiescing.

Reset characteristic: reset to zero

 

SMF errors MNGSMFE is the number of non-OK responses from the request to write a record to SMF. This count is incremented when an SMF write fails for any reason, for example, when SMF is inactive.

Reset characteristic: reset to zero

 

Monitoring domain: Summary global statistics

Summary statistics are not available online.

Table 107. Monitoring domain: Summary global statistics
DFHSTUP name Description
Exception records is the total number of exception records written to SMF.

 

Exception records suppressed is the total number of exception records suppressed by the global user exit (XMNOUT).

 

Performance records is the total number of performance records scheduled for output to SMF.

Because the monitor domain buffers performance class records, there is still a possibility that monitoring can be deactivated, thus preventing the output of the performance class records that have been buffered.

 

Performance records suppressed is the total number of performance records suppressed by the global user exit (XMNOUT).

 

SMF records is the total number of SMF records written to the SMF data set.

CICS writes exception class SMF records as soon as the monitor domain is notified of the exception completion, so there is one exception record per SMF record. The performance class, however, has many performance class records per SMF record. The SMF record for the performance class is written when the buffer is full, performance class has been deactivated, or CICS is quiescing.

 

SMF errors is the total number of non-OK responses from the request to write a record to SMF. This count is incremented when an SMF write fails for any reason, for example, when SMF is inactive.
