Issue/Introduction

Pertaining to the CTCLASS screen:

SYSVIEW VTAM 26AS      CTCLASS, CICS Transaction Classes                                02/05/21 14:54:22

Does the QueTot data value reset at a different time than the rest of these CTCLASS data values? I'm trying to comprehend the reason for the QueTot value in this example. 

Resolution

SYSVIEW does not set these values but reports on them from real-time statistics that are maintained by the CICS DFHXM domain (Txn Manager Domain).  SYSVIEW does not perform its own interval collection for this data.  All of the statistics get reset at the same time, including the QueTot, which happens when CICS cuts stats records based on SIT parms STATRCD= and STATINT=, or a CICS PERFORM STATISTICS, RESETNOW, etc.    

A google search on CICS Statistics Reset shows:   

Statistics counters are reset in the following circumstances: At CICS® startup.
...
Change the statistics recording status, by using one of these options:

1. The Reset Time option of the CICS Explorer® Regions operations view.
2. The CEMT SET STATISTICS ON|OFF RESETNOW command.
3. The EXEC CICS SET STATISTICS ON|OFF RESETNOW command.
