Coupling Facility manager data records
The format of the Coupling Facility manager statistics record is described in the following table and in assembler macro thlqual.SCSQMACS(CSQDQEST) and C header file thlqual.SCSQC370(CSQDSMFC). The field names in C are all in lower case, for example qest, qestid.
If the queue manager was not started as a member of a queue-sharing group, no data is recorded in this record.

The information for each structure includes the following:
- The number of and cumulative elapsed times for IXLLSTE and IXLLSTM requests.
- The number of times a request had to be retried because of a timeout.
- The number of times a 'structure full' condition occurred.
