Coupling facility manager data records
Use this topic as a reference to the format of the 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 lowercase, 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 data contains information for each coupling facility list structure, including the CSQ_ADMIN
structure, that the queue manager could connect to during the statistics interval. 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.
