Shared TS queue server: coupling facility statistics

For queues that do not exceed 32K bytes, the data is included in the queue index; otherwise, it is stored as a separate list. The individual fields have the following meanings.

The statistics are described in detail in the DFHXQS1D data area.

Queues: Current S1INDXCT Number of queues currently in existence.
Queues: Highest S1INDXHI Highest number of queues at any time (since last reset).
Index access counts: Wrt adjs S1WRACT Number of index writes to update adjunct area only. (This area contains the read cursor for small queues and the queue status including last used data).
Index access counts: Inquires S1INQCT Inquire on queue index entry
Index access counts: Reads S1RDQCT Read queue index entry
Index access counts: Writes S1WRQCT Write queue index entry.
Index access counts: Deletes S1DLQCT Delete queue index entry.
index access counts: Rereads S1RRQCT Number of index data reads which had to be repeated because the data was larger than the default data transfer size.
Data access counts: Creates S1CRLCT Number of times a separate data list was created.
Data access counts: Writes S1WRLCT Number of queue writes (new or update) for list data.
Data access counts: Reads S1RDLCT Number of list data reads.
Data access counts: Deletes S1DLLCT Delete list (1 per overall delete).
Data access counts: Rereads S1RRLCT Number of list data reads which had to be repeated because the data was larger than the default data transfer size.
Data access counts: Rewrites S1RWLCT Rewrite list entry.
Data access counts: S1INLCT Inquire on list entry
Response counts: Asynch S1ASYCT Number of asynchronous requests.
Response counts: Unavail S1RSP9CT Structure temporarily unavailable, for example during rebuild.
Response counts: Normal S1RSP1CT Number of normal responses.
Response counts: Timeout S1RSP2CT Request timed out by the CF and should be restarted.
Response counts: Not fnd S1RSP3CT Specified entry (queue or item) was not found.
Response counts: Vers chk S1RSP4CT A version check failed for an entry being updated, indicating another task had updated it first.
Response counts: List chk S1RSP5CT A list authority comparison failed, usually indicating big queue was deleted.
Response counts: List full S1RSP6CT Maximum list key reached, indicating max queue size or max queues reached depending on list.
Response counts: Str full S1RSP7CT The list structure is out of space.
Response counts: I/O err S1RSP8CT An IXLLIST return code occurred other than those described above.
