IBM SC33-1683-02 - Manual (Page 712)

If an autoinstall terminal logs on again before the expiry of the delay
interval, then the accumulation of statistics continues until the next
interval. At that interval, the accumulation of statistics is restarted.
DBCTL
Whenever CICS disconnects from DBCTL, CICS collects the statistics
covering the whole of the DBCTL connection period.
DB2 Whenever CICS disconnects from DB2, it collects the statistics for the
DB2 connection and all DB2ENTRYs covering the period since the last
interval.
Whenever a DB2ENTRY is discarded, CICS collects the statistics for
that DB2ENTRY covering the period since the last interval.
FEPI nodes
Whenever an installed FEPI node definition is discarded, CICS collects
the statistics covering the installed period since the last interval.
FEPI pools
Whenever an installed FEPI pool definition is discarded, CICS collects
the statistics covering the installed period since the last interval.
FEPI targets
Whenever an installed FEPI target definition is discarded, CICS collects
the statistics covering the installed period since the last interval.
Files Whenever CICS closes a file, CICS collects statistics covering the
period from the last interval.
Journalnames
Whenever an installed journalname definition is discarded, CICS
collects the statistics covering the installed period since the last interval.
Log streams
Whenever CICS disconnects a log stream from the MVS Logger, it
collects the statistics covering the installed period since the last interval.
LSRPOOL files
Whenever CICS closes a file which is in an LSRPOOL, it collects
LSRPOOL file statistics (as well as the file statistics), covering the
period from the last interval.
LSRPOOLs
When CICS closes the last file in an LSRPOOL, it collects the statistics
for the LSRPOOL.
Note that the following peak values are reset at each interval collection:
v Peak number of requests waiting for a string
v Maximum number of concurrent active file control strings.
However, the other statistics, which are not reset at an interval
collection, cover the entire period from the time the LSRPOOL is
created (when the first file is opened) until the LSRPOOL is deleted
(when the last file is closed).
Programs
Whenever an installed program definition is discarded, CICS collects
the statistics covering the installed period since the last interval.
