Look at these key statistics when diagnosing system problems.
- CM_ITIMEOUTS and CM_LTIMEOUTS
- The number of times
that the Gateway daemon failed to allocate a connection manager thread
to a client application within the defined connecttimeout length
of time.
- CS_IALLOCFAIL
- The
number of times the Gateway daemon has tried and failed to allocate
a pipe to a CICS® server.
- CS_IAVRESP
- The
average time taken (in milliseconds) for a connected CICS server to respond to the Gateway daemon
over the course of this interval.
- CS_ICOMMSFAIL
- The number of times communication with a CICS server has failed after a connection has
already been established, or when there has been a failure with the
link during communication with the server.
- CS_LALLOCFAIL
- The
number of times the Gateway daemon has tried and failed to allocate
a pipe to a CICS server. If
this value is high, consider increasing the LOGONLIM or modifying
the pipe allocation model using the variable CTG_PIPE_REUSE=ONE. For
more details, refer to the value for CSX_LALLOCFAIL.
- CS_LCOMMSFAIL
- The number of times communication with a CICS server has failed after a connection has
already been established, or when there has been a failure with the
link during communication with the server. In EXCI, a pipe was available
but the request failed.
- CSX_IALLOCFAIL
- The
number of times the Gateway daemon has tried and failed to allocate
a pipe to CICS server x.
- CSX_IAVRESP and CSX_LAVRESP
- The
average time taken (in milliseconds) for connected CICS server x to respond to the Gateway daemon.
- CSX_LALLOCFAIL
- The
number of times the Gateway daemon has tried and failed to allocate
a pipe to CICS server x.
- GD_CHEALTH
- The current health
of communications between the Gateway daemon and CICS. For more
details, see Health reporting.
- GD_IAVRESP and GD_LAVRESP
- The average
time taken in milliseconds for the Gateway daemon to respond to API
(ECI, ESI) and XA requests from remote
clients. Successful and failed requests are included. This value is
inclusive of the CICS response time, as provided by the corresponding
CS_IAVRESP statistic.
- WT_ITIMEOUTS and WT_LTIMEOUTS
- The number of times
the Gateway daemon failed to allocate a worker thread to a connection
manager within the defined workertimeout length
of time.
