Statistics for diagnosing system problems

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.
