TCP/IP: Global statistics
You can retrieve TCP/IP global statistics by using the EXEC CICS EXTRACT STATISTICS TCPIP system command. They are mapped by the DFHSOGDS DSECT.

|
| Peak number of persistent outbound sockets | SOG_PEAK_PERS_OUTB_SOCKETS | is the peak number of persistent outbound sockets. Reset characteristic: reset to current
|
| Total number of inbound sockets created | SOG_INB_SOCKETS_CREATED | is the total number of inbound sockets created. Reset characteristic: reset to zero
|
| Total number of outbound sockets created | SOG_OUTB_SOCKETS_CREATED | is the total number of outbound sockets created. Reset characteristic: reset to zero
|
| Total number of outbound sockets closed | SOG_OUTB_SOCKETS_CLOSED | is the total number of outbound sockets closed. Reset characteristic: reset to zero
|
| Total number of inbound and outbound sockets created | SOG_INB_SOCKETS_CREATED + SOG_OUTB_SOCKETS_CREATED | is the total number of inbound and outbound sockets created. Reset characteristic: reset to zero
|
| SSLCACHE setting | SOG_SSLCACHE | reports whether SSL caching is taking place
locally within a CICS® region, or across a sysplex. Reset characteristic: not reset
|
| Current MAXSOCKETS limit | SOG_MAXSOCKETS_LIMIT | is the maximum number of IP sockets that can be managed by
the CICS sockets domain. Reset characteristic: not reset
|
| Number of times the MAXSOCKETS limit was reached | SOG_TIMES_AT_MAX_SOCKETS | is the number of times the maximum number of IP sockets limit
(MAXSOCKETS) was reached. Reset characteristic: reset to zero
|
| Number of create socket requests delayed by MAXSOCKETS limit | SOG_DELAYED_AT_MAX_SOCKETS | is the number of create socket requests that were delayed because
the system had reached the MAXSOCKETS limit. Reset characteristic: reset to zero
|
| Total MAXSOCKETS delay time | SOG_QTIME_AT_MAX_SOCKETS | is the total time that create socket requests were delayed
because the system had reached the MAXSOCKETS limit. Reset characteristic: reset to zero
|
| Number of create sockets requests timed out at MAXSOCKETS | SOG_TIMEDOUT_AT_MAX_SOCKETS | is the number of create socket requests that were timed out
while delayed because the system had reached the MAXSOCKETS limit. Reset characteristic: reset to zero
|
| Current create socket requests delayed by MAXSOCKETS limit | SOG_CURR_DELAYED_AT_MAX | is the current number of create socket requests delayed because
the system is at the MAXSOCKETS limit. Reset characteristic: not reset
|
| Peak create socket requests delayed at MAXSOCKETS | SOG_PEAK_DELAYED_AT_MAX | is the peak number of create socket requests delayed becuase
the system is at the MAXSOCKETS limit. Reset characteristic: reset to current
|
| Current MAXSOCKETS delay time | SOG_CURRENT_QTIME_AT_MAX | is the current total delay time for the create socket requests
that are currently delayed because the system is at the MAXSOCKETS
limit. Reset characteristic: not reset
|
| Performance tuning for HTTP connections | SOG_SOTUNING | indicates whether performance tuning for HTTP connections will
take place. Reset characteristic: not reset
|
| Socket listener has paused listening for HTTP connections | SOG_PAUSING_HTTP_LISTENING | indicates whether the listener has paused listening for HTTP connection requests because the number of tasks in the region has reached the limit for accepting new HTTP connection requests Reset characteristic: not reset
|
| Number of times socket listener notified at task accept limit | SOG_TIMES_AT_ACCEPT_LIMIT | is the number of times the listener has been notified that
the number of tasks in the region has reached the limit for accepting
new HTTP connection requests. Reset characteristic: reset to zero
|
| Last time socket listener paused listening for HTTP connections | SOG_TIME_LAST_PAUSED_HTTP_LISTENING | is the last time the socket listener paused listening for HTTP
connection requests because the number of tasks in the region had
reached the limit for accepting new HTTP connection requests. The
DFHSTUP report expresses this time as day/month/year hours:minutes:seconds:decimals;
however, the DSECT field contains the time as a store clock (STCK)
value in local time. If the DFHSTUP report shows the date and time
as --/--/---- --:--:--:---- then that indicates that the listener
has never paused listening for HTTP connection requests since the
statistics were last reset. Reset characteristic: reset to zero
|
| Region stopping HTTP connection persistence | SOG_STOPPING_PERSISTENCE | indicates whether the region is stopping HTTP connection persistence
because the number of tasks in the region has exceeded the limit. Reset characteristic: not reset
|
| Number of times region stopped HTTP connection persistence | SOG_TIMES_STOPPED_PERSISTENT | is the number of times the region took action to stop HTTP
connection persistence because the number of tasks in the region has
exceeded the limit. Reset characteristic: reset to zero
|
| Last time stopped HTTP connection persistence | SOG_TIME_LAST_STOPPED_PERSISTENT | is the last time the region took action to stop HTTP connection
persistence because the number of tasks in the region has exceeded
the limit. The DFHSTUP report expresses this time as day/month/year
hours:minutes:seconds:decimals; however, the DSECT field contains
the time as a store clock (STCK) value in local time. If the DFHSTUP
report shows the date and time as --/--/---- --:--:--:---- then that
indicates that HTTP connection persistence has not been stopped since
the statistics were last reset. Reset characteristic: reset to zero
|
| Number of persistent connections made non-persistent | SOG_TIMES_MADE_NON_PERSISTENT | is the number of times a persistent HTTP connection was made
non-persistent because the number of tasks
in the region has exceeded the limit. Reset characteristic: reset to zero
|
| Number of times disconnected an HTTP connection at max uses | SOG_TIMES_CONN_DISC_AT_MAX | is the number of times a persistent HTTP connection was disconnected
because the number of uses had exceeded
the limit. Reset characteristic: reset to zero
