TCPIP Statistics workspace
The TCPIP Statistics workspace is used to monitor the activity of your
CICS regions' TCP/IP connections. The statistics report the volume of inbound
and outbound activity. These statistics can be accessed online using the EXEC
CICS COLLECT STATISTICS TCPIP command.
You can use this workspace to warn you when the MAXSOCKETS value is being
reached by comparing the Maximum sockets limit with the Current inbound and
outbound sockets. Alternatively you can set a threshold to warn you when the
number of times that MAXSOCKETS has been reached or if any timeouts have occurred
while at MAXSOCKETS.
The predefined TCPIP Statistics workspace contains the following views:
- The Inbound Socket Activity bar chart compares the current inbound sockets,
the number of inbound sockets created, and the peak number of inbound sockets.
- The Outbound Socket Activity bar chart compares the current outbound sockets,
current persistent sockets outbound, the number of outbound sockets closed,
the number of outbound sockets created, the peak number of outbound sockets,
and the peak number of persistent sockets outbound.
- The TCP/IP Statistics table view displays maximum number of sockets available
and reports current and peak number of sockets in use for both inbound and
outbound activity. It also reports current and peak number of persistent sockets
in use for both inbound and outbound activity. To help monitor the performance
of your system it reports the number of times at MAXSOCKETS, the total, current
and peak number delayed at MAXSOCKETS, and the total and current delay time
at MAXSOCKETS. The SLSCache setting, and the current active SSL sockets and
the maximum number of SSL TCBs is displayed. The average and current MAXSOCKETS
delay time is calculated.
- The TCP/IP Service Statistics table view lists the status, the service
open, TCP/IP service IP address, the port number in use, the protocol, the
backlog, the attach time security, SSL type, client authentication, TCP/IP
Service privacy, TCP/IP Service WLM DNS group, TCP/IP service prefix, transaction
ID, URM, number of transactions, current and peak number of transactions,
the number of sends and receives, and the number of bytes sent and received
for each TCP/IP service.
If the OMEGAMON XE for Mainframe Networks V4.1 product is also installed and running, you can link
to the Application TCP Listeners workspace. With this feature, you can investigate
the TCP/IP stack, filtered on the Application Name column
(that is, the CICS jobname).
