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:
- Inbound Socket Activity bar chart: This compares the current inbound sockets,
the number of inbound sockets created, and the peak number of inbound sockets.
- Outbound Socket Activity bar chart: This 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.
- TCP/IP Statistics table view: This 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.
- TCP/IP Service Statistics table view. This 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 Tivoli OMEGAMON XE for Mainframe Networks V4.1 product is also installed and running, you can link
to its 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).
