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 time outs 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.
You can link to the Application TCP Listeners workspace provided by the OMEGAMON® for Mainframe Networks product to investigate the TCP/IP stack, filtered by the CICS Application Name.
