Symptom 4: SNMP Agent Port and SNMP Version attributes in the TCP Collector table are blank for all ACTIVE stacks

This symptom indicates that there is a syntax error in the SNMP parameter dataset or that none of the entries in the SNMP parameter dataset has an IP address that matches an address displayed in the IP Address column of the address of a monitored TCP/IP stack.

To correct this problem, edit the TCP Collector SNMP Parameter Dataset and restart the IBM® Z OMEGAMON® AI for Networks agent. A sample of the SNMP parameter dataset named KN3SNMP is stored in &rhilev.&midlev.&rtename.RKANSAMU. Edit this file and copy it to the location that you specified during configuration. For more information about the format of this file, see the SNMP appendix of the IBM® Z OMEGAMON® AI for Networks: Planning and Configuration Guide.

The KN3SNMP file must contain one line for each monitored stack. The IP address specified in each of the lines of the file must be the default home address for the stack. The default home address for a stack is the first address specified in the TCP/IP profile using the HOME statement. The PRIMARYINTERFACE statement can also be used to specify the home address for the stack. See the IBM® z/OS Communications Server: IP Configuration Reference for more information about these statements.

You can also issue this z/OS® console command to determine the home address for a stack:

D TCPIP,tcpipProcName,NETSTAT,HOME

The first address on the home address list displayed with the command is the default home address for the stack.

For more information about the format of the SNMP parameter dataset refer to Format of the SNMP configuration file appendix of the IBM Tivoli® IBM® Z OMEGAMON® AI for Networks: Planning and Configuration Guide.
