On the TCPTHRSH display in the TCPID column you can enter the TCP/IP jobname to make it specific as to the resource to monitor.
As is the case with most of the SYSVIEW displays if you put your cursor on a column heading and hit PF1 it will bring up help for that column.
If you enter the SYSVIEW command VARS and from the resulting display enter on the command line SELECT GROUP EQ TCPIP it will show you the available variables the can be monitored.
