Review the man page for netmon.
Use the -C <prefix> option for loading netmon. The prefix will be used for
any collections created in the format <prefix><MLM hostname>. Example, use
MLM_ as the prefix and you will get collection names like MLM_hostnameB,
MLM_hostnameC, etc. Then from the command-line, netmon -a 50 will create
collections for your MLMs based on local subnet. Once the collections are
made you can edit them like any other collection. Add the additional
subnets to the collection or any other rule. To check to see if the
collections are working, use netmon -a 102. This will dump the managed
interfaces of the MLMs and the nodes they are monitoring to the netmon.trace
Another option is to use APM, but I had problems with it and support sent me
