Traffic Monitor for LANs

Is all interlan traffic monitored in the traffic monitor? It doesnt seem so. How to enable this?

Are all the options here ( Technical Features of adam:ONE (v4) anmuscle ) appendable to the anmuscle.conf file? How to use them?

No that traffic is not monitored by default.

You can use the packet-always-monitor-subnets switch.
Backup the config file and add a line that looks like this, replacing the subnets with your own:

packet-always-monitor-subnets=10.0.10.0/24,192.168.5.0/24

restart the muscle.
