Activity monitor
As you would expect, the TOS comes equipped with an activity monitor, albeit a fairly rudimentary one. That said, when all it is doing is meant to be giving you a 'general' idea of what is going on with your drive, then do you really care? As you can see from the photos below, you have the option to monitor a variety of operations within the NAS, ranging from CPU activity to all running processes. A note, here, being that it doesn't seem to update that quickly (and this couldn't be changed), meaning that it'll give you a fairly decent, yet infrequent, idea of what's going on with the unit.
