That is a vague question.
They offer a few things for you right in the shoreware director (their configuration server). There are quick look tools, event logs, phone status', shoregear switch status, application (like VM) servers status, etc. They also have a system/network monitor package now that monitors the devices and the network they reside on.
There are some other things you can use too, such as log files and command line reporting plus some limited canned crystal reports that show some useful info.
There is also a really handy tool called the Trunk Test Tool which allows you to test trunks (analog, T1, PRI, SIP, etc). It also allows you to monitor calls and keep more detailed records of those calls in log files for easy viewing later.
There are tools available, it depends on what you want to do. In some cases though there could be better tools, such as to watch how many calls were taking lost packets or jitter, etc. But no one really has that except Avaya, and even thiers is not easy to use really.
I hope that helps somewhat.
