Computer Added trigger to email machine information when installed

We've got a trigger set up that emails us when a new access client is installed:
Event.EventType = 'CreatedSession'

However, the CreatedSession event occurs immediately when a session first calls back to the server, so has very minimal information (the Session.SessionID, and that's it).

We'd like to see more detail being fed back on that EventType.:

- {Session.SessionID}: The unique ID of the session in GUID (Globally Unique Identifier) format

- {Session.GuestSystemMemoryAvailableMegabytes}: The available system memory on the guest machine, in megabytes
- {Session.GuestClientVersion}: The version of client software on the guest machine, in N.N.N.N notation
- {Session.GuestNetworkAddress}: The network address of the guest machine, usually in N.N.N.N IPv4 notation
