I just started to use logscape, and I have added my first agent to the master server. But, I see as an AgentID there is a very unfriendly name , how can that be configured and changed?
The AgentId is a combination of the hostname and the port used to connect to the manager - it's not configurable as such, it's descriptive.
If you want to change it, you'll need to change your computers hostname. This link may help. http://windows.microsoft.com/en-us/windows/change-computer-name#1TC=windows-7
However, if you're on a business network, you won't want to do that. What you can configure is the role. The Role allows you to segregate your data and identify the computers used.
