The Master Console
The master console can control up to 50 collectors. With 30 TSM servers per collector, that gives a maximum of 1500 TSM servers.

In the screenshot below, 8 collectors have been defined to a master console. Each collector controls 30 TSM servers.
One TSM server in Switzerland is not responding (red) and another has an error message (yellow)

The gray top row has a colored symbol that summarizes the state of each collector. Because one TSM server in Switzerland is not responding, the summary status for the collector is red. The summarized collector state will always show the worst condition.
The detail display for the Switzerland collector shows which TSM server is not responding and which one has the error message.
