Hi,
You'll be able to view the logs through RTMT (Real-Time Monitoring Tool).
Just install the plugin from CallManager and launch the app. Then browse to Tools > Trace > Trace & Log Central.
Double click on "collect files" and you can specify from here exactly what logs from what servers you want to collect.
Download them to a local drive where you can view them.
