Feature Request - It would be nice to have a System Update stat so we can see how long the tm1 instance has been running for. It could also be used as a quick indication to if the server has restarted itself (without having to trawl through the tm1server.log to check)
You cannot see from Pulse how long the tm1 instance has been running for but you can see when the TM1 instance has restarted for the last time.
From the Pulse Thick client, you can run the Start up Report, in the example below the last time the CXMD restarted was the 27th of Sep:
To access the reports from the Thick client, you need to go to Tools > Reports:
Then it will ask you to log in with the same password as the Web client.
