Jenkins uptime - how long since last restart

Question

Is it possible to see how long a Jenkins instance/master has been running?

I\'ve tried looking around in \"Manage Jenkins\" but can\'t find it there. I know I could log

Answer 1

Just check the "all system logs" at /log/all - scroll the log to the top.

No need for Groovy scripts.

P.S. But, as pointed out, this option will work only if the restart was recent and the corresponding log entries were not overwritten.
