Now I had a hardware error which after fixing required a restart.
Unfortunately a raft of servers did not start. Actually I reset the machine later and it is still an issue.
Fortunately, just from a webmin login its easy & quick enough to scroll down and start those stopped/not started servers manually.
Now maybe its there somewhere buried in the webmin menus, but I am trying to avoid ssh in and searching the logs. So is there a log viewing built into webmin somewhere ?
