which processes? Have a look at event viewer and tabadmin.log, also are you running low on ram, or cpu, or disk space?
Thanks for the response.
The following are the processes
And i have checked tabadmin.log as well but could not find any.
there is no problem of ram or diskspace.
Yeah, I'm not really sure. Have you opened a support ticket yet?
The alerts are normal. Why do they happen? Talk to your IT department. Maybe they rebooted the server for software/hardware updates? The alerts are just to let you know the Tableau Server was started up/down, it can't know why.
