after upgrade from ML to Mavericks, open activity monitor, it wont show any process info, even you change to other tab; if you click view - all process, activity monitor will now show all the information that it normally shows🙂, but, after you change to other tab CPU - Memory - Disk etc. all the process information just disappear😮.
anyone facing this problem?😕
MacBook Pro, OS X Mavericks (10.9)

I can it to show processes after changing away from All Processes to something else then back again.. However only CPU information is shown, no memory, network, Disk or energy.. everything 0's

..And all of a sudden.. its now working after leaving my MacBook alone for a wee while...
yep, or reboot mac and run acrivity monitor again, it all fixed😝
I came across this same issue just now except it was only showing me information under the "Energy" tab. I hope this gets fixed soon. In the mean time, I'll reboot to fix it temporarily.
EDIT: Went back to the Activity Monitor right after I posted this and everything was back to normal. Maybe a bug related to App Nap? We shall see.
No need to reboot. For me this problem arises when I switch to Energy tab and then back to other tabs. I noticed, that it can be fixed by changing view style, e.g., by selecting View->All Processes (even it shows that as already selected).
When changed to Energy tab, the view is set to "Applications in last 8 hours", but that option is disabled in all other tabs, so the issue seems to be with setting back to correct view (event it shows as selected, it's not).
Activity Monitor won't show any
