I realize the original post is quite old, but I ran into this today, and figured out how to solve this issue. Thought I'd post the solution in case anyone else stumbles onto this thread.
I am running Snow Leopard on a quad-core iMac. I ran BigTop, for the very first time today. It worked out of the box, and when I started playing around with it, including adding my entire subnet to its host list, it crashed.
After re-launching, BigTop was stuck "Connecting...".
Turns out there is another process, statsCollector, that BigTop relies on for the actual statistics.
The crash left statsCollector running, but useless. The simple solution was to open a Terminal window and execute the following command:
Code:
$ sudo killall statsCollector
(You'll likely be prompted for your password, too.)
Then re-open BigTop, which you can also do from the command line:
Code:
$ open /Developer/Applications/Performance\ Tools/BigTop.app
Viola! BigTop took care of re-launching statsCollector and statistics were once again available. Cool!
Hope this helps someone out.
