[Kimchi-devel] [PATCH] Display historical host statistical info on the host tab
Adam King

Thu Apr 24 14:09:04 UTC 2014
Update the host tab statistics graphs to make use of the newly available historical data.
Removed option to continue collecting data while the host tab is out of view, as the server
always has the historcal data available.
