[pve-devel] [PATCH 1/2] add diskread, diskwrite, netin, netout to ResourceStore grid stats

[Alexandre DERUMIER]

Can't tell for 1500vm, i'm using it with 300vm without network latency. (around 11KB for the json response)

Maybe it is possible to get only values of displayed columns ? (passing columns as arguments in the json request ?)

I'm not an expert with extjs..so..

(also does the refresh of the grid each second with 1500 vm don't use too much cpu in the browser ?)

Answering myself: this is not a problem, because we read the cached data directly from RAM (PVE::Cluster::rrd_dump()).

The question is if we really have users running that many VMs - maybe it does not harm if we add a few bytes - need to do more test on that.
