DriverAvgMsec is wrong on my graphs

[terry....@gmail.com]

Hi

on my san latency graphs, DriverAvgMsec is wrong, its reporting
4000ish and swamping the graph, so we cant see the other 2 categories
which are in the 20-100ms magnitude.

how can i disable this? fix it? delete the history of the broken
reporting?

The SAN latency graphs in 3.5 seems to be a bit odd and I suspect that there's a bug somewhere (haven't narrowed down the source yet). The graphs seems to be much better in 3.0.x.

To disable DriverAvgMsec from being shown, edit /etc/vmktree.conf and change the line:

esxhost.item.d.graphonly:=DriverAvgMsec KernelAvgMsec GuestAvgMsec

into:

esxhost.item.d.graphonly:=KernelAvgMsec GuestAvgMsec

Thanks for that fix.

Latency graphs seems to be a bit weird, i can see hba adapters listed
as well as named FC mount points. Whats the difference between adapter
latency and end point latency.
