Thanks for info, for now.
I’ve discovered a tool I didn’t
know. LogicMonitor seems really a good tool.
Together with Operation Manager
I remember that also DFM could do the job. Right? So, nothing free (execpt CLI
and lot of values to read on the putty log!! J)
Is there somebody that remember
if the new System Manager can help? I remember that there’s some ‘stats&perf”
area…

Oggetto: Re: High CPU utilizations and file I/O
Not sure if by 'tool' you meant commercial product, but
LogicMonitor certainly does that.
It will discover all the volumes, and which aggregate they are on, and
construct graphs for each aggregate showing IO operations of each volume (as
well as detailed volume graphs showing read, write and other operations/sec,
and throughput, and latency values per volume.)
Plus a lot of other NetApp alerting and monitoring (space/inode per volume,
shelf electronics, spare drives, autosupport success, individual CPU stats,
physical disk utilization, etc).
Let me know if you want more information.

Hi all,
From some days the CPU of a 3020C reaches 100% slowing down all
processes.
Maybe some area of a 3020HA is stressed on I/O.
There’s a VMware on NFS farm using both servers and VDI
also! The customer states that in the NFS volume for VMware there’s an high
activity of continous destruction and building of VMware vdisk…
Is there some tool that can let me understand which volume
is under stress and in case move it on the other head?
Or maybe this filer is undersized for the job that has been
asked…
