Have a look at your clients with isi statistics client   with the following --protocols=smb2,lsass_in,lsass_out --classes=create,delete,file_state --orderby --output  You can certainly add to this as you see fit. Curious why InsightIQ "isn't an option."  It's always an option - get an eval license if needed from your SE.  Remember Isilon is designed to scale out - if you're trying to service a workloadfor your business users that is immutable and driving the cluster CPU to saturation, it's time to scale out.
Hi folks,  we are facing heavy CPU load through our business time. I have read the large perfomance thread and i am Aware of the 1/3 network 1/3 client 1/3 cluster performace layout. But when i see a 6 node cluster is @>95% all the day it is a hard discussion with the client and the network guys....  The specific Cluster is a 6 node x200 OneFS 7.0.2.7 without patches smb2 only. We are providing office file space no media streaming etc.... Right now we try to Monitor with this isi statistics:  HDD stats: isi statistics query --nodes=all --stats=node.disk.xfers.rate.avg isi statistics drive --nodes=all --type=sata  SMB stats: isi statistics pstat --protocol=smb2 isi statistics query --nodes=all --stats=node.clientstats.active.smb2 isi statistics query --nodes=all --top -i 1 --stats=node.clientstats.connected.smb  ifs stats: isi statistics heat --nodes=all --totalby=path  Client stats: isi statistics Client --nodes=all  --oderby=ops  CPU stats: isi statistics System --nodes while true; do clear; date; isi_for_array -s top | grep -A 1 -i 'lwio'; sleep 5;done  What we see is a medium IOPS load on the disks / medium to high queue stats on the disks. We see heavy smb2 stats with pstat. Peaks with 20k ops/sec with 10-13k create ops/sec. At the same time lwio is [NAME] - 350 % on all CPUs.  Can anyone tell me commands to dig deeper ? Besides of that does anyone has a idea which workflow could create such heavy smb2 stats ?  P.S InsightIQ is no option right now    /Sebastian
