Hello All,
Trying to troubleshoot performance problems on our v3170. This is not specifically a NetApp question but if nothing else, the tool I'm using appears to have been written by a NetApp engineer, does that count?
Running nfsiostat on a handful of impacted clients on another network and uploading the results to a timestamped log file served on a web server so I can reach them. I have a script that parses those pages, takes the last timestamped entry from each file (one file for each client), and tallies up a) the average RTT time for all mounts to the vFiler and b) the worst single instance.
Now that I have it all working, the numbers don't believe like I think they should. The clients are adding an entry to each file every minute. I can see that from the timestamps before each entry. But the numbers don't change. Or they change by a few hundredths of a ms. My gather script returns an average that varies only by .01ms or so, and my "worst" figure has been steady for an hour now.
We're running nfsiostat with no arguments. Am I getting real time readings or some average? If average, since when? Is there a way to get real-time?
Hope to hear from you,
Randy Rue
