Filesystem Bottleneck Monitoring
There are 2 filesystems on my server that are now undergoing some data copying/processing. My team is suspecting that there is some bottleneck there. They are suspecting there's an I/O problem and asked me to turn on some monitoring to tell them if all is ok.
Is there a way to set up some detailed monitoring on what is going on with the performance of the directories? We have the filesystems striped.

Shalom,
If you have glance licensed, you can monitor the i/o of all disk real time, or by collecting glance data to disk.
sar -d is a pretty good tool and you can also set up cron to monitor on that basis.

Includes free monitoring tools, based on sar and a script set HP gave me years ago.

Re: Filesystem Bottleneck Monitoring
Is it a SAN disk or local disk,
with glance as said above you can check disk IO as well as LV wise,
use glance sar to isolate the issue.
Is copying very slow or or smthing.

Re: Filesystem Bottleneck Monitoring
Hello,
In addition, if your filesystems are from SAN, you should check the ports status/traffic made through the SAN switch.
