fibre channel throughput

SILO Storagetek — Fri, 20 Feb 2004 10:11:23 GMT

hi everyone,
I've a system with some FC interfaces, and I need to check the global throughput. Is there a perfview metric about it?

tnx
prod.

Hi prod.,

The file
/opt/perf/paperdocs/mwa/C/metrics.txt contains the *entire* list of metrics for perfview.

I don't see an *specifically* for fibre channel, but any of the disk metrics like
GBL_DISK_*
BYDISK_*
or any of the FS metrics
LV_*
or any of the process by disk metrics
PROC_DISK_*
and even possibly the application by disk metrics
APP_DISK_*
if targeted to the proper FC devices should give you what you want.

HTH,
Jeff

I don't know about perfview. Glance doesn't have anything for fibre. You can look at the devstats option of the fcmsutil command, and use it similar to netstat -s where you run at intervals over a period of time, and calculate the delta's between runs to derive a throughput figure.

fcmsutil /dev/td0 stat

That will give you some basic numbers. You can run it during a high i/o stress test.
