Hello,
I've been digging through the stock mibs included with net-snmp and I've
been having trouble digging out some of the disk I/O stats that I want.
The only thing I could find was the "UCD-DISKIO-MIB" mib, which is marked
as deprecated.
Is there somewhere else I should look? The things I'm interested in
grabbing and then graphing in mrtg and monitoring via Nagios are:
-IOPS ("I/O Operations Per Second")
-bytes/second throughput
I also noticed something in the UCD-DISKIO MIB that claims to show "the
average load of the disk" represented by an integer from 0-100. That
seems interesting, but there's no notes in the MIB as to how that number
is calculated, ie: what represents 100% usage?
Some background, these are PostgreSQL servers running on FreeBSD 4.11 and
I'm needing to pull some info to see what kind of bottleneck I'm hitting
here. Having real IOPS numbers would really help in sizing up the SAN
we're looking to buy.
Thanks!
Charles
