Environment: AIX 5.3.

I would like to monitor some AIX servers' I/O usage through SNMP.
Parameters that I'm interested in are read/write KB per disk, page-in/
page-out.

However, AIX's standard SNMP daemon doesn't seem to export information
like this.

I've tried to find a way to make the SNMP daemon export such information.
There isn't a lot of information on this, it seems. But a bit of googling
turned up http://www-941.ibm.com/collaboration...lay/WikiPtype/
VIOS_Monitoring#VIOS_Monitoring-SNMP

However, "it simply doesn't work":
"snmpinfo -md -v" outputs nothing related to what I'm looking for, and no
parameter names containing "xm".

Some people I've chatted with suggested installing net-snmp, but I would
rather not have to compile+install extra software on the servers,
especially when I don't know of it will enable me to monitor I/O
performance values.

Any suggestions/comments?

Forgot to mention that the snmpinfo command terminates with this line on
stderr, after having printed around 800 lines of data:
genErr at position 1

You'll want to ensure that the aixmibd managed MIBs aren't being
excluded in the snmpd(v3).conf and that the aixmibd daemon is active.
I know you'll get paging space info, not sure about I/O stats, but
it's probably included as well.

I turned out that we needed to upgrade our AIXes to the latest maintenance (sub?-)level.

Now, our SNMP daemons are able to export much more information. However, I'm having trouble finding IBM MIBs. E.g., what's the following?:
..1.3.6.1.4.1.2.4.12.8.1.5.1.3.6.1.4.1.2.6.191.6.2 55

I've been trying to find a central place for IBM MIBs, but I haven't succeeded. Does anyone know of some IBM site where IBM MIBs may be downloaded?
