#119 5.3.0.1 diskIO mib doesn't expose all variables on linux
I am looking to monitor disk usage (load average per spindle) using the
diskIOLA values. I get these to work in FreeBSD just fine, but linux doesn't
seem to expose them to snmp. The diskio mib is configured in
net-snmp-config --configure-options
'--with-mib-modules=host disman/event-mib ucd-snmp/diskio' '--
with-default-snmp-version=2'
snmpget localhost 1.3.6.1.4.1.2021.13.15.1.1.9.1
UCD-DISKIO-MIB::diskIOLA1.1 = No Such Instance currently exists at this
OID
on a FreeBSD host, it works as expected.
snmpget [host] 1.3.6.1.4.1.2021.13.15.1.1.11.1
1.3.6.1.4.1.2021.13.15.1.1.10.1 1.3.6.1.4.1.2021.13.15.1.1.9.1
UCD-DISKIO-MIB::diskIOLA15.1 = INTEGER: 3
UCD-DISKIO-MIB::diskIOLA5.1 = INTEGER: 2
UCD-DISKIO-MIB::diskIOLA1.1 = INTEGER: 0
is this something that can be made to work in Linux?

What version of our software are you using?
What platform are you on? (i.e. what does 'uname -a' report?)

If you find a way to get this kind of information from Linux
via /proc or similar mechanisms, we'll see whether/how we
can improve the ucd-snmp/diskio code.
However, please note that this mib module is optional and
doesn't have as much attention as the core modules. Patches
most welcome! :-)

Added a patch '1779558 Disk io load average on linux' provide these variables on linux. We have been using if for a couple months on CentOS 4.4. The implementation is similar to FreeBSD.
