NET-SNMP DevIO on Solaris

Hi,

I'm trying to create useful graphs out of the Device I/O counters on
Solaris machines. One thing that's noticeable here is that when you
compare Solaris to Linux, net-snmp produces much more useful disk names
for Linux machines:-

snmptable -v 2c -c public localhost 1.3.6.1.4.1.2021.13.15.1
SNMP table: UCD-DISKIO-MIB::diskIOTable

compared to Solaris:-

 snmptable -v 2c -c public localhost 1.3.6.1.4.1.2021.13.15.1.1
SNMP table: UCD-DISKIO-MIB::diskIOTable

 diskIOWrites diskIOReads diskIONWritten diskIONRead diskIODevice diskIOIndex
       492179       79214     1428984320   414330378          sd5           1
            8           4              0          16          sd0           2
            6          10              0          16          sd1           3
      2529381      344693     2042794496  1269037962          sd6           4

Apart from the differences caused by differing Net-SNMP versions and MIB
layout, the device names on Solaris aren't very useful. Unlike Linux
device nodes, where one tends to know which bit of disk they refer to,
Solaris sd* devices correspond to instances of the sd driver, and aren't
the way one normally thinks about disks in a Sun machine.

I can translate them using a small C program:-

./disklist sd
Device Driver Instance Name =      sd0, SVR4 name = /dev/dsk/c1t0d0s0
Device Driver Instance Name =      sd1, SVR4 name = /dev/dsk/c2t0d0s0
Device Driver Instance Name =      sd5, SVR4 name = /dev/dsk/c0t2d0s0
Device Driver Instance Name =      sd6, SVR4 name = /dev/dsk/c0t3d0s0

The code for this is available from Sun at:-

http://access1.sun.com/codesamples/disknames.html

Is there any way I can shoehorn this translation into the agent, so I
get presented with the SVR4 names - either through configuration or by
hacking that short bit of code in? Failing that can it be a feature
request for the next version :-)

Thanks,

Mike
