Hi Folks,

After doing some research and looking through the net-snmp
agent/mibgroup/host code it seems that the net-snmp agent does not report
device status information.


hrDeviceStatus OBJECT-TYPE
SYNTAX INTEGER {
unknown(1),
running(2),
warning(3),
testing(4),
down(5)


I am planning on implementing the code to
1.) Report the Disk Status. My current thought is to do this through API
Calls to get the S.M.A.R.T status. This would display the Disk Status of
SCSI and IDE drives.
2.) Report the RAID (Software Raid) status by parsing the mdstat output.

My questions are

1.) Should I just modify hr_devices.c to invoke my library calls so that
this function is compiled into net-snmp agent. Obvious disadvantage is
creating patches that would need to be propped on each release upgrade.
2.) Create a Shared Library to be run using the dlmod entry in snmpd.conf. I
don't know that this is even possible considering that the agent already
serves the table hrDeviceTable that the hrDeviceStatus is a part of.

Any guidance towards the implementation direction would be appreciated.
