RE: Unable to pass on hrStorageSize

Dave,

Thanks for your response.  I was able to get snmpd started properly by modifying the priority for the pass.  A look at the log file showed that both the MIB and snmpd.conf were trying to register the OID at the same time.

Sorry for not including the system information before, this is being put together for a variety of boxes with various versions for both the OS and net-snmp itself.  However, my text box is RHEL 5.8 with Net-SNMP 5.7.1:
# uname -a && snmpd -v
Linux MST-R7-DEV 2.6.18-308.el5 #1 SMP Fri Jan 27 17:17:51 EST 2012 x86_64 x86_64 x86_64 GNU/Linux

NET-SNMP version:  5.7.1

With that said, we had considered modifying the source directly, but discarded this idea as it would require recompiling on upwards of 400 machines that are managed by various different groups.  If I'm mistaken and this can be changed without needing to recompile I would definitely reconsider going this route instead.  Is it possible to make the change without recompiling?

Thanks again,
Sheppy

Quite honestly, I'd be inclined not to tackle it that way.
Instead, why not look at tweaking the code to amend the value
that's being returned?

You don't say which version of the agent you're using, or what O/S
you are using,  but have a look at
    agent/mibgroup/host/hr_filesys.c

(or possibly mibgroup/hardware/filesys/)


That would also avoid your second problem:

That's handled by the agent (not snmpget)
