[Nagiosplug-help] check_snmp is always 'warning' for me, also.

I inserted printf statements into the code to print the stderr string. It
named the problem MIB and the line where there was a problem. The first
one was a recently loaded Nokia MIB. I removed it. The second one was
also a Nokia MIB. I removed all of the Nokia MIBs. Everything works.
Since the check_snmp program doesn't give any feed back, I would look into
using the snmpget program. If it returns error strings to check_snmp, I
think it should do the same for the command line. You may have to use the
-m and -M switches to point it at specific MIBs. Be sure and use text
based OIDs instead of numeric. It will force getsnmp to use the MIB.
Just in case you want to try....
The place I put the printf: (Line 327 in nagios-plugins-1.4.0alpha1,
check_snmp.c )
/* WARNING if output found on stderr */
if (fgets (input_buffer, MAX_INPUT_BUFFER - 1, child_stderr))
result = max_state (result, STATE_WARNING);
Follow this with:
printf("\n%s\n", input_buffer);
The input_buffer gets whatever is waiting in child_stderr. The fgets loads
it into the input_buffer.
I guess you could comment out these lines and skip checking for problems in
your MIBs. It would solve a lot of problems.

Nice catch... Is there a CVS version or the plugins package or anything?
I suppose I'd call this a bug. Now to refresh my own memory on how to vet
all my mibs and ditch the ones that generate complaints.
Thanks,
