check_snmp to monitor isdn if on cisco?

[Schmitz, Carsten]

Subhendu, all,

Thanks to all who have replied, the input has been really helpful.

For the history books, I managed to get it to work. Using snmpwalk with numeric oid output I got the OIDs (what a neat trick, that'll save me lots of googling).

Tried with check_ifoperstatus but didn't quite get the parameters right. Now I'm doing:

./check_snmp --oid=.1.3.6.1.2.1.2.2.1.8.29 -C community_string -H ip_address

which checks interfaces.ifTable.ifEntry.ifOperStatus.29 (with 29 being an ISDN interface).

Returns 5, which means "dormant" according to Cisco, and that looks just like the piece of information I need.

Thanks,
Carsten

I haven't done anything with this particular MIB - but your OID is 
incomplete for check_snmp.

the base oid should be  .1.3.6.1.4.9.9.26.1.1.1.1.16 (note four 1s between 
26 and 16)

To the base oid you need to append the table index values
namely:
1. demandNbrPhysIf (the ifIndex value of the D channel for the
    neighbor)
2. demandNbrId (a table sequence number)


Also the base oid above - is for RowStatus and does not tell you anything 
about the line being up/down .

The NeighborTable only stores call information.

for the object descriptions...
ftp://ftp.cisco.com/pub/mibs/v2/CISCO-ISDN-MIB.my

What do you want to monitor for the isdn connections?
