[Nagios-users] snmpwalk works but check_snmp doesn't

[Athiqur Rahman]

I am trying to monitor the status of my BGP connections on a cisco box.

I can get the status of the connection via

[***@watcher libexec]#snmpwalk -v2c -c public 172.16.0.1
.1.3.6.1.2.1.15.3.1.2
SNMPv2-SMI::mib-2.15.3.1.2.212.12.10.11 = INTEGER: 6
SNMPv2-SMI::mib-2.15.3.1.2.234.13.11.109 = INTEGER: 6

you can see i get state established (6) for both peers 212.12.10.11 and
234.13.11.109

But when I execute using the nagios snmp plugin i get the following

[***@watcher libexec]# ./check_snmp -H 172.16.0.1 -P 2c -C public -o
.1.3.6.1.2.1.15.3.1.2
SNMP OK - No Such Instance currently exists at this OID |

What is the best way to go about monitoring the state of the bgp connection?

thanks

check_snmp doesn't do a walk. You must be very specific to the exact OID you want to check. You'll also need to specify failure criteria if you want to get any kind of alert.

I used the following combination --

define command {
command_name check_bgp_peer_state
command_line $USER1$/check_snmp -H $HOSTADDRESS$ -o .1.3.6.1.2.1.15.3.1.2.$ARG1$ -s 6 -C $USER3$ -l 'BGP Peer $ARG1$ State'
}

define service{
use generic-service
host_name myhost
service_description iBGP-to-othernet
retry_check_interval 3
contact_groups nateng-oncall-network
check_command check_bgp_peer_state!212.12.10.11
}
