So again this may be a problem MIB, lets move it too
mv /usr/share/mibs/ietf/IPATM-IPMC-MIB /tmp

Then the ./check_snmp_cisco.p is trying to cache data in a directory which doesn't exist so you would need to create it

Code: Select all

mkdir -p /var/nagios_plugin_cache
chown nagios:nagios /var/nagios_plugin_cache

The other check does this now

This is the original check I was trying it shows this now

let's move the last item erroring

Code: Select all

mv /usr/share/mibs/ietf/SNMPv2-PDU /tmp
Lets run this (you had a capital S last time)

Code: Select all

./check_snmp_cisco.pl -H 10.2.8.4 -C public -I GigabitEthernet1/1/21 -s up
Also you may need to put the interface in quotes

Code: Select all

./check_snmp_cisco.pl -H 10.2.8.4 -C public -I 'GigabitEthernet1/1/21' -s up
Finally, can you show me the help for the plugin as I do not have it to look at

Code: Select all

./check_snmp_cisco.pl -h
also, if it is this it looks like the interface flag is -i NOT -I

sooooo

Code: Select all

./check_snmp_cisco.pl -H 10.2.8.4 -C public -i 'GigabitEthernet1/1/21' -s up

earlier when you listed the ports, you did not have a port GigabitEthernet1/1/21 but did have a GigabitEthernet1/0/21

Code: Select all

iso.3.6.1.2.1.2.2.1.2.10150 = STRING: "GigabitEthernet1/1/2"
iso.3.6.1.2.1.2.2.1.2.10151 = STRING: "GigabitEthernet1/1/3"
iso.3.6.1.2.1.2.2.1.2.10152 = STRING: "GigabitEthernet1/1/4"
iso.3.6.1.2.1.2.2.1.2.10201 = STRING: "TenGigabitEthernet1/1/1"
Can you run it with that?

Code: Select all

./check_cisco.pl -h 10.2.8.4 -c public -i GigabitEthernet1/0/21 -s down

Good catch event with glasses on I missed that LOL

root@tgcs017:/usr/local/nagios/libexec# ./check_cisco.pl -h 10.2.8.4 -c public -i GigabitEthernet1/0/21 -s down
GigabitEthernet1/0/21 should not be up
root@tgcs017:/usr/local/nagios/libexec# ./check_cisco.pl -h 10.2.8.4 -c public -i GigabitEthernet1/0/21 -s up
GigabitEthernet1/0/21 up: , LastChanges: (49480) 0:08:14.80, Traffic in : 2600355167 octets, out: 1999632072 octets

Looks like it is working now will add to the Nagios config and see what happens

Thank for all the help

Scott.

Have all the interfaces setup now and all working fine.

This can now be locked as resolved.

Thanks again for all the help :D
