Check_SNMP Plugin Problem

[Jones, Stuart]

Hello Kfir,

 

Here is an extract from my setting:

 

check_command        check_snmp!-C public -o ifOperStatus.5 -r 1 -m
RFC1213-MIB ; 1 is up, 2 is down, 3 is testing, 4 is unknown, 5 is
dormant

 

Note the sensor states [1 - 5].

 

 

 

I would suggest you use a MIB browser like iReasoning and check the
states - status prior to locking down your Nagios config file.

 

 

Cheers, Stuart

Subject: [Nagios-users] Check_SNMP Plugin Problem

 

Dear Nagios Team,

 

I am a new user with Nagios.

I am monitoring on of my switches, by using the Check_SNMP Plugin.

 

As explained on your tutorial, the "-r" in the command "check_snmp!-C
public -o ifOperStatus.1 -r 1 -m RFC1213-MIB" refers to the port state
on my switch.

 

the problem is, that although nothing is connected to the port, the
Nagios shows that the port connectivity is OK.

It identifies the port state (1,2,3) but the nagios doesn't show
something is wrong.

 

See below:

 

 

 

 

On the configuration file I configured:

 

# Monitor Ports status via SNMP

 

define service{

       use                  generic-service      ; Inherit values from a
template

       host_name            LAB-C Switch

       service_description  Port 1 Link Status

       check_command        check_snmp!-C public -o ifOperStatus.1 -r 1
-m RFC1213-MIB

       }

define service{

       use                  generic-service      ; Inherit values from a
template

       host_name            LAB-C Switch

       service_description  Port 15 Link Status

       check_command        check_snmp!-C public -o ifOperStatus.15 -r 1
-m RFC1213-MIB

 

 

as I understand from the plugin explanations, the Nagios should identify
that any reply that is other than "1" should indicate an alarm.

 

 

I am using:

Nagios Core 3.3.1

Plugins pack 1.4.15

CentOS Linux

Net-SNMP and Net-SNMP-Utils are installed.

 

 

Your assistance is highly appreciated.

 

Thanks,
