Problem with a own check. what Log activate for see problem?

[redesgtt]

Hi,

When I run check manually, shows:
[root@nagiosxi nuestros]# ./check_snmp_eigrp.sh ralicante
OK: eigrp neighbor ALC (87) VPB (81)

But when I add this check to "Services", the result in Nagios is bad:
OK: eigrp neighbor ALC (0) VPB (0)




Well, I have tried to see in Nagios.log , but it doesn't show nothing, neither in /var/log/message.

I am pretty sure, there is a problem with file permissions or something. But I don't know where I could see a good log, or activate some log

I would like activate some log to see how Nagios XI (nagios core) runs this check, for see the difference between how I do it and how Nagios does it.

thanks
regards

There isn't really a log for that sort of thing. Can we see the full Nagios service's check_command definition you are trying to use for this service check?

Can we also see the Nagios command definition for check_snmp_eigrp?

command definition:

Code: Select all

define command {
       command_name                             check_eigrpnei_snmp
       command_line                             /usr/local/nagios/etc/nuestros/check_snmp_eigrp.sh $HOSTNAME$
}

script permissions:

Code: Select all

-rwxrwxr-x. 1 apache nagios   1183 nov 10 12:55 check_snmp_eigrp.sh

define service:

Code: Select all

define service {
        host_name                       ralicante
        service_description             Cantidad EIGRP
        use                             Service_Router_10
        check_command                   check_eigrpnei_snmp!!!!!!!!
        process_perf_data               1
        register                        1
        }

Service template:

Code: Select all

       notification_options                     c,r
       notifications_enabled                    1
       register                                 0

}

Like I told you, if I run script manually, it runs. But when I add it to one service, it doesn't run.

You'll want to update your command check_eigrpnei_snmp and add $ARG1$ -

Code: Select all

define command {
       command_name                             check_eigrpnei_snmp
       command_line                             /usr/local/nagios/etc/nuestros/check_snmp_eigrp.sh $HOSTNAME$ $ARG1$
}

Then at the service level, set $ARG1$ to ralicante
(this is what you appear to be passing on the CLI, and not at the Nagios layer.)

Hi, I am sorry for reply you so late.

Well, I have done you said me:
Put argument in command line. Altough I don't understand you said me this, becasuse "Hostname" is "ralicante" too

captura1_problema_check_eigrpnei.jpg

I add "ralicante" such as $ARG1$ in service:

captura2_problema_check_eigrpnei.jpg

and when I apply changes, services status shows:

captura3_problema_check_eigrpnei.jpg

but when I run check with the new "path"

[root@nagiosxi nuestros]# ./check_snmp_eigrp.sh ralicante ralicante
OK: eigrp neighbor ALC (87) VPB (80)


is it possible the problem is I run manually the check how "root" and when Nagios runs via Web-UI with other user?

[rkennedy]

Ah - didn't realize that was the hostname.

What happens if you run it over the CLI as the nagios user? su - nagios and then ./check_snmp_eigrp.sh ralicante (from the appropriate path)

[redesgtt]

it runs OK:

[root@nagiosxi nuestros]# su - nagios /usr/local/nagios/libexec/nuestros/check_snmp_eigrp.sh ralicante
Último inicio de sesión:lun feb 6 12:30:49 CET 2017en pts/0
OK: eigrp neighbor ALC (87) VPB (78)

[tgriep]

Can you post the plugin here so we can view it and see how it is written?

Code: Select all

/usr/local/nagios/libexec/nuestros/check_snmp_eigrp.sh

[redesgtt]

Please, close this thread.

The problem is that script have "plink" for send commands to routers, like:
/usr/local/bin/plink -l $USR -pw $PWUSR "$1" "$2"
(We have it in Nagios Core)

but we have needed put:
sudo /usr/local/bin/plink -l $USR -pw $PWUSR "$1" "$2"
(in our Nagios XI)

We have "plink" in sudoers and in the rest of things that we think "plink" needs stay, but until we didn't put that, script didn't run.

thanks for your support.

Glad to hear you were able to solve it!
