Nagios Support Forum

Hi everyone! I installed nagios on Centos 6.7 from repository and configured it. But it don't work. I receive warning messages:

Warning: Return code of 127 for check of host 'gate' was out of bounds. Make sure the plugin you're trying to run actually exists.

I checked plugins, they are exist. I try to run it from command line:
[root@gate nagios]# /usr/lib64/nagios/plugins/check_ping -H 192.168.0.25 -w 100.0,80% -c 500.0,100% -p 2
PING OK - Packet loss = 0%, RTA = 0.26 ms|rta=0.265000ms;100.000000;500.000000;0.000000 pl=0%;80;100;0
It works fine... Please help me
I checked plugins permission. This is what it shows:

I'll appreciate any help!!!

Can you post your service definition for one of these failing checks?

hsmith wrote:Can you post your service definition for one of these failing checks?

I have just one service:

define service {
<------>use<---><------><------><------>linux-service
<------>host_name<-----><------><------>bigkiev
<------>service_description<---><------>PING
<------>check_command<-><------><------>check_ping!300.0,20%!500.0,60%
<------>}

Can you also post the host definition for the host bigkiev?

This my host definition:
define host {<->
<------>use<---><------><------>office-linux-server
<------>host_name bigkiev
<------>address><------><------>198.168.0.25
<------>check_period<--><------>24x7

<------>notification_period<--->workhours
<------>notification_interval<->30
<------>contact_groups<><------>admins
<------>register<------><------>1
<------>}

and this my check-host-alive command definition:

# 'check-host-alive' command definition
define command{
command_name check-host-alive
command_line /usr/lib64/nagios/plugins/check_ping -H $HOSTADDRESS$ -w 3000.0,80% -c 5000.0,100% -p 5
}

I believe this is a permissions issue.

To verify, can you try running the following commands and post the result -

Code: Select all

su nagios
/usr/lib64/nagios/plugins/check_ping -H 192.168.0.25 -w 100.0,80% -c 500.0,100% -p 2

I tried to do that you wrote, but I have some issue. When I'm trying to do
su nagios
I received this result
This account is currently not available.
but user nagios exists
id nagios
uid=497(nagios) gid=497(nagios) groups=497(nagios)
I checked file /etc/passwd and find there this row:
nagios497:497::/var/spool/nagios:/sbin/nologin
I think I can't do su nagios, because it was created without shell /bin/bash.

Thank you, rkennedy! I solved my issue. I found out I had wrong permissions on directory /bin. I set permissions 755 and it fixed my nagios.
Thanks man!!!

You're welcome. Glad to see this worked! I'll close this thread out now, but feel free to open another one if you ever need assistance in the future.
