Command return OK when check but Unkonwn on nagios

[amitdaniel]

Hey ,

i created a script that check if some process is running .

Code: Select all

#!/bin/bash

# Nagios return codes
STATE_OK=0
STATE_WARNING=1
STATE_CRITICAL=2
STATE_UNKNOWN=3


while getopts H:u:p:L: OPT
do
  case $OPT in
    "H" ) FLAGH="TRUE" ; HOST="$OPTARG" ;;
    "p" ) FLAGu="TRUE" ; PEM="$OPTARG" ;;
      * ) echo "Usage: $CMDNAME [-H HOST] [-pem /pem/file/location.pem ]. Example: -H 10.0.3.101  -pem /root/x.pem" 1>&2
          exit $STATE_UNKNOWN ;;
  esac
done


# Commands
RESULT=`ssh -i $PEM $HOST 'ps -ef | grep logstash | grep -v grep | wc -l'`


case $RESULT in
[1-2]*)
echo "OK - $RESULT proc found ."
exit $STATE_OK
;;
[0]*)
echo "CRITICAL - $RESULT proc found ."
exit $STATE_CRITICAL
;;
*)
echo "UNKNOWN - $RESULT proc found ."
exit $STATE_UNKNOWN
;;
esac

When i ran this command on /usr/local/nagios/libexec

Code: Select all

./check_logstash.sh -H openx-dist1d -p /root/x.pem

the result is : " OK - 1 proc found . "

i created command like this :

Code: Select all

define command{
command_name check_logstash_virginia
command_line /usr/local/nagios/libexec/check_logstash.sh -H $HOSTADDRESS$ -p /root/x.pem
}

and on nagios UI i get this warning - Status Information: UNKNOWN - proc found .

Some can help me ?

Thanks !!!

Can you try running the command as user nagios?

Code: Select all

su nagios
./check_logstash.sh -H openx-dist1d -p /root/x.pem

[amitdaniel]

Hey

Thanks for your quick replay

when i tried to run the command with nagios user it's looks like the command ignore my pem file

./check_logstash.sh -H openx-dist1d -p /usr/local/nagios/x.pem

nagios@openx-dist1d's password:

But i don't have password.

what should i do ?

Thanks !!!!

./check_logstash.sh -H openx-dist1d -p /usr/local/nagios/x.pem

nagios@openx-dist1d's password:

What are the permissions on /usr/local/nagios/x.pem ?

Code: Select all

ls -l /usr/local/nagios/x.pem

and is /usr/local/nagios/x.pem the same as /root/x.pem that you said was working?

[amitdaniel]

Hey

Thanks again for you very quick response.

Yes the x.pem is the same.

permission are :

-rw------- 1 nagios nagios 1679 Nov 11 17:12 /usr/local/nagios/x.pem

Thanks !

[abrist]

Change the permissions to include the nagios group:

Code: Select all

chmod g+xr /usr/local/nagios/x.pem

[amitdaniel]

Done but now i have other issue

-rw-r-x--- 1 nagios nagios 1679 Nov 11 17:12 /usr/local/nagios/x.pem

[abrist]

Well, heck. Remove the permission:

Code: Select all

chmod g-xr /usr/local/nagios/x.pem

But i don't have password.

what should i do ?

Thanks !!!!

Are you sure your pem is not password protected?

[amitdaniel]

i succeed to run the command using
su nagios

if i ran the command like this

./check_logstash.sh -H root@openx-dist1d -p /usr/local/nagios/x.pem

[amitdaniel]

but still i config the command :

define command{
command_name check_logstash_virginia
command_line /usr/local/nagios/libexec/check_logstash.sh -H $HOSTADDRESS$ -p /usr/local/nagios/x.pem
}


RETURN : UNKNOWN - proc found .
