I've downloaded a plugin check_mssql_health-1.5.19.3.tar.gz
since I would like to monitor a MS SQL Server that I have in-house.
since I'm new to Nagios I not sure what is the next step.
my question is , is untar this file inside /Usr/local/nagios/libexec the only thing needed to work with this plugin ?
I can pretty much lock on my own how to work with the plugins, but can't find how to integrate the plugin with Nagios in the first place
I'm posting this message after 3.5 hours searching on how to do it. and I don;t have the answer yet.
thank you in advance and sorry if this is a silly question.

You have extracted it to the correct location, you're off to a good start.sciencedicas wrote:my question is , is untar this file inside /Usr/local/nagios/libexec the only thing needed to work with this plugin ?
You need to create a command in nagios that uses the plugin. It's easiest to look at an existing command as reference.
In the file:
/usr/local/nagios/etc/objects/commands.cfg
There is a command like so:
Code: Select all
# 'check_ping' command definition
define command{
command_name check_ping
command_line $USER1$/check_ping -H $HOSTADDRESS$ -w $ARG1$ -c $ARG2$ -p 5
}
/usr/local/nagios/etc/objects/localhost.cfg
There is a service definition like so:
Code: Select all
define service{
use local-service ; Name of service template to use
host_name localhost
service_description PING
check_command check_ping!100.0,20%!500.0,60%
}
Now if I compare the command against the service definition:
Code: Select all
$USER1$/check_ping -H $HOSTADDRESS$ -w $ARG1$ -c $ARG2$ -p 5
check_ping!100.0,20%!500.0,60%
Then an exclamation mark is used ! to separate the command_name and $ARG1$
The next value is $ARG1$ (100.0,20%)
Then an exclamation mark is used ! to separate $ARG1$ and $ARG2$
The next value is $ARG2$ (500.0,60%)
What is executed by Nagios is:
Code: Select all
/usr/local/nagios/libexec/check_ping -H 127.0.0.1 -w 100.0,20% -c 500.0,60% -p 5
Code: Select all
PING OK - Packet loss = 0%, RTA = 0.10 ms|rta=0.099000ms;100.000000;500.000000;0.000000 pl=0%;20;60;0
- Test the plugin on the command line first so you know how it needs to be defined
Create a command in commands.cfg
Create a service in the <your_monitored_server>.cfg file that uses the command_name you defined in commands.cfg and supplies the relevant arguments
