How to make Indirect checks

[ziedmahjoub]

You will use a 'service check' to define any check that is not the host check. Two host checks cannot be defined on one host. You can read further about service checks and how to define them here: http://nagios.sourceforge.net/docs/3_0/ ... ml#service

Thanks!

i defined it in the host because i though it'll be like the ping one .

its already in a service definition :

Code: Select all

#'disk_usage' service definition
 define service{
      use                   generic-service
      host_name             ala_pc
      service_description   disk_usage
      check_command         check_nrpe!indirect_check_disk
      }

and its the same status UNKNOWN

Does the indirect_check_disk command work from the CLI?

check_nrpe -H nsclientHost -t 60 -c indirect_check_disk

You will likely want to set this up as a service check that runs underneath of the host, since a host can only have 1 host check.

check_nrpe -H nsclientHost -t 60 -c indirect_check_disk

same output from the CLI :

Code: Select all

/usr/local/nagios/libexec$ ./check_nrpe -H 192.168.0.100 -t 60 -c indirect_check_disk
No handler for command: indirect_check_disk

i didn't understand what you want to say

Do you have the command 'indirect_check_disk' defined on the host you're using as a proxy? Please SSH to 192.168.0.100:

Code: Select all

ssh <user>@192.168.0.100

and run

Code: Select all

cat /usr/local/nagios/etc/nrpe.cfg

Please show the output of the above to us. Thank you!

i added this line in the 192.168.0.100 :
indirect_check_disk=scripts\check_disk.bat 192.168.0.25

it still unknown but the status information : no handler for indirect_check_disk is gone.

and run

Code: Select all

cat /usr/local/nagios/etc/nrpe.cfg

the server proxy that i'm using as a is windows server 2008 , that command doesn't work.

i think now the problem is that i dont have the script check_disk.bat in the server that i'm using as a proxy

Hi ziedmahjoub,

part of the problem is that the proxy configuration from 1 version of nsclient++ to the next changed a lot. It looks like you're trying to connect to the indirect host as if it were a Linux box, but it is not correct?

Also, you do not need the check_disk.bat on the nsclient++ proxy since that isn't where you're checking disks. That command only needs to reside on the host which has the disk, but even then it is not necessary because nsclient++ itself (I think you're still monitoring a Windows indirect server right?) has the disk check built in.

[ziedmahjoub]

i'm only checking if the host is alive or not : (

so jdalrymple any solution ?

[jdalrymple]

i'm using NSClient++ 0.4.1.105

Can we get you to upgrade to the current stable, at least on host B? During the 4.1 time the developer was making huge changes to the config syntax and it was poorly documented. The current stuff is better documented.


Before you do the upgrade (if you can) be sure to grab a backup of the entire <c:\program files\nsclient++> directory in case the installer breaks anything that we have to go back to and fix.

If you can't upgrade I'll have to setup a lab with a machine running that specific version to test with. It may even be advisable to speak with the developer about setting up proxying on that version, but I expect he'll just suggest you upgrade too.

[ziedmahjoub]

ok jdalrymple i upgraded it , and when i saw it there is no [/settings/external scripts/scripts] section .

do you want to see the config file ?

In Box293's guide, this section will add the missing settings in your INI file. Did you run this on the host that the Nagios system can access?

Open a command prompt with Administrator rights and type the following commands:

cd "\Program Files\NSClient++\"

nscp settings --activate-module CheckExternalScripts --add-defaults

nscp settings --path "/settings/NRPE/server" --key "allow arguments" --set true

nscp settings --path "/settings/external scripts" --key "allow arguments" --set true

nscp settings --path "/settings/external scripts/scripts" --key check_ping --set "scripts\\check_ping.bat $ARG1$"

Then restart the NSClient++ service

nscp service --stop
nscp service --start

You could post your ini file if you like.
