Command HOST_NAME Macro

[sistemasproadata]

Hi, i have this command defined :

$USER1$/check_nrpe -H 172.18.0.67 -t 30 -c veeam_estado -a $HOSTNAME$

the macro $HOSTNAME$ is not returning me the name defined on the host cfg:

define host {
host_name srvcon003.proa.com
use xiwizard_windowsserver_host

someone knows why?
Thanks

Hello, @sistemasproadata.
Can you show us how you defined the command veeam_estado?

In addition to the NSClient/NRPE command definition, It might also be worthwhile to know which version of Nagios XI you are using as well as the NSClient/NRPE version.

I didn't have any issues passing $HOSTNAME$ in a command definition on Nagios Core 4.3.2 which makes me think this is an issue with the agent's setup:

Code: Select all

define host{
        use                     linux-server
        host_name               PRODHERMES1
        address                 17.212.19.8
        check_command                   check_ping!1000.0,50%!2000.0,80%
}

define service{
        use                             elasticsearch-prod         ; Name of service template to use
        hostgroup_name                  HERMESPROD
        service_description             Hermes Front-end on 7777
        check_command                   test_macros_host
}

define command{
        command_name    test_macros_host
        command_line    echo $HOSTNAME$ is the hostname && exit 0
}

Code: Select all

servicestatus {
        host_name=PRODHERMES1
        service_description=Hermes Front-end on 7777
        check_command=test_macros_host
        plugin_output=PRODHERMES1 is the hostname
        }

@sistemasproadata, Your command definition seems right. Can you upload the veeam_estado.ps1 script here, or send it to me in a PM? That way I could actually test it on my system to see what's going on.

hi, is a simple code to check if one virtual machines is copied on the last veeam backup, the problem is not sending the name of the server as arg, is sending "$HOSTNAME$" as text

Code: Select all

asnp VeeamPSSnapin

$VMName = $args[0].Split(".")[0]
foreach($Job in (Get-VBRJob))
{
   $Session = $Job.FindLastSession()
   if(!$Session){continue;}
   $Tasks = $Session.GetTaskSessions()
   $returncode= 0
$estado= $Tasks | ?{$_.Name -eq $VMName} | %{$_.Status}

   if ($estado -eq "Success")
                     {
                        $returncode= 0
                        write "$estado|$returncode"
                        exit $returncode
                     }
 if ($estado -eq "Warning")
                     {
                        $returncode= 1
                        write "$estado|$returncode"
                        exit $returncode
                     }
}

@sistemasproadata, I did run a test. I added the command just like you have it.

Code: Select all

[/settings/external scripts/scripts]
veeam_estado = cmd /c echo scripts\\veeam_estado.ps1 $ARG1$; exit($lastexitcode) | powershell.exe -command -

I changed the Powershell script to this:

Code: Select all

$VMName = $args[0].Split(".")[0]
Write-Host "passed argument: $VMName "

Then I created a service that uses the following command:

Code: Select all

$USER1$/check_nrpe -H 192.168.3.231 -c veeam_estado -a $HOSTNAME$

I called the host: "srvcon003.proa.com"

Here's the output i'm getting:

Code: Select all

passed argument: srvcon003

So the macro does work. Maybe the problem is that it splits the hostname and only uses the first part before the period?

Hi, my problem is the macro $HOSTNAME$ is sending me the name of the nagios machine, not the hostname defined on the nagios conf for the host.

[[email protected] ~]$ /usr/local/nagios/libexec/check_nrpe -H 172.18.0.67 -t 30 -c veeam_estado -a $HOSTNAME$
passed argument: srvmanmon002

srvmanmon002 is the hostname of nagios
