CHECK_NRPE WARNING AND CRITICAL ALERT

[InesDiLorenzo89]

Good morning,
I have inserted a script on a windows machine to make check_f5 .
My code is this:

Code: Select all

# Credenziali F5
$user = "*****"  
$pw = "*****"
$hostname = "******" # PROD
$poolNameLike = "*New-Scheduall-Prod*" # PROD
$StatoGREEN = "AVAILABILITY_STATUS_GREEN"
$StatoBLU = "AVAILABILITY_STATUS_BLUE"
$availabilityLike = "*is available*"
$addr="*********"
Try {
   
   Add-PSSnapin iControlSnapin

   $success=Initialize-F5.iControl -HostName $hostname -Username $user -Password $pw
   Clear-Host $success

   $ic = Get-F5.iControl

   # Recupera la lista dei pool
   $pools = $ic.LocalLBPool.get_list()
   $a=0
   
   # Cicla sulla lista dei pool, skippando tutti quelli non "New-Scheduall-Prod*"
   foreach($pool in $pools) { 

       if($pool -notlike $poolNameLike) { continue }
       

       # Lista dei membri con relative informazioni
       $members = Get-F5.LTMPoolMember -Pool $pool
             
           foreach($member in $members) {
            if($member.Address -like $addr) {continue}
            $port = $members.Port 
            $name =  $members.Name
            $availability = $members.Availability
            $enable = $members.enabled
            $status = $members.Status
               if(($member.Availability -eq $StatoGREEN) -or ($member.Availability -eq $StatoBLU)) {
                Write-Host "Service Status" $pool " is ok => " $member.Address                                            #OK             
               } 
                else 
               {
                $a++; 
                Write-Host "Service Status" $pool " is ko => " $member.Address                                #KO     
                                                      
               }
                   
        }
        
   }
   If ($a -eq 0) {
    $exitcode= 0
    Write-Host "No poolmember down"
    Exit $exitcode
    }

    else {
    $exitcode= 2
    Write-Host "Poolmember down"
     Exit $exitcode
    }
  
} Catch [Exception] {
   $exitcode=1
   $err = $_.Exception.Message
   $err
   Exit $a
   }

The command sending is this:

Code: Select all

$USER1$/check_nrpe -H $HOSTADDRESS$ -t 30 -c $ARG1$ $ARG2$

Where $ARG1 check_f5 and $ARG2$ -a 1 2

Unfortunately, however, it does not respect the constraints placed by me or does not go critical and warning .
Thanks so much.

Try setting $ARG2$ to "-a 1 2" rather then just -a 1 2, this may make a difference.

I tried to work on the $ a as the output as numeric but nothing this is the result :

Code: Select all

COMMAND : / usr / local / nagios / libexec / check_nrpe W12PUBPRAS01.sedi.publitalia.dom -H -t 30 -c check_f5 " -a 1 2 "
OUTPUT : 3

Code: Select all

COMMAND: /usr/local/nagios/libexec/check_nrpe -H W12PUBPRAS01.sedi.publitalia.dom -t 30 -c check_f5  -a 1 2
OUTPUT: 3

Nothing changes .
I enclose also the modified code .
The affected part is this:

Code: Select all

Try {
   
   Add-PSSnapin iControlSnapin

   $success=Initialize-F5.iControl -HostName $hostname -Username $user -Password $pw
   Clear-Host $success

   $ic = Get-F5.iControl

   # Recupera la lista dei pool
   $pools = $ic.LocalLBPool.get_list()
   $a=0
   
   # Cicla sulla lista dei pool, skippando tutti quelli non "New-Scheduall-Prod*"
   foreach($pool in $pools) { 

       if($pool -notlike $poolNameLike) { continue }
       

       # Lista dei membri con relative informazioni
       $members = Get-F5.LTMPoolMember -Pool $pool
             
           foreach($member in $members) {
            #if($member.Address -like $addr) {continue}
            $port = $members.Port 
            $name =  $members.Name
            $availability = $members.Availability
            $enable = $members.enabled
            $status = $members.Status
               if(($member.Availability -eq $StatoGREEN) -or ($member.Availability -eq $StatoBLU)) {
                #Write-Host "Service Status" $pool " is ok => " $member.Address                                            #OK             
               } 
                else 
               {
                $a++; 
                #Write-Host "Service Status" $pool " is ko => " $member.Address                                #KO     
                                                      
               }
                   
        }
        
   }
   If ($a -eq 0) {
    $exitcode= 0
     Write-host $a
    #Write-Host "No poolmember down"
    #write-host "The number of user connected  is :"  $a "|'Num_User_RDP'="$a
    Exit $exitcode
    }

    else {
    $exitcode= 2
    Write-host $a
   #Write-Host "Poolmember down"
   # write-host "The number of user connected  is :"  $a "|'Num_User_RDP'="$a
     Exit $exitcode
    }
  
} Catch [Exception] {
   $exitcode=1
   $err = $_.Exception.Message
   $err
   Exit $a
   }

I am reading other posts I tried to change the command to launch the powershell and even powershell code.

FILE NSC.INI

Code: Select all

check_f5=cmd /c echo scripts\check_f5.ps1;  exit($exitcode) | powershell.exe -Version 2 -command -

A PART OF POWERSHELL

Code: Select all

  If ($a -eq 0) {
    $exitcode= 0
    Write-Host $exitcode
     }
    else {
    $exitcode= 2
    Write-Host $exitcode
     }

But nothing change! Any ideas?

[rkennedy]

Maybe I'm missing it, but where are you taking in the inputs for your powershell script? I don't see a place where you are defining what $1 and $2 will represent. You're setting $a to 0.
