NRPE plugin only returns first entry
Posted: Thu Jul 23, 2015 10:20 am
I have a powershell script that checks the total bytes/sec for all of the connected network cards of a server, problem is, when its ran though NRPE it only returns the first entry and its perfdata
Its not a buffer limit or an output limit as it perf data is all at the very end of the string, here is my code-
This is my command in NSC.ini:
And my command in nagios:
When I run it locally in powershell I get the following result:
But when I run it though NRPE I get the following result:
It just ignores the second adapter...
Any thoughts?

Code: Select all

#Get any warning or critical levels
foreach ($arg in $args) {
$split = $arg.split('=')

$crit = $split[1]
$crit = [int]$crit
}
}
#Get all connected network devices
$adapterdevice += Get-WmiObject -Class Win32_NetworkAdapter -filter "NetconnectionStatus = '2'" | Select -expand Name
#Find their names
foreach ($adapter in $adapterdevice) {
$adaptername += Get-WmiObject -Class Win32_NetworkAdapter -filter "Name = '$adapter'" | Select -expand NetconnectionID
}
#Find the total bytes per second
foreach ($device in $adapterdevice) {
#Perfmon doesnt like certain characters
$device = $device -replace "[(]","["

#round up to nearest whole number
$getcount = "{0:N0}" -f $getcount
$adaptercount += $getcount
#Build the output string

$num++
}
$num = 0
#Check if any of them should alert and create perfdata
foreach ($adapter in $adaptercount) {

#Add perfdata to the end of the return
