Nagios Support Forum

Hello,

We're getting an error/Warning message in Nagios XI when executing a custom plugin within NCPA. The plugin/powershell script works fine. We were using it on nsclient with no issues. We recently changed the check over to NCPA. When testing the check, we're getting the warning - C:\Program Files (x86)\Nagios\NCPA\plugins\check_file_age.ps1 : Cannot process
argument transformation on parameter 'minutes'. Cannot convert value "120$" to
type "System.Int32". Error: "Input string was not in a correct format."
+ CategoryInfo : InvalidData: (:) [check_file_age.ps1], ParentCon

When using the run check command, we getting the
[[email protected] ~]$ /usr/local/nagios/libexec/check_ncpa.py -H ******* -t '*******' -M 'plugins/check_file_age.ps1' -q 'args=\\******\Backup_K\ABSPRD\*********$*********\******\LOG\,args=120'
OK - Most recent file was touched 10/4/2021 1:40:15 PM

It's working, but but Still is showing up as Warning

Hi,

Can you try changing from this:

/usr/local/nagios/libexec/check_ncpa.py -H ******* -t '*******' -M 'plugins/check_file_age.ps1' -q 'args=\\******\Backup_K\ABSPRD\*********$*********\******\LOG\,args=120'

to
/usr/local/nagios/libexec/check_ncpa.py -H ******* -t '*******' -M 'plugins/check_file_age.ps1' -q 'args=\\******\Backup_K\ABSPRD\*********$*********\******\LOG\,120'

If that doesn't work please send me the check_file_age.ps1 script.

Thanks

Hello, this time, we got an unknown message when we took out the args=

[********** ~]$ /usr/local/nagios/libexec/check_ncpa.py -H ***** -t '******' -M 'plugins/check_file_age.ps1' -q 'args=\\********\Backup_K\ABSPRD\********$*********\AesopStats\LOG\,120'
UNKNOWN: Error occurred while running the plugin. Use the verbose flag for more details.


This is the check_file_age.ps1 script
param(
[Parameter(Mandatory=$true)][string]$directory,
[Parameter(Mandatory=$true)][int]$minutes
)

$ok = 0
$warning = 1
$critical = 2

$latest = Get-ChildItem -Path $directory | Sort-Object LastWriteTime -Descending | Select-Object -First 1
$timespan = New-TimeSpan -Days 0 -Hours 0 -Minutes $minutes

if (((Get-Date) - $latest.LastWriteTime) -gt $timespan) {
# older
Write-Host Critical - Most recent file was touched $latest.LastWriteTime
exit $critical
} else {
# newer
Write-Host OK - Most recent file was touched $latest.LastWriteTime
exit $ok
}

Hi

OK, the args=120 is correct.

What is happening is the powershell script returns an exitcode of 2 if the file is older than 120 minutes,
and an exitcode of 0 if the file is younger than 20 minutes:
The return codes Nagios recognizes are:
0 for OK
1 for Warning
2 for Critical
3 for Unknown


Does that help?

Thanks
