# Install NsClient++ and configure it properly for tyour environment in the Veeam Backup Server
# Add the following lines to the nsclient.ini file removing the hash character at the beggining
# /settings/external scripts/scripts]
# check_veeam_jobs = cmd /c echo scripts\Check_Veeam_Jobs.ps1 ; exit($lastexitcode) | powershell.exe -command -
# Copy this script to the %programfiles%\nsclient++\scripts folder and restart nsclient service
# By default this script checks all the backup jobs defined and warns when a job fails or is disabled
# if you don�t want to be warned when a job is disabled, use the -d switch
# if you want to check one specific backup job, use -j switch followed by the Job Name 
# This is a sample of how to add those parameters to the nsclient.ini file:
# check_veeam_jobs = cmd /c echo scripts\Check_Veeam_Jobs.ps1  "-d" "$ARG1$" "-f" ; exit($lastexitcode) | powershell.exe -command -
