Can I Get A List Of Used Usernames In Of PRTG?

The following script will give you a sortable list of all usernames configured in devices and groups, which can be filtered as necessary. Simply save it as PRTG-GetCredentials.ps1 and execute it in a PowerShell window. The list will look like this:



Note that inherited can also mean "not configured".

Attention You can't retrieve passwords with this. Only configured domains and usernames.

Here's the actual script:

#requires -version 4.0
# ___ ___ _____ ___
#| _ \ _ \_   _/ __|
#|  _/   / | || (_ |
#|_| |_|_\ |_| \___|
#  Credential Lister
###################
#
# What exactly is this? 
###################
# This script shows you all the configured credentials in PRTG (only domain and username).
# This will allow you to discern where a faulty account is stored in case it gets locked due to PRTG
# still using outdated credentials. It will show all types of credentials.
################### 
#
# How does it work? 
###################
# Simply execute the script on your PRTG server and it will show a filterable and sortable list. 
# Depending on the size of your configuration, it may take a while, please be patient. 
###################
#
# How do I configure the script itself? 
###################
# The script doesn't need any configuration.
