2. Configure PRTG Executable Program for notifications: How can PRTG send notifications to Slack?

Setup Instructions

1. Slack Configuration

1. Create a dedicated Slack channel for PRTG notifications (e.g. #prtg)
2. Set up an Incoming Webhook for your Slack workspace
   • Save the Webhook URL for configuration

2. PRTG Configuration

1. Generate a PRTG API Token. Learn how to create the token here: How do I create an API key for Paessler PRTG OPC UA Server

Command Line Parameters

1. Update parameters with your values:
   • Replace SLACK_WEBHOOK_URL with your Slack webhook URL
   • Set SlackChannel to your channel name
   • Update PRTGServer with your PRTG server URL
   • Replace PRTG_API_TOKEN with your generated API token

Use this line in your PRTG notification template Parameters line: Adjust with the above details

-SlackWebHook 'SLACK_WEBHOOK_URL' -SlackChannel '#prtg' -SiteName '%sitename' -Device '%device' -Name '%name' -Status '%status' -Down '%down' -DateTime '%datetime' -LinkDevice '%linkdevice' -Message '%message' -SensorID '%sensorid' -PRTGServer 'https://www.example-prtg-monitor.com' -APIToken 'PRTG_API_TOKEN'

Notes

• There is an if statement in the code that can be changed on what notifications you want to allow.
• If you monitor a bunch of servers Slack can get busy so the if statements exist to help quite things down.
• Change as needed

# Can set one of the if statements to your needs by commenting one or the other out.
# Slack can get busy if you monitor a lot of servers.
# Do NOT send notifications if Name contains excluded terms
#if (-not ($Name -match "APT|Backup|Update")) {
# Only send notifications if Name contains the terms
if ($Name -match "HTTP|Load") {

Security Notes

• Keep your API Token and Slack Webhook URL secure
• Use HTTPS for the PRTG server URL
• Regularly rotate the API Token
