A Slack Slash Command using Powershell Azure Functions

7 minute read

In my previous post I talked about creating a Powershell function to lookup terms in a large internal glossary I had collated. This post takes this a step further and creates a custom slash command integration in a Slack chatroom that calls out to a Powershell-based Azure Function to query my (now) Azure hosted glossary.

Cleaning up paused devices from PRTG with Powershell

9 minute read

One of our AWS based products uses auto-scaling and when new instances are deployed a script automatically creates sensors for them in PRTG (our monitoring tool). When the instances are scaled down/terminated there is not a script that automatically removes them from PRTG (in part so that we can temporarily retain the monitoring history). As a result, our monitoring over time can become cluttered with redundant paused devices, so a script was needed to automate the process of clearing those down.
