Microsoft Entra Monitoring

Hi guys!
I need to monitor some things in "Microsoft Entra", but I don't know how. I can't find a plugin that does it. I need to monitor the expiration date of customer secrets.

Any help would be greatly appreciated. Thanks!

Hello @cracolo,

There isn't currently a plugin to do this AFAIK, but if you're willing to make your own plugin, you should be able to just query the right Microsoft Graph endpoints with your plugin. There are some steps to get authentication working, but the calling of the API is pretty straightforward. Here are some resources that'll provide the information you need:

MSFT Graph - How to get client secret expiry details through an API
MSFT Graph API Usage Guidelines
MSFT Graph Explorer - A Tool for testing Graph API calls
Nagios Plugin Guidelines - The main thing you need here are just the return formatting
