I have a sensor that's currently showing total users logged into our systems. It shows 0 to as much as 8000 users logged in daily. I'm green to PRTG, so bear with me. I'm looking to find a way to utilize this sensor to show a drop of 1000 users within two minutes. So far, if I add a threshold trigger below a number, I will get an alarm every night when user access is low.
For example: If I have about 6000 users logged in, then within two minutes it drops to 5000 and stays at that, I'd like to receive an alert.
I have tried to find something with the unusual activity sensor, but i can't see a way to edit it.
I appreciate any help you can give. Many thanks!
