Hello @Kundesaibaba,

1. Dynatrace detects the host abnormality based on AI. So there is no define thresholds you can see. But this can be tweaked base on custom settings at anomaly detection -> host.

Also you can set static thresholds for host abnormality by creating events . see below screenprint.

2. What do you mean by application CI. Can you specify.

Is it host properties or host details?

Checkout Environment v1 API

Cheers!

Question, @RazTN7 . You mention the default threshold for infra anomaly detection is based on AI... did this changed recently? As far I remember, there were a page in old docs that refer to the static thresholds (which I could not find anymore) for the infra anomaly detection. In UI we see them as Automatic, but behind the scene it was using the static threshold as we see when change to "based on custom settings".

So does this works as baseline now?

Thanks.

Hello @dannemca

Yes. Please ref - https://docs.dynatrace.com/docs/shortlink/problem-detection-sensitivity-infrastructure

But the matter of fact I relay on Metric Event when it comes to static alert detection. I dont prefer to change the automatic detection to "Base on custom settings" with static value.

Yes, that's exactly how it works.
@RazTN7 is right 🙂
