Understanding why baseline alert did not fire

###Alerts Question Template

Yesterday we experienced poor web response time for about 30 minutes. I have a baseline alert policy set up to fire whenever we deviate from our baseline for more than 10 minutes but I received no alert.

• Please describe what are you seeing:
  Here is our alert policy:

During that time period, this is what I see from insights:

• How does this differ from what were you expecting to see?

I would have expected to have an alert fire in this situation.

• If you aren’t seeing expected alert or data, please provide a link to the incident or violation (policy, condition, data app etc.)

Hi @Karl11!

Baseline Alerts can be a bit tricky to get dialed in. They require lots of varying data points and a data stream that has been around for about a week in order to function properly.

One thing I see in the preview graph in your screenshot is that the data hugs a tight line. This indicates that this may not be a good candidate for a Baseline alert condition. When a baseline hugs any value, it will cause the baseline prediction to narrow down to that value and cause unwanted results. I would recommend checking out the amazing community post put together by one of our Relic Technical Support Engineers below for more information on Baseline alert use cases.
