You can use baseline conditions to define violation thresholds that adjust to the behavior of your data.
Baseline alerting is useful for creating conditions that:
- Only notify you when data is behaving abnormally.
- Dynamically adjust to changing data and trend s, including daily or weekly trends.
In addition, baseline alerting works well with new applications when you do not yet have known behaviors.
When you choose a data source (for example, an APM metric) for a baseline condition, we'll use the past values of that data to dynamically predict the data's near-future behavior.
The line of that predicted future behavior for that value is called a baseline. It appears as a dotted black line on the preview chart in the baseline condition UI.
You'll use the baseline alert condition UI to:
- Adjust how sensitive the condition is to fluctuations in the data source.
- Set the behavior that will trigger a violation (for example: "deviating for more than five minutes").
- Set whether you want the condition to check for upper violations, lower violations, or both.
When your data escapes the predicted "normal" behavior and meets the criteria you've chosen, you'll receive a notification.

- APM: Application metric baseline
- Browser: Metric baseline
- NRQL (and then choose a baseline type threshold)
Here are some tips for setting baseline thresholds:
- Set the baseline direction to monitor violations that happen either above or below the baseline.
- Set the preview chart to either 2 days or 7 days of displayed data. (Not applicable for NRQL alert conditions.)
- Use the slider bar to adjust the Critical threshold sensitivity, represented in the preview chart by the light gray area around the baseline. The tighter the band around the baseline, the more sensitive it is and the more violations it will generate.
- Optional: You can create a Warning threshold (the darker gray area around the baseline).
- For NRQL alerts, see the allowed types of NRQL queries.
- If the alert condition applies to multiple apps, you can select a choice from the dropdown above the chart to use different metrics. (Not applicable for NRQL alert conditions.)
Here are some details about how the UI works:
