Time-series data that is stored in the MetricBase database can trigger Workflow Studio flows. These
triggers can log incidents, send emails, and create other alerts.

## Overview of implementing triggers {#metricbase-triggers__section_yxs_bdq_23b}

A trigger definition is a set of conditions that automatically executes a Workflow Studio flow. When you create a trigger definition in MetricBase and associate it with a flow, the trigger definition transfers from your instance to the MetricBase server. After you activate the trigger and flow, MetricBase monitors time-series data in the MetricBase database. When time-series data matches the initial triggering condition, and then transitions from one condition to the next, a transition trigger is generated and added to the queue. The instance
polls the queue, processes the transition trigger, and then executes the Workflow Studio flow.

For more information about time-series policies, see [Create a time-series definition in MetricBase](https://servicenow-prod.fluidtopics.net/LmxlPODtu7ShH6unH1vspA "Specify the metric that you want to store, how often to collect it, and how long to store it in MetricBase.").

   [Create a MetricBase band trigger](https://servicenow-prod.fluidtopics.net/cB7JBgfaJsYJLlgC7fLItA "Create a MetricBase band trigger that detects when a metric value falls within a range of values.")
   :   Triggers when a metric value falls within a range of values.

   [Create a MetricBase linear predictor trigger](https://servicenow-prod.fluidtopics.net/Pk5fWH0GrmTcGzmHdmLD3Q "Create a MetricBase linear predictor trigger to detect when a metric is likely to cross a specified threshold within a specified period of time.")
   :   Triggers when a series of values trend toward and are expected to reach a specified value.

   [Create a MetricBase gap trigger](https://servicenow-prod.fluidtopics.net/c6jOtlKAnctCTSXklEeDmQ "Create a MetricBase gap trigger to alert you when MetricBase stops receiving data.")
   :   Triggers when values are not received for a specified period.

   [Create a MetricBase model trigger](https://servicenow-prod.fluidtopics.net/hfwf67rL4~KNg2GWjvlF5Q "Model triggers execute when the time-series data deviates from expected values.")
   :   Triggers when a trained model detects anomalous behavior.
2. [Execute triggers conditionally](https://servicenow-prod.fluidtopics.net/WizCHhWwLl0KkDjJVFqIxw "MetricBase triggers execute based on a single metric. Condition Scripts impose additional requirements that determine whether a trigger kicks off a flow.")

   Create a trigger condition to add additional requirements for a trigger to execute a flow. For example, data often fluctuates over time. Small fluctuations can cause unwanted,
   duplicate triggering events. A Condition Script can prevent that erroneous duplication.
3. [Assign a trigger to a flow](https://servicenow-prod.fluidtopics.net/vsq69MLtx2Gtg1FT3WVbow "Now that you created a trigger, use Workflow Studio to specify the flow a trigger executes. The flows can provide alerts for unexpected behavior.")

   Associate the trigger with the flow it executes using Workflow Studio.
4. Test the trigger and workflow.
5. Activate the trigger.

## Deleting triggers {#metricbase-triggers__section_zhp_mpw_zhb}

If a trigger is associated with a flow, you can't delete it in MetricBase. To delete a trigger, you must first delete the flow in
Workflow Studio and then you can delete the trigger in MetricBase.

## Legacy triggers {#metricbase-triggers__section_ijj_tnm_ddb}

Legacy triggers are deprecated. You can't create legacy triggers; you can only carry
forward legacy triggers that exist.
