+# Alerting Rule Templates [alerting-rule-templates]
+
+Alerting rule templates are out-of-the-box, preconfigured rule definitions maintained by Elastic integration authors. They help you start monitoring in minutes—no queries to write, no thresholds to figure out—by providing curated {{esql}} queries, sensible defaults, and recommended thresholds tailored to each integration. Templates are available from an integration’s Assets and open a prefilled rule creation form you can adjust and enable.
+
+## Prerequisites
+
+- Install or upgrade to the latest version of the integration that includes alerting rule templates.
+- Ensure the relevant data stream is enabled and ingesting data for the template you plan to use.
+- {{stack}} 9.2.1 or later.
+- Appropriate {{kib}} role privileges to create and manage rules in the current space.
+
+## How to use the Alerting Rule Templates
+
+Alerting rule templates come with recommended, pre-populated values. To use them:
+
+1. In {{kib}}, go to **{{manage-app}}** > **{{integrations}}**.
+1. Find and open the integration.
+1. On the integration page, open the **Assets** tab and expand **Alerting rule templates** to view all available templates for that integration.
+1. Select a template to open a prefilled Create rule form.
+1. Review and (optionally) customize the prefilled settings, then save and enable the rule.
+
+When you click a template, you get a prefilled **Create Rules** form. You can use the template to create your own custom alerting rule by adjusting values, setting up connectors, and defining rule actions.
+
+The preconfigured defaults typically include:
+
+- **{{esql}} query**
+:   A curated, text-based query that evaluates your data and triggers when matches are found during the latest run.
+- **Recommended threshold**
+:   A suggested threshold embedded in the {{esql}} `WHERE` clause. You can tune the threshold to fit your environment.
+- **Time window (look-back)**
+:   The length of time the rule analyzes for data (for example, the last 5 minutes).
+- **Rule schedule**
+:   How frequently the rule checks alert conditions (for example, every minute).
+- **Alert delay (alert suppression)**
+:   The number of consecutive runs for which conditions must be met before an alert is created.
+
+For details about fields in the Create rule form and how the rule evaluates data, refer to the [{{es}} query rule type](/explore-analyze/alerts-cases/alerts/rule-type-es-query.md).
