+# Pulse
+
+## Overview
+
+Pulse is a monitoring and optimization platform for Elasticsearch and OpenSearch clusters. It detects issues, tracks performance, delivers smart alerts, and recommendations to keep your search infrastructure healthy.
+
+The integration ingests Pulse alerts as Datadog Events, enabling teams to centralize alert management, correlate issues with metrics and logs, and streamline incident response.
+
+**Pulse shares the following data with Datadog**:
+
+-   Alert title, severity, and description
+-   Triggered and resolved timestamps
+-   Cluster, nodes, and indices names
+
+By connecting Pulse to Datadog, users gain full visibility into search performance and can respond to issues faster within existing workflows.
+
+## Setup
+
+1. In Pulse, navigate to the **Events & Alerts** tab in your cluster's page.
+
+2. Click **Add destinations** and select **Datadog**.
+
+3. Select your Datadog region from the dropdown.
+
+4. Paste your Datadog API key.
+
+5. Optionally, add tags separated by commas or spaces.
+
+6. Select the alert severities you want to forward (Critical, Warning, and/or Informative).
+
+7. Click **Send test alert** to verify setup.
+
+
+## Uninstallation
+
+1. In Pulse, navigate to the **Events & Alerts** tab in your cluster's page.
+
+2. Scroll down to the Datadog card and click the trash icon in the bottom right corner. 
+
+3. In Datadog, navigate to **Integrations**, select the Pulse tile, and click **Uninstall Integration**.
