+On the [check results overview page](/docs/monitoring/check-results/#check-results-overview), select a specific check run to review its results:
+
+* **Summary:** Displays the check target (URL and port), the check state (`success` for passed and degraded runs, or `error` for failed runs), the request status code and the total check run duration.
+
+* **Error details:** If the check failed, the error status code and message log will be shown.
+
+* **Timing phases:** For each request, we capture the following timing metrics:
+  * DNS: Time taken to resolve the hostname to an IP address (if a hostname was provided)
+  * Connect: Time taken to establish the TCP connection (SYN, SYN-ACK, ACK)

+
+## Overview
+
+A TCP check establishes a connection to a specified hostname or IP address and port to verify that the service is responsive. These checks are ideal for monitoring non-HTTP services, such as databases, message queues, and custom applications that rely on TCP connectivity.
+
+## Create a TCP check
+
+* **Create a check:** Click the `+` icon on the sidebar and select **TCP check** from the list. This will open the check creation page.
+
+* **Name & tags:** On the check creation page, choose a meaningful name for the check to easily identify it. Optionally, add one or more tags to further categorize or group the check.
+
+* **The TCP request:** Configure the TCP endpoint to monitor by specifying a **hostname or IP address** (e.g., tcpbin.com or 192.168.1.1) and a **port** (e.g., 4242).
+
+* **Set response time limits:** Define thresholds for marking the check as degraded or failed. This allows you to specify when requests should be considered slow (degraded) or entirely unreachable (failed).
+
+* **Scheduling strategy & locations:** Choose a [scheduling strategy](/docs/monitoring/global-locations#scheduling-strategies) and which [location](/docs/monitoring/global-locations) you would like to run your TCP check from. Please note that [private locations](/docs/private-locations) are not yet supported for TCP checks but will be available soon.
+
+* **Scheduling:** Schedule your checks to run at intervals between 10 seconds (minimum) and 24 hours (maximum).
+
+* **Retries & alerting:** Configure [retries & alerts](/docs/alerting-and-retries) by choosing from Checkly's retry strategies and alert channels, ensuring you’re notified through your preferred methods when an issue arises with one of your TCP checks.
+
+## Update or delete a TCP check
+
+* **Update a TCP check:** To update a TCP check, click the kebab menu (three dots) next to the check on your [main dashboard](https://app.checklyhq.com) and select `Edit`, or click `Edit` in the top-right corner of the check's Reporting page.
+
+* **Delete a TCP check:** To delete a TCP check, use the kebab menu (three dots) on the [main dashboard](https://app.checklyhq.com) and select `Delete`. Alternatively click `Edit` in the top-right corner of the check's Reporting page, scroll to the bottom section, and click the `Delete` button.
