+### Understand the alert
+
+The Netdata Agent monitors your HTTP endpoints. You can specify endpoints the Agent will monitor in the Agent's Go module under `go.d/httpcheck.conf`.
+The Agent calculates the average response time for every HTTP request made to the endpoint being monitored per hour. The Agent also calculates the average response time in a 3-min window.
+
+The Netdata Agent compares these two (average) values. If there is a significant increase in 3-min average, then it will trigger a warning alert when the response time 3-min average is at least twice as much as 1-hour average. The alert will escalate to critical when the response time 3-min average reaches three times the average amount per hour. 
+
+### Troubleshoot the alert
+
+To troubleshoot this issue, check for:
+
+- Network congestion in your system's network and/or in the remote endpoint's network.
+- If the endpoint is managed by you, then check the system load.
