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. + +### Useful resources + +1.
