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.

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.
