The HTTP Check Receiver can be used for synthethic checks against HTTP endpoints. This receiver will make a request to the specified endpoint using the configured method. This scraper generates a metric with a label for each HTTP response status class with a value of 1 if the status code matches the class. For example, the following metrics will be generated if the endpoint returned a 200:

httpcheck.status{http.status_class:1xx, http.status_code:200,...} = 0
httpcheck.status{http.status_class:2xx, http.status_code:200,...} = 1
httpcheck.status{http.status_class:3xx, http.status_code:200,...} = 0
httpcheck.status{http.status_class:4xx, http.status_code:200,...} = 0
httpcheck.status{http.status_class:5xx, http.status_code:200,...} = 0
