HTTP API

The SITE_NAME pinging API is used for submitting success, failure and job start signals from the monitored systems.

General Notes

All ping endpoints support:

HTTP and HTTPS
HTTP 1.0, HTTP 1.1 and HTTP 2
IPv4 and IPv6
HEAD, GET and POST requests methods. The HTTP POST requests can optionally include diagnostic information in the request body. If the request body looks like a UTF-8 string, SITE_NAME stores the request body (limited to first 10KB for each received ping).

Successful responses will have the "200 OK" HTTP response status code and a short and simple string "OK" in the response body.

Signal Success ("ping")

HEAD|GET|POST PING_ENDPOINT{uuid}

Signals to SITE_NAME that the job has completed successfully (or, for continuously running processes, is still running and healthy). The uuid parameter is unique for each check.

Example

GET /5bf66975-d4c7-4bf5-bcc8-b8d8a82ea278 HTTP/1.0
Host: hc-ping.com

HTTP/1.1 200 OK
Server: nginx
Date: Wed, 29 Jan 2020 09:58:23 GMT
Content-Type: text/plain; charset=utf-8
Content-Length: 2
Connection: close
Access-Control-Allow-Origin: *

OK

Signal Failure

HEAD|GET|POST PING_ENDPOINT{uuid}/fail

Signals to SITE_NAME that the job has failed. Actively signalling a failure minimizes the delay from your monitored service failing to you receiving an alert.

Example

GET /5bf66975-d4c7-4bf5-bcc8-b8d8a82ea278/fail HTTP/1.0
Host: hc-ping.com

HTTP/1.1 200 OK
Server: nginx
Date: Wed, 29 Jan 2020 09:58:23 GMT
Content-Type: text/plain; charset=utf-8
Content-Length: 2
Connection: close
Access-Control-Allow-Origin: *

OK

Signal a Start

HEAD|GET|POST PING_ENDPOINT{uuid}/start

Sends a "job has started!" message to SITE_NAME. This is optional but enables a few extra features:

SITE_NAME will measure and display job execution times
SITE_NAME will detect if the job runs longer than its configured grace time

Example

GET /5bf66975-d4c7-4bf5-bcc8-b8d8a82ea278/start HTTP/1.0
Host: hc-ping.com

HTTP/1.1 200 OK
Server: nginx
Date: Wed, 29 Jan 2020 09:58:23 GMT
Content-Type: text/plain; charset=utf-8
Content-Length: 2
Connection: close
Access-Control-Allow-Origin: *

OK
