<h1>HTTP API</h1>
|
|
<p>The SITE_NAME pinging API is used for submitting success, failure and job start
|
|
signals from the monitored systems.</p>
|
|
<h2>General Notes</h2>
|
|
<p>All ping endpoints support:</p>
|
|
<ul>
|
|
<li>HTTP and HTTPS</li>
|
|
<li>HTTP 1.0, HTTP 1.1 and HTTP 2</li>
|
|
<li>IPv4 and IPv6</li>
|
|
<li>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).</li>
|
|
</ul>
|
|
<p>Successful responses will have the "200 OK" HTTP response status code and a short
|
|
and simple string "OK" in the response body.</p>
|
|
<h2>Signal Success ("ping")</h2>
|
|
<div class="highlight"><pre><span></span><code>HEAD|GET|POST PING_ENDPOINT{uuid}
|
|
</code></pre></div>
|
|
|
|
|
|
<p>Signals to SITE_NAME that the job has completed successfully (or, for
|
|
continuously running processes, is still running and healthy). The <code>uuid</code> parameter
|
|
is unique for each check.</p>
|
|
<p><strong>Example</strong></p>
|
|
<div class="highlight"><pre><span></span><code><span class="nf">GET</span> <span class="nn">/5bf66975-d4c7-4bf5-bcc8-b8d8a82ea278</span> <span class="kr">HTTP</span><span class="o">/</span><span class="m">1.0</span>

|
|
|
|
OK
|
|
</code></pre></div>
|
|
|
|
|
|
<h2>Signal Failure</h2>
|
|
<div class="highlight"><pre><span></span><code>HEAD|GET|POST PING_ENDPOINT{uuid}/fail
|
|
</code></pre></div>
|
|
|
|
|
|
<p>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.</p>
|
|
<p><strong>Example</strong></p>
|
|
<div class="highlight"><pre><span></span><code><span class="nf">GET</span> <span class="nn">/5bf66975-d4c7-4bf5-bcc8-b8d8a82ea278/fail</span> <span class="kr">HTTP</span><span class="o">/</span><span class="m">1.0</span>
|
|
<span class="na">Host</span><span class="o">:</span> <span class="l">hc-ping.com</span>
|
|
</code></pre></div>
|
|
|
|
|
|
<div class="highlight"><pre><span></span><code><span class="kr">HTTP</span><span class="o">/</span><span class="m">1.1</span> <span class="m">200</span> <span class="ne">OK</span>

<h2>Signal a Start</h2>
|
|
<div class="highlight"><pre><span></span><code>HEAD|GET|POST PING_ENDPOINT{uuid}/start
|
|
</code></pre></div>
|
|
|
|
|
|
<p>Sends a "job has started!" message to SITE_NAME. This is
|
|
optional but enables a few extra features:</p>
|
|
<ul>
|
|
<li>SITE_NAME will measure and display job execution times</li>
|
|
<li>SITE_NAME will detect if the job runs longer than its configured grace time</li>
|
|
</ul>
|
|
<p><strong>Example</strong></p>
|
|
<div class="highlight"><pre><span></span><code><span class="nf">GET</span> <span class="nn">/5bf66975-d4c7-4bf5-bcc8-b8d8a82ea278/start</span> <span class="kr">HTTP</span><span class="o">/</span><span class="m">1.0</span>
