Anyone know some monitoring tool?

<p>I&#39;d need something that i can run e.g. on google app engine. Function is pretty simple, just check that some defined URLs return http status 200 and send some mail if not. Some statistics, like when which page was checked last would be great. I think you get the point.</p> <p>And yet another question: does there exist a free plan on google app engine for go projects? Seems to be hard to get informations about this.</p> <p>Thanks</p> <hr/>**评论：**<br/><br/>Redundancy_: <pre><p>You could probably set up something simple and very cheap using AWS lambda + SNS</p></pre>soapysops: <pre><p>You should use stackdriver monitoring for something like this.</p> <p>There is a free plan for Go on App Engine. It&#39;s part of the Google Cloud wide Free Tier. Check out <a href="https://cloud.google.com/free/" rel="nofollow">https://cloud.google.com/free/</a> for details.</p></pre>tomarus: <pre><p>I wrote <a href="https://github.com/tomarus/minimon" rel="nofollow">minimon</a> a couple of years ago, it&#39;s a really simplistic monitoring tool supporting most Nagios plugins. No idea if that will run on appengine though.</p></pre>
