Playing around with node.js made me build a monitoring tool to perform continuous health checks. I have an application running with a status servlet available under a URL like http://example.com/healthcheck. For a healthy system, I get a JSON as response including an attribute result.summary. In case that summary isn’t OK, I want the monitor to send me an email with details. Nothing spectacular, so you’ll find the little piece (of currently untested) code at GitHub.
