Similar: I like <a href="https://jolokia.org" rel="nofollow">https://jolokia.org</a>, which exposes the JMX Attributes as RESTful calls. It can run as an Agent on any JVM, so any piece of Java software (even closed-source) can be monitored.<p>That being said, not a huge fan of using REST for this purpose as it's quite heavyweight compared to something like SNMP or the raw JMX protocol.
