Check wildfly-uptime

Overview

This check plugin monitors the uptime of a WildFly server, using its HTTP-JSON based API (JBossAS REST Management API). This allows us to monitor the application server without any additional configuration and installation - no need to deploy WAR-Agents like Jolokia. The plugin supports both standalone mode and domain mode.

Tested with WildFly 11 and WildFly 23+.
