Glowroot is a lightweighted but feature-rich java VM agent, which will allow you to collect and evaluate metrics from almost any VM. For larger setups, you might want to install a central collection instance. This guide covers how to set up Glowroot Central on OpenLiberty, a lightweigt and extremely fast Java Application Server (aka Servlet Container).
If you are using Apache Guacamole to access your computers via VNC, RDP or SSH, you might be interested on how to run this web application (war file) as Guacamole Liberty Profile Stack (i.e. on IBM Websphere Liberty Profile). Additionally, you can start the IBM server with systemd to see the console logs in journalctl. Although Liberty Profile is a licenced and proprietary product by IBM, it is free of charge for non-production purposes and development.
