          <h2>What is HostMon?</h2>

<blockquote>
<p><em>HostMon is a simple web-based host monitor and application dashboard. It can be used to monitor the real-time status of hosts and services running in your homelab environment. In addition to monitoring, HostMon has built-in Wake-On-LAN (WOL) capability, SSH client, real-time ping output and the ability to link to your existing Apache Guacamole installation to remotely control hosts from the within browser.<br />
<br />
The HostMon application is written in javascript and uses a SQLite database backend. -<a href="https://github.com/i12bretro/HostMon" target="_blank">https://github.com/i12bretro/HostMon</a></em></p>
