New feature: Remote monitoring

In the latest release, MAGNAPing received a new optional feature, which simplifies its administration: the remote monitoring. The user can now enter the address of  a host, which runs MAGNAPing, in a browser, and see the status of the instance and the lists of URLs that are being monitored and those that failed.

The monitoring dashboard is a regular HTML file, which can be customized and themed/skinned by the user. Each substitution variable/token in the HTML element belongs to its own class, for styling through CSS.

The built-in HTTP server can be turned off, to conserve resources.
