Sites Monitor allows you to view all your sites health metrics from a single WordPress installation and be in charge of your own data.
Configure a site to act as the “Monitor” (recipient of the data) and synchronise metrics towards it with a interval of your choosing.
Work in progress
This is a early version of the plugin. I have a lot of ideas on how to further improve the plugin and make it something that others might find useful as well. So stay tuned.
