Architecture

A munin2smartphone setup consists of 3 bricks:

a Munin supervision server.

We add a trigger and a bit of configuration to your stock munin installation, so that it pushes the state of all known checks to the next brick.

a munin2smartphone daemon.

The daemon is receiving authenticated data and generating static web pages.

a frontend to view the web pages.

Whether a web browser or an android widget.
