MuninPiholePlugins

Munin plugins for monitoring Pi-hole (tested with Pi-hole v3.1.4 - https://pi-hole.net)

Plugins

• pihole_queries show the queries rates (total dns queries and blocked queries/ads rates). The daily graph from this plugin should have a curve pace very similar to the one from the Pi-hole web interface.
• pihole_cache shows the queries cache rates (forwarded and cached queries rates)
• pihole_clients shows the unique clients statistics (counter which is resetted every day).

Configuration

The Pi-hole web interface need to be installed in order to have the plugins working (they use the web interface api).

Sample setup for '/etc/munin/plugin-conf.d/munin-node':

[pihole_*]
user root
env.host 127.0.0.1
env.port 80
env.api /admin/api.php
