Munin VS lighttpd-external-munin-proxy

I rediscovered Munin. To my surprise it is written entirely in Perl. I remember Munin from years ago... it still seems healty and maintained and lies ready on your Deb-Repositories. So I followed the Easy Install Guide... which really is easy, but fails to mention that you need to install your own HTTP-Server to serve the HTML-reports.

A bit of background, which may make understanding my choices in this lib easier: Munin is a resource monitoring tool using rrdtool, usually run in a Server/Client Setup. The client accepts plugins which are just executables in a directory. Usually written in a scripting language, but it actually doesn't matter. Data is fetched every 5 minutes, plugins are first run with a config argument to spit out a munin graph config, followed by a run without arguments to present data. To support higher resolutions than just "every 5 minutes", graph config can contain config to tell munin one collects it every second. Then the fetching part needs to run as a daemon, writing a cache somewhere which gets output when munin wants the data.

When you do not have enough power you would get errors because looking up the plots would simply fail. Sounds more that there is one disk which is slower. I had one 2TB external usb which was really slow and the latency of lookups was through the roof. Are you on linux ? Then install munin-monitoring.org it shows latency of the disks out of the box.

what os ? on linux install https://munin-monitoring.org/ it will give you disk latency information.

I'd say give Munin a try.

Munin plugins for monitoring Pi-hole®. Transforms a server into a powerful monitoring platform, as simple as one, two, three, ...four.

munin-pihole-plugins is a set of Munin plugins for monitoring various Pi-hole stats, and now also an installation and management script for deploying the Munin monitoring environment and a lighttpd proxy as well as the plugins themselves. Born of personal use, it has developed into a hobby project of mine.

My lighttpd proxy configuration pertaining to Munin is located here.

How do I install munin-pihole-plugins? Installation of munin-pihole-plugins is covered in the linked repository. Installation of Munin itself, and lighttpd proxy configuration, is handled in my equally creatively named repository lighttpd-external-munin-proxy.

I have a lighttpd proxy config on my GitHub here, and Munin plugins for monitoring Pi-hole on my GitHub here.
