Munin VS PADD

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.

Yeah, I was thinking about making a PiHole version this weekend. But in the meantime, there's also PADD which does something similar for PiHole :)

Looking at https://github.com/pi-hole/PADD/blob/master/padd.sh - the value of $cpu is likely not set correctly. Check for the directories, files and logic that is being used to set it - lines 164 to 172. You could add a 'set -xv' before line 164 to see the output of these commands as the script runs.

Pi-Hole has the PADD project that displays app + system info on the console.

There is a note here about it being run in a loop and a bug report here about the screen only updating and not being cleared so it may be the execution method or something outside the application clearing the screen (either with a clear or scrolling the data off the screen).

PADD is probably written to fit whichever screen mode it's set to, but that definitely appears to be a 4:3 ratio one, which is a pretty normal default that can likely be changed to better fit the screen. If you change the console display mode, there's a good chance PADD will try to fit that. If it doesn't, if for example PADD switches away from a mode that fits your entire screen, that'd be a good thing to report to the author on the GitHub page for PADD.
