#munin — Public Fediverse posts

Applications should re-create the necessary internal directory structure to run instead of logging cryptic error messages in not-obvious log files.

Munin, I'm looking at you!

With your use of /var/lib/munin/cgi-tmp/munin-cgi-graph/ to save temporary files... #linux #munin

Played with an old tool I haven't touched in over a decade. Got munin, munin-node, and plugins installed. Then installed the C version of the node and plugin on several network devices. The C version is specifically written for small embedded device, with low overhead.

The documentation for the C plugin is extremely poor. Took me a while to figure out what symlinks I had to create in /etc/munin/plugins/ to get it working. Attempted to use Gemini and ChatGPT, but both got the answers wrong as they couldn't differentiate between the popular "Perl" Munin node plugins and the C version I wanted to use.

Which made me think -- is there some other open-source tool or framework that has replaced Munin in the last decade since I used it?

I suspect I'll be writing a few plugins. Last time I did that would have been in 2010. #Munin

Fixing MariaDB socket authentication on Debian

For a while, my system users have not been able to connect to a local MariaDB using the Unix socket. I finally sat down and traced a fix down.

tl;dr: `alter user ‘root’@’localhost’ identified via unix_socket;`

I had been playing with Grafana, InfluxDB, Telegraf and Prometheus the last two weeks and can now share my story of what I finally use to replace my Netdata instances and why.

Il y a longtemps, j'étais tombé sur cet article de @luc : https://fiat-tux.fr/2018/04/04/utiliser-les-donnees-de-munin-dans-grafana/ et c'était top.
2026, j'ai migré ma stack sur docker sans pouvoir retrouver l'équivalent et compatible avec un Grafana récent, alors je m'y suis collé 😉 une API qui exporte les données RRD via une API JSON containerisée.
C'est ici que ça se passe :
https://github.com/nioc/rrd-json-exporter
#munin #grafana #rrd #dev

On installe munin et munin-node et tada, on a plein d'infos pour monitorer son serveur debian ou ubuntu.

Vazy faire aussi simple avec #prometheus et #grafana, c'est moi ou c'est ultra relou d'obtenir autant d'infos qu'avec #munin ?

3-2-1 backups with Restic

https://blog.narf.ssji.net/2025/09/29/3-2-1-backups-with-restic/

After many years using Backup Manager, I reached the limits of system load, size, and time needed to create and store incremental backups. I migrated to Restic, which only required a handful of scripts to achieve the same backup schedule in much less time and storage.

#Munin ist ein tolles Tool zum #Servermonitoring, aber das letzte Release ist Jahre her und ein update der Grafik wäre vielleicht nicht falsch.

Aber was meint ihr, für eine neue Serverinfrastruktur: trotzdem einsetzen oder könnt ihr Alternativen empfehlen?

#Server #Admin #IT

@bjoern Ich nutze #munin für die zeitliche Auswertung und #monit für Benachrichtigungen mit #ntfy Ist beides recht einfach aufgesetzt. #monit nutze ich auch um Anwendungen mal neu zu starten wenn die zu viel RAM brauchen oder hängen sollten.

#munin monitoring setup done! ✌️ Was not as straightforward as I expected but it wasn't Munin's fault.

Took me quite some time to figure out that the firewall was blocking access to port 4949 on the #immich server.

Without that Munin was blind. 🐦‍⬛

Yesterday the server was down because the laptop decided to enter sleep (when I’ve told it not to) and this morning it was also offline but it was something else. The fans were full on so it was doing something but I suspect not very useful. Could not bring the display up or switch TTY. Couldn’t even hard reboot. Had to remove the battery. Until I have eyes on the machine there’s not much to say. Planning on setting up #munin.

I’ve changed the #Munin crontab on my #FreeBSD gateway so it computes graphs once every 10 minutes instead of once every 5 minutes. I don’t need super frequent graph updates and I’m trying to control this device’s energy consumption.

The graph below shows 24h of power drawn by this fan-less PC. Before change the average power is around 24W with a dense area between 20W and ~36W.
After change the area turns into a forest of slim lines, and the average power is zigzagging around 22W.

So I am looking for a monitoring system with lowest hardware requirements to run on RPi B+ (single armv6hf core and 512Mb RAM) and monitor home network.
Things tried so far:
1. #Zabbix -- great tool but the server is almost unusable on devices this weak
2. #LibreNMS looks promissing but still somewhat slow on RPi since it is #PHP+#MySQL app. Can work as a syslog server too.

Things to try:
1. #munin -- probably the lowest hw requirements

Running "modern" stuff like Prometheus+Grafana is out of the scope of course.

UPD: replaced "monit" with "munin" because it is what I originally meant. Thanks @blotza for the suggestion!

@jeroenbosman Dank! I’m afraid I will be missing the Munin conference (just back from Charleston and it would be a bit much to do both). But #Munin is still my favourite so I definitely plan to go back.

It’s sad how "modern" monitoring/metric collection tools fail hard with modern setups. I can do better in 30 seconds with the good old #Munin.

#prometheus #graphana #FreeBSD #ZFS

#munin #monitoring is still great and an active project 👍
And it is super easy to write plugins

@T3Z Ohhh, ein Rabe, warum bin ich darauf nicht gekommen. Bei Odin, ich liebe Raben #Hugin #Munin

After years of hard procrastination and putting off I have finally installed monitoring for my #linux home server.

To make it independent from the server itself, it's running in LXC on the router. #openwrt FTW!

I went with #munin , because it feels much lighter than prometheus + node_exporter + grafana. I also have experience writing custom plugins

If you ever wanted to know what's going on in your talkgroups on your local hotspot, I've you covered. Right now it's in the state of "working for me" and requires some more documentation :) But here is how it looks like. It uses Munin for monitoring - yes, I already older and like #perl

Hugin / Munin

Cyanotype, raven feathers, silk thread.

In Norse mythology, Odins ravens Hugin (thought) and Munin (memory) brought him news from all the worlds.

Initmating at the importance of memory, Odin says;

Huginn and Muninn
fly every day
over the vast earth.
I fear for Hugin
that he won’t return,
though I fear more for Munin

Thought is of the thing itself. Memory, while linked to thought, is something else entirely.

Next week I will be joining the #Munin #conference for the first time. My colleague Tom Mosterd and I will be talking about #OpenAcces #books as a building block for #opensciece.

Such FOMO when it was casually mentioned today in a call that next week in #Tromsø the period with no daylight will have started. #polarnight

Maybe next year I'll finally make it to the #Munin conference in person! (and have an epic train journey to get there)

Here's a few of the #papercuttings I've done over the years (more to come). :) The top two were made from several layers of paper. The bottom two were originally based on ones from a book of fretwork patterns that I heavily modified.
