Seems like your image suffers from alpinelinux/docker-alpine#135 (comment)

I just found your container..

Do you think it is possible to monitor the dns server unbound?

https://www.nlnetlabs.nl/documentation/unbound/howto-statistics/

This looks to depend on a local binary..

Have you ever used this for unbound, or only snmp hosts?

Will test and see what I can see..

Regardless, thank you in advance.

This may be a simpler / lightweight alternative to observium.. (which does not have rrdcache or fcgi..)

The container has a pretty old version of Munin, can it be updated to the last release?

Hi,

I am trying the container with a docker-compose file as below.
When I put the SNMP_NODES in comment, the container starts without any problems.
However when I would try to use the SNMP_nodes, the container seems to stop somewhere.
Maybe I made a mistake somewhere, but I don't see it.
Can somebody see what the mistake is ?

Kind regards

Tore

Using Dive you can see that some layers could be avoided

And that /var/cache/fontconfig could probably be cleaned up

Hello,
Let me thank you for the project.

I was wondering if/when will be implemented logrotate feature?

Because after some time (lots of time), I and other users will be in this situation:

/var/log/munin# ls -lh
total 23G
-rw-rw-r--+ 1 nginx munin 2.5M Oct 23 2022 munin-cgi-graph.log
-rw-rw-r--+ 1 nginx munin 9.1K Oct 23 22:07 munin-cgi-html.log
-rw-rw-r--+ 1 nginx munin 19M Nov 7 20:15 munin-graph.log
-rw-rw-r--+ 1 nginx munin 124M Nov 7 20:15 munin-html.log

-rw-rw-r--+ 1 nginx munin 23G Nov 7 20:15 munin-update.log

Kind regards.

Hi! It would be nice to have IPv6 address support here. Currently if I use an IPv6 address as IP, the parsing and config generation breaks because the address have ":" in them.

The container installs both the server as the client (munin-node). And automaticly adds this node to the config-file.

I would really like an option to disable this munin-node, and keep only the server (to watch remote instances). Since it doesn't make much sense to run this node inside a container anyway, since a lot of metrics are not available (like temperature sensors, etc).

Having some ENVs to make symlinks from /usr/lib/munin/plugins/ to /etc/munin/plugins/
