Debian provides a default file /etc/munin/plugin-conf.d/munin-node which
already contains a [df] section. If you are adding a new file you may end
with dupicate sections. Be carefull that no other [df] section exists in
any other file in /etc/munin/plugin-conf.d/ . From memory, only the last
section is used; files override each other; they are read in alpha order.

env.exclude_re is not taking arguments as keywords, but as regexp. Your
line seems fine to me.


The regexp must match the output of df. I know tons of case where mount
and df show different devnames.

Depends if your distro had put a df section in the default conf file.

But since p comes after d, your hand made file was probably ignored. I
mean, the folder can contain many files, but when two sections with the
same name exist in several files, only the one from the last file is used.

But if you rename your file zdf, or put your section at the end of
plugings.conf then your will override the default settings.

After editing conf, you need to reload the node, and wait for 2 updates
(usually 10mn).

or, phrase it the Windows way:
"did you try to reboot to apply the change ?".
