Description
[FATAL] There is nothing to do here, since there are no nodes with any plugins. Please refer to http://munin-monitoring.org/wiki/FAQ_no_graphs at /usr/lib/munin/munin-html line 38.
I couldn't find much hints, except https://debianforum.de/forum/viewtopic.php?t=131809 where the OP says that setting host_name in munin-node.conf helped.
I did that now and set host_name openqa.opensuse.org in /etc/munin/munin-node.conf.
tinita applied changes that could improve the situation. Right now no problem resides. We will see if that alerts us again.
Happened again today Date: Thu, 6 Feb 2025 09:55:22 +0000 (UTC). No idea why.
I think we can just ignore it, but it would be good to have an automatic way to ignore this and not receive an email.

Hmm. I tried something else now.
Maybe I hadn't restarted the service when I did the config change last time. So I set host_name openqa.opensuse.org again and then restarted munin-node.service.
Then:
telnet localhost 4949
Trying ::1...
Connected to localhost.
Escape character is '^]'.
# munin node at openqa.opensuse.org
quit
Connection closed by foreign host.
if I understand the FAQ correctly, this should now be enough to let munin believe the hostname is openqa.opensuse.org, which should be the displayed titles in the graphs.
