After some munin update i'm not able to run the docker_cpu plugin anymore. Maybe it could be happened a year ago or more, i didn't check the munin page in long time

I get this in the logs

Error output from docker_cpu:
syntax error at /etc/munin/plugins/docker_cpu line 103, near "print"
Execution of /etc/munin/plugins/docker_cpu aborted due to compilation errors.

Unfortunately, I have no knowledge of Perl to understand what's going on

hi, running this plugin on a server with 16 cores, i see avg usage of each container around 3%, but because the scale of the Y is set to 24000%, it's invisible. There's any way i can lower the scale?

Thanks

Raspberry Pi (Raspbian)

Using a Raspberry Pi with Raspbian it could happen no memory is reported and thus docker_memory fails with an error in line 308 when trying to access values. In such case the Docker API does not report it. Making the following changes, fixes the problem:

Open the file /boot/cmdline.txt
Add the following to the end of the existing line cgroup_enable=cpuset cgroup_memory=1 cgroup_enable=memory
Reboot your Raspberry Pi
NOTE: Add the line to the existing line, do not replace it

docker_cpu works, docker_memory gives no data at all (config works, but even that doesn not contain any containers listed). no error either.

environment is debian 8.10
feel free to ask if there is any help i can provide finding the error
