@Jeremy_Lecour There are probably more incorrect paths, as the path was probably not set correctly during the setup. See also here: https://github.com/jlecour/rrdbeat/blob/master/beater/rrdbeat.go#L12 Best is to search for it and replace it. Or in case you haven't made changes to the repo yet, you could generate a new version and make sure the path is correct.
Let me know in case you hit some more issues so we can fix it.
