some of the graphs generated don't make much sense so I'd like to change the graphs upper and lower limits for certain plugins.
I have found a few links as http://munin-monitoring.org/wiki/graph_args
but I still haven't figured out how to change i.e. only the upper limit for one plugin, i.e. apache_accesses ?
I tried editing the file /etc/munin/plugin-conf.d/munin-node adding something like this:
graph_args --upper-limit 50
but that didn't seem to work...
