Hi Florian, thx for your response.

Unfortunately I don't have a zfs_arch folder into my rrd folder.....(on the collectd server).

this error message has nothing to do with the "zfs_arc" plugin, but with the "interface" plugin. You can resolve it by ignoring the interface called "mac", that for some reasons is reported multiple times under certain versions of Solaris. You can do this using the "Interface" and "IgnoreSelected" options of the "interface" plugin, which are documented in the collectd.conf(5) manual page.

Do you have a directory named "zfs_arc" somewhere beneath the RRD data directory? You can use find(1) to look for it, for example:

  $ find /var/lib/collectd/rrd -name zfs_arc -type d
