[Nagiosplug-devel] check_disk option for Centreon

[DOGUET Emmanuel]

	Hello,

With centreon the format "label=value[uom]" don't produce graph with real unit.  I'm prefere force "bytes" unit for example and Centreon convert display in MB, GB.

For compatibility it can be juste an option "--force-bytes-perfdata"


	Best regards.

This is definitely something that will have to change; unfortunately we
can't just change it between releases and break everyone's graphs. This
will have to wait until a major release, end even then it would be best
to provide a backward-compatibility option.

For that reason I think it will be best to wait for the new thresholds
format, as the new format will allow adding such options and should be
the main feature of the next major release.

There is an RFC for the new thresholds, although we still have to
publish additional design notes that were discussed during the last OSMC
conference. Anyone willing to help coding this feature is welcome; the
current RFC is available here:
