As a note, these metric collectors do work for custom HardwareManagers as
well, however, you may want to metric the portions of a method that determine
compatability separate from portions of a method that actually do work, in
well. However, you may want to metric the portions of a method that determine
compatibility separate from portions of a method that actually do work, in
order to assure the metrics are relevant and useful on all hardware.
Explicitly sending metrics
==========================
A feature that may be particularly helpful for deployers writing custom
HardwareManagers is the ability to explicitly send metrics. As an example,
HardwareManagers is the ability to explicitly send metrics. For instance,
you could add a cleaning step which would retrieve metrics about a device and
ship them using the provided metrics library. For example::
