object will automatically add a `metric` tag to each data point. This correlates to the
-perfdata label. Fields (value, warn, crit, min, max) are created from data if available
+perfdata label. Fields (value, warn, crit, min, max, unit) are created from data if available

resolved, it will be dropped and not sent to the target host.
