Could you please describe your use case? What plugin is it? Did you consider using the dataType="trait" attribute? This is my own plugin.
My particular use case is this metric:
<metric property="hbaseLastProcessDate"
dataType="measurement"
description="HBase last processing date"
units="epoch_milliseconds"/>
I have a component that loads data periodically (say, every minute),
but regularly into HBase. This metric tracks the last time data was
completely loaded. I get this from parsing an actual string from a
file, e.g.:
'201209122216'
As a trait, the value would change very frequently. RHQ would store a
new value for the trait, as a String, every time the metric was
polled.
But as a measurement, RHQ would instead store a 'double'. Storing as a
metric allows for a few different things as well:
1. Change formatting depending on the browser & user local time zone.
2. See trending. Ideally, the 'last time' would increase at a steady rate.
3. Alarm if the value does not change.
4. Alarm if the value is, say, 1 hour ago and the threshold is 10 minutes.
Alternatively, the metric could be defined as a relative time value:
<metric property="hbaseLastProcessSecondsAgo"
dataType="measurement"
description="For HBase, how many seconds ago was the
data processed"
units="seconds"/>
I don't really mind switching to relative time, but it seems
reasonable to support this in the UI.

It appears setting the units for a measurement to 'epoch_milliseconds' doesn't format the value as an actual date/time when the value is displayed. Instead is displayed a large number. <metric property="lastProcessDate" dataType="measurement" description="last processing date" units="epoch_seconds" displayType="summary" category="performance" /> I'm guessing there is some code missing in here to do the format: enterprise/gui/coregui/src/main/java/org/rhq/enterprise/gui/coregui/client/util/MeasurementConverterClient.java I do see some code in: enterprise/gui/portal-war/src/main/java/org/rhq/enterprise/gui/legacy/util/MonitorUtils.java but it seems like this is no longer used?
