I think these would be handy, especially when troubleshooting Agent JVM crashes as I have been recently.
We already have a "uptime" metric. It is not appropriate for a trait, it changes everytime it is collected. It is off by default, you have to enable it (see: defaultOn="false"). <metric property="Uptime" displayName="Up Time" description="Total number of seconds since the agent was started" defaultOn="false" units="seconds" category="availability" measurementType="dynamic" /> <!-- changed to dynamic to prevent generation of per Minute metric. -->
changing subject to "add start time trait" - we already have uptime metric.
Move features/improvements to 1.4
