> The metrics2 system was implemented to deal with persistent sources.
> {{ContainerMetrics}} is an ephemeral source, and so it causes problems.
> Specifically, the {{ContainerMetrics}} only reports metrics once after the
> container has been stopped. This behavior is a problem because the metrics2
> system can ask sources for reports that will be quietly dropped by the sinks
> that care. (It's a metrics2 feature, not a bug.) If that final report is
> silently dropped, it's lost, because the {{ContainerMetrics}} won't report
> anything else ever anymore.
