Some metrics are being emitted using Twill run id

Some metrics like system.resources.used.containers, system.resources.used.memory and system.resources.used.vcores are emitted using Twill run id or Twill internal id for a container.

Twill run ids are not exposed through CDAP and does not make sense to our users. We should instead use CDAP run id and/or instance id for such metrics.

For instance -

In the above query -

• 78341031-3bdc-11e5-8bd2-42010af04085 is CDAP run id

• 88725e7e-84e5-423b-91a6-9bff35ae2fec is Twill run id

• c4c3e063-44d4-402c-aff7-01d8491dee36-0, 872bbf5c-355f-4293-b2f4-954b1f867b76-0 and e7e25178-4c8c-434e-b16c-6b9c1559b0c5-0 are Twill internal container run ids.
