the loggregator team would like to remove the /containermetrics endpoint on the loggregator_trafficcontroller (see here: https://github.com/cloudfoundry/loggregator-release/blob/master/docs/trafficcontroller.md#endpoints). This endpoint originally was introduced as an endpoint for the Cloud Controller to fetch metrics about the running container.
As of cf-deployment v7.2 (https://github.com/cloudfoundry/cf-deployment/releases/tag/v7.2.0), Cloud Controller now reaches out to log-cache to fetch the container metrics. 

Therefore, we would like to remove this endpoint to keep our API and code base lean and clean. If there are consumers of this endpoint besides the Cloud Controller, please let us know. 

Thanks,

Johannes
