Missing organization/space/app name in application task logs coming from Aggregate Syslog Drain

Products

• VMware Tanzu Application Service for VMs

Issue/Introduction

Application logs will be streamed to syslog drain endpoints which are configured in TAS Settings -> System Logging -> Aggregate syslog drain destinations. The streamed logs will be tagged with metadata including organization.space.app names. For example, the following logs from application app-usage-worker (in organization system, space system) are tagged with system.system.app-usage-worker.

However logs from application task are not tagged with organization.space.app names.

Environment

Product Version: 2.13

Resolution

Engineering team has determined this expected behavior at the moment, however they are working on a change for this feature. It is a larger change that will include changes to Diego and Cloud Controller, so it will take a bit longer to release a fix.
