All logs – From Kubernetes (providing logs from services and pods), and from Usage Engine (providing logs from Execution Context, Platform, and workflows) – are easy to send to a Unified Logging Layer like Fluentd. The file format is JSON (log4j & RFC5424 standards). If no third party is used, the files can be read from a shared file system or sent to Kubernetes storage.  

The visualization and management of messages can be done with a product like Elasticsearch.
