Description

To improve the observability is a key requirement to achieve better correctness and performance with Ozone.

This jira collects some of the tasks which can provide better visibility to the ozone internals.

We have two main tools:

• Distributed tracing (opentracing) can help to detected performance battlenecks
• Ozone insight tool (a simple cli frontend for Hadoop metrics and log4j logging) can help to get better understanding about the current state/behavior of specific components.

Both of them can be improved to make it more powerful.

Sub-Tasks

• Use annotations to define description/filter/required filters of an InsightPoint: Open
• Support Ozone insight tool in secure cluster: Open
