Remove "feature_flag" from known_events
Problem
When defining a RedisHLL metric there are some keys that need to be defined in the known_events
file, feature_flag
is one of them. To make the creation of metrics easier and have less differences between different types of metric we want to get rid of known_events
in favor of defining all properties of an event inside the metrics *.yml file.
Proposal
Remove the feature_flag
functionality from known events.
Reasoning:
- The
feature_flag
functionality was used in the past but is not used a lot right now - There is a fallback to just use normal feature flag functionality even if that is not as elegant
- There is no clear replacement for the functionality yet in the metric definition files and building one would need more thoughts put into it
Implementation
Remove current usage of `feature_flag` setting ... (#388784 - closed) should make sure that this feature is no longer actively used and related code can just be removed.
