Quality Assessment: Content is clearly written and understandable

Criteria: Clarity, directness, avoidance of ambiguity.

Task: Assess clarity.

Output Format:

• Clear Sections: The "Build controller metrics" table is very clear, providing specific labels for each metric.
• Ambiguity: In ob-histogram-metrics.adoc, the default values for PROMETHEUS_BR_EST_DUR_BUCKETS are listed as 0,1,2.... It might be helpful to clarify if these units are seconds, milliseconds, etc., although the metric name ..._seconds implies it. Explicitly stating "Values are in seconds" in the description would ensure clarity.
