Prometheus::Summary

A Summary captures individual observations from an event or sample stream and summarizes them with count and sum.

Use a Summary for metrics where you need the count and sum, such as:

• Request latencies
• Request sizes
• Response sizes

Example:

summary = Summary.new("request_size", "Request size in bytes")
summary.observe(1024)

Summaries track:

• Count of all observed values
• Sum of all observed values
