---------------------------------------
ffosilva commented on pull request #7987: KAFKA-9456: Add support for printing
all the latencies
URL: https://github.com/apache/kafka/pull/7987
There's a new optional argument called 'latencies_csv'. The allowed values
is "0" (disabled) or "1" (enabled).
If enabled, after execution, it will print to stdout all the latencies
stored instead of a brief report. I've also changed the partial latency prints
during the test to 'stderr'.

> EndToEndLatency: Add support for printing all latencies
> -------------------------------------------------------
>
> Key: KAFKA-9456
> URL: https://issues.apache.org/jira/browse/KAFKA-9456
> Project: Kafka
> Issue Type: New Feature
> Components: tools
> Reporter: Fábio Silva
> Assignee: Fábio Silva
> Priority: Major
> Labels: pull-request-available
>
> The EndToEndLatency tool already stores all the latencies but it only prints
> a brief report containing the mean latency and some percentiles. The main
> idea of this feature is to have a flag to enable printing all the latencies
> instead of a report.
> Printing all the latencies is important if the goal of testing is to plot a
> chart (such a boxplot) for example, extract confidence intervals, wherever.
