By default this only write a summary line every few milliseconds, but with {{--detailedResponse}} option, it writes every single response. > Option to collect latencies for individual requests > --------------------------------------------------- > > Key: HBASE-13124 > URL: https://issues.apache.org/jira/browse/HBASE-13124 > Project: HBase > Issue Type: Improvement > Components: Performance, test > Affects Versions: 0.98.6 > Reporter: Hari Krishna Dara > Attachments: HBASE-13124-1.patch > > > Currently, the only option in {{PerformanceEvaluation}} is to print latency percentile summary at the end, and it is also not suitable if we are testing for a long duration (as all the timings are collected in memory). There should be an option to dump the latencies with a timestamp as CSV to a file so that this allows a detailed analysis on the generated data, such as: > - Percentile calculation at the desired precision on the latencies > - Latencies over time > - Histograms -- This message was sent by Atlassian JIRA (v6.3.4#6332)
