Overview

Hey supports two output formats: summary and CSV

The summary output presents a number of statistics about the requests in a human-readable format, including: - general statistics: requests/second, total runtime, and average, fastest, and slowest requests. - a response time histogram. - a percentile latency distribution. - statistics (average, fastest, slowest) on the stages of the requests.

The comma-separated CSV format is proceeded by a header, and consists of the following columns: 1. response-time: Total time taken for request (in seconds) 2. DNS+dialup: Time taken to establish the TCP connection (in seconds) 3. DNS: Time taken to do the DNS lookup (in seconds) 4. Request-write: Time taken to write full request (in seconds) 5. Response-delay: Time taken to first byte received (in seconds) 6. Response-read: Time taken to read full response (in seconds) 7. status-code: HTTP status code of the response (e.g. 200) 8. offset: The time since the start of the benchmark when the request was started. (in seconds)

Package requester provides commands to run load tests and display results.
