Documentation

Overview

Package template documents the way user-defined output templates are ment to be used.

User-defined templates use Go's text/template package, so you might want to check its documentation first. There are a bunch of helper methods available inside a template besides those described in aforementioned documentation, namely:

  • WithLatencies() Tells whether --latencies flag were activated.
  • FormatBinary(numberOfBytes float64) string Converts bytes to kilo-, mega-, giga-, etc.- bytes, and appends appropriate suffix "KB", "MB", "GB", etc.
  • FormatTimeUs(us float64) string Converts microseconds to milliseconds, seconds, minutes or hours and appends appropriate suffix.
  • FormatTimeUsUint64(us uint64) string Same as above, but for uint64, since type conversions are not available in templates.
  • FloatsToArray(ps ...float64) []float64 Converts a bunch of floats into array, since, again, type conversions are not available in templates.
  • Multiply(num, coeff float64) float64 Arithmetics are not available inside of templates either.
  • StringToBytes(s string) []byte Convenience function to convert string to []byte.
  • UUIDV1() (UUID, error) Generates UUID Version 1, based on timestamp and MAC address (RFC 4122)
  • UUIDV2(domain byte) (UUID, error) Generates UUID Version 2, based on timestamp, MAC address and POSIX UID/GID (DCE 1.1)
  • UUIDV3(ns UUID, name string) UUID Generates UUID Version 3, based on MD5 hashing (RFC 4122)
  • UUIDV4() (UUID, error) Generates UUID Version 4, based on random numbers (RFC 4122)
  • UUIDV5(ns UUID, name string) UUID Generates UUID Version 5, based on SHA-1 hashing (RFC 4122)

The structure that gets passed to the template is documented in the package github.com/codesenberg/bombardier/internal. The structure of interest is TestInfo. It basically consists of Spec and Result fields, the former contains various information about the test (number of connections, URL, HTTP method, headers, body, rate, etc.) performed, while the latter contains results obtained during the execution of this test (bytes read/written, time taken, RPS, etc.).
