straceout-utils

Build Status

A set of tools for working with strace out.

Installation

PHAR

From Source

  • Clone the repository from GitHub
  • Run composer install

TIP: If installing from source, execution entry point is bin/straceout-utils

Features

MySQL Query Results

strace out will include the packets received from MySQL in Client / Server Protocol format. This is not a format that can be read by humans. straceout-utils will process these packets and transform them into a format that is digestable for humans.

Notes

  • You must use the strace -x flag so that the packets are in hex format
  • When capturing the strace use the -s flag to ensure that strings are not truncated. It is not possible to reconstruct the query response if they are.

Example

Obtain the strace

In this example we capture an strace of execution of the script test.php.

$ strace -s 65535 -x -o strace-out.txt php test.php

Process the strace output

straceout-utils writes output to stdout. In this example we sent that to a new text file, named straceout-utils-out

$ straceout-utils process strace-out.txt > straceout-utils-out.txt
