You can use this plugin to manually log data or to capture logging on WordPress actions. You can capture load time, memory, backrace, data dumps, urls, and server IPs.<\/p>\n\n
This is designed to either be managed using wp-config.php and logging OR using the admin and debugbar plugin ( http:\/\/wordpress.org\/extend\/plugins\/debug-bar\/ ). Most of the following documentation applies equally to the settings panel or the wp-config.php vars. Either one works fine. The only exception is the DEBUG_LOG configuration which is only supported as a wp-config var.<\/p>\n\n
Firstly, you can manually log things using the following function:<\/p>\n\n
do_action( 'log', $message, $group, $data );\n<\/code><\/pre>\n\nThe $group allows you to selectively output logging based on groups of log messages. The $message is the string you want to see in the log. $data is an optional parameter for the data that you want to display in the log (objects, arrays, or any other sort of data really).<\/p>\n\n
To render messages to the log, you must configure wp-config.php as follows:<\/p>\n\n
Run debug on only these groups. Use 'ALL' to debug everything. The group 'ACTIONS' is reserved for WordPress actions.<\/p>\n\n
define( 'DEBUG_GROUPS', 'ACTIONS,default,myspecialgroup' );\n<\/code><\/pre>\n\nDisplay these outputs in the log for each log message.<\/p>\n\n
define( 'DEBUG_PARAMS', 'time,timedelta,memory,memorydelta,data,backtrace,url,server' );\n<\/code><\/pre>\n\nWordPress actions that you wish to log.<\/p>\n\n
define( 'DEBUG_ACTIONS', 'wp_head,switch_theme,wp_footer' );\n<\/code><\/pre>\n\nOptional restriction by URL (useful on MU installs).<\/p>\n\n
define( 'DEBUG_URLS', 'myurl.com' );\n<\/code><\/pre>\n\nMinimum time in milliseconds required to register a log entry as being slow. Default 0 for no minumum.<\/p>\n\n
define( 'DEBUG_MIN_TIME', 500 );\n<\/code><\/pre>\n\nMinimum memory in killobytes required to register a log entry as being heavy. Default 0 for no minumum.<\/p>\n\n
define( 'DEBUG_MIN_MEM', 1024 );\n<\/code><\/pre>\n\nPath to log file or set to TRUE to use php error log. Default FALSE for no logging.<\/p>\n\n
define( 'DEBUG_LOG', '\/path\/to\/writable\/log\/file' );\n<\/code><\/pre>\n\nor<\/p>\n\n
define( 'DEBUG_LOG', TRUE );\n<\/code><\/pre>\n\nTodo<\/h4>\n\n\n- Add variable for sample rate so that this could run randomly on production installs<\/li>\n
