Synopsis

Why use seaslog

The log journal，which is usually the operate record of the system，software and the application record. Through the analysis of the log，it can facilitate users to understand the operation of the system，software and the application situation. If your application log is rich enough，it can also analyze the previous use’s operation behavior，type ，regional distribution or other more information. The application log also points the multiple levels at the same time, you can easily get the application analysis of health status, timely find problems and quick positioning, and solve the problem, remedy the loss.

The error_log, syslog function which built in PHP is powerful and excellent performance, but due to various defects (error_log have no error level, no fixed format, syslog regardless of module, and mix with system log ), reducing a lot of flexibility , and can't meet the application requirements.

The good news is that there are a number of third-party log class library established to make up for the defects, such as log4php, plog, Analog (of course, there are many applications in the project development of the log class). Of which log4php is the most famous and excellent design, perfect document format , powerful function，which is recommanded.

But log4php did very badly in terms of performance, below chart is SeasLog with log4php ab concurrent performance test (test environment: Ubuntu12.04 standalone, I3 CPU, memory16g，hard disk SATA 7200) : SeasLogVSlog4php

So is there a log of libraries meet the following requirements：

  • Modules, classification
  • Simple configuration(preferably without configuration)
  • Clear log format and easy understanding
  • Simple application and well performance

SeasLog just meet these demands.

What is provided at present

  • In the PHP project, record the log specification and repidly.
  • Configure the default log directory and module
  • Specified log directory and capture current configuration
  • Preliminary analysis of the early warning framework
  • Efficient log buffer and convenient buffer debug
  • Follow the PSR-3 log interface specification
  • Automatically record error information
  • Automatically record abnormal information
  • Support Connect the TCP port, send with RFC5424
  • Support Connect the UDP port, send with RFC5424
  • Support RequestId differentiated requests
  • Support for log template customizations

What is the target

  • Convenient, standarded log records
  • Efficient mass log analysis
  • Configurable, multi-channel log warning

Custom log template

Many friends mentioned the need for custom log templates during their use, so SeasLog began with the 1.7.2 version and has the ability to allow users to customize the template for the log.

At the same time, many preset variables that are preset by SeasLog can be used in the template,please referenceDefault variable table.

Log template overview

  • Default log template is:seaslog.default_template = "%T | %L | %P | %Q | %t | %M",

  • that's mean,default log style is:{dateTime} | {level} | {pid} | {uniqid} | {timeStamp} | {logInfo}

  • If you custom log template, such as:seaslog.default_template = "[%T]:%L %P %Q %t %M"

  • that's will mean,log style was custom as:[{dateTime}]:{level} {pid} {uniqid} {timeStamp} {logInfo}

Default variable table

SeasLogThe following default variables are provided, which can be used directly in the log template and replaced as a corresponding value when the log is eventually generated.

  • %L - Level.
  • %M - Message.
  • %T - DateTime. Such as2017-08-16 19:15:02,affected by seaslog.default_datetime_format.
  • %t - Timestamp. Such as1502882102.862,accurate to milliseconds.
  • %Q - RequestId. To distinguish a single request, such as not invoking the SeasLog::setRequestId($string) function，the unique value generated by the built-in static char *get_uniqid () function is used when the request is initialized.
  • %H - HostName.
  • %P - ProcessId.
  • %D - Domain:Port. Such aswww.cloudwise.com:80; When Cli, Such as cli.
  • %R - Request URI. Such as/app/user/signin; When Cli it's the index script, Such as CliIndex.php.
  • %m - Request Method. Such asGet; When Cli it's the command script, Such as /bin/bash.
  • %I - Client IP; When Cli it's local. Priority value: HTTP_X_REAL_IP > HTTP_X_FORWARDED_FOR > REMOTE_ADDR
  • %F - FileName:LineNo. Such as UserService.php:118.
  • %U - MemoryUsage. byte. Call zend_memory_usage.
  • %u - PeakMemoryUsage. byte. Call zend_memory_peak_usage.
  • %C - Class::Action. Such as UserService::getUserInfo. in procedural programming, it falls back to function name.
  • %B - BasePath. Such as /var/log/www, affected by seaslog.default_basepathandsetBasePath.

Constants and functions

Constant list

SeasLog exposes log level by eight levels.

SEASLOG_DEBUG
  • "DEBUG" - Detailed debug information.Fine-grained information events.
SEASLOG_INFO
  • "INFO" - Interesting events.Emphasizes the running process of the application.
SEASLOG_NOTICE
  • "NOTICE" - Normal but significant events.Information that is more important than the INFO level during execution.
SEASLOG_WARNING
  • "WARNING" - Exceptional occurrences that are not errors.Potentially aberrant information that needs attention and needs to be repaired.
SEASLOG_ERROR
  • "ERROR" - Runtime errors that do not require immediate action but should typically.
SEASLOG_CRITICAL
  • "CRITICAL" - Critical conditions.Need to be repaired immediately, and the program component is unavailable.
SEASLOG_ALERT
  • "ALERT" - Action must be taken immediately.Immediate attention should be given to relevant personnel for emergency repairs.
SEASLOG_EMERGENCY
  • "EMERGENCY" - System is unusable.
var_dump(SEASLOG_DEBUG,SEASLOG_INFO,SEASLOG_NOTICE);
/*
string('DEBUG') debug level
string('INFO')  info level
string('NOTICE') notice level
*/

PHP Re result

SeasLog_PHP_Re_Result

The useage of seaslog logger

Get and set base path

$basePath_1 = SeasLog::getBasePath();

SeasLog::setBasePath('/log/base_test');
$basePath_2 = SeasLog::getBasePath();

var_dump($basePath_1,$basePath_2);

/*
string(19) "/log/seaslog-ciogao"
string(14) "/log/base_test"
*/

Use the Function SeasLog::getBasePath() will get the value of seaslog.default_basepath what configured in php.ini(seaslog.ini).

Use the Function SeasLog::setBasePath() will change the value of function SeasLog::getBasePath().

Get and set logger

$lastLogger_1 = SeasLog::getLastLogger();

SeasLog::setLogger('testModule/app1');
$lastLogger_2 = SeasLog::getLastLogger();

var_dump($lastLogger_1,$lastLogger_2);
/*
string(7) "default"
string(15) "testModule/app1"
*/

Similar to basePath，

Use the Function SeasLog::getLastLogger() will get the value of seaslog.default_logger what configured in php.ini(seaslog.ini).

Use the Function SeasLog::setLogger() will change the value of function SeasLog::getLastLogger().

Fast write log

We have been set the basePath and logger, and then the logger path has be all ready,

logSeasLog will record which level 目录 = basePath / logger / {fileName}.log Log filename, begin with YearMonthDay.It will be {fileName} = 20140218,because today is 02-18-2014.

Would you remember that seaslog.disting_type in php.ini?

Switch Default seaslog.disting_type = 0, If we used SeasLog today, the log file will been finally:

  • LogFile = basePath / logger / 20140218.log

If seaslog.disting_type = 1, the log file would be looks like

  • infoLogFile = basePath / logger / 20140218.INFO.log

  • warnLogFile = basePath / logger / 20140218.WARNING.log

  • erroLogFile = basePath / logger / 20140218.ERROR.log

There are two prototypes of functions for logging：

  • SeasLog::log($level, $messages[, $context, $logger])

  • SeasLog::$level($messages[, $context, $logger])

$level - See the 8 levels listed above

$messages - You can use two types of string or array, and array accepts only one dimensional array.

$context - Only accept one-dimensional array to replace placeholder of log in $messages.

$logger - You can temporarily specify a logger for the current operation without changing the value of the getLastLogger method.

SeasLog::log(SEASLOG_ERROR,'this is a error test by ::log');

SeasLog::debug('this is a {userName} debug',array('{userName}' => 'neeke'));

SeasLog::info('this is a info log');

SeasLog::notice('this is a notice log');

SeasLog::warning('your {website} was down,please {action} it ASAP!',array('{website}' => 'github.com','{action}' => 'rboot'));

SeasLog::error('a error log');

SeasLog::critical('some thing was critical');

SeasLog::alert('yes this is a {messageName}',array('{messageName}' => 'alertMSG'));

SeasLog::emergency('Just now, the house next door was completely burnt out! {note}',array('{note}' => 'it`s a joke'));

$aMessages = array('test log from array abc {website}','test log from array def {action}');
$aContent = array('website' => 'github.com','action' => 'rboot'));
SeasLog::debug($aMessages,$aContent);
/*
These functions can receive `logger` cased by the third param all the time.
Tips:  `last_logger == ‘default’` will be used same to:
SeasLog::setLogger('test/new/path');
SeasLog::error('test error 3');
The `logger` cased by the third param would be used right this right now, like a temp logger, when the function SeasLog::setLogger() called in pre content.
*/

Log style affected byseaslog.default_template. As the default, seaslog.default_template = "%T | %L | %P | %Q | %t | %M" that's mean,as the default,log record style is： {dateTime} | {level} | {pid} | {uniqid} | {timeStamp} | {logInfo}. About custom log template,and how to use default variable table,see Custom log template

Data format when sent by TCP or UDP

SeasLog will send log to tcp://remote_host:remote_port or udp://remote_host:remote_port server, when seaslog.appender configured to 2 (TCP) or 3 (UDP).

When SeasLog send log to TCP/UDP，style follow RFC5424 log style is formatted by SeasLog with send header:<PRI>1 {timeStampWithRFC3339} {HostName} {loggerName}[{pid}]: {logInfo} The {logInfo} affected by seaslog.default_template.

The log style finally formatted such as:

Manually release stream flow from logger

`SeasLog' caches the stream handle opened by the log logger to save the overhead of creating a stream. The handle will be automatically released at the end of the request. If in CLI mode, the process will also automatically release when it exits. Or you can use the following functions to manually release(manually release function needs to update SeasLog 1.8.6 or updated version).

Manually release all of the logger stream handle：

SeasLog::closeLoggerStream();

or

SeasLog::closeLoggerStream(SEASLOG_CLOSE_LOGGER_STREAM_MOD_ALL);

Manually release the specified logger stream handle：

SeasLog::closeLoggerStream(SEASLOG_CLOSE_LOGGER_STREAM_MOD_ASSIGN, 'logger_name');

The useage of SeasLog Analyzer

Fast count some type of log count value

SeasLog get count value of grep -wc use system pipe and return to PHP (array or int).

$countResult_1 = SeasLog::analyzerCount();
