Why use SeasLog

Log logs are generally the running records of systems, software, and applications. Log analysis helps you understand the running status of systems, software, and applications. if your application logs are rich enough, you can also analyze the user's operation behavior, type preferences, region distribution, or other information in the past. if the log of an application is divided into multiple levels, you can easily analyze the health status of the application, identify problems in time, quickly locate and solve problems, and remedy the losses.

The built-in error_log and syslog functions of php are powerful and have excellent performance. However, due to various defects (error_log has no error level and no fixed format, syslog is not divided into modules and mixed with system logs ), flexibility is much lower and cannot meet application requirements.

The good news is that many third-party log class libraries make up for the above defects, such as log4php, plog, and Analog (of course there are also many log classes developed by applications in the project ). Among them, log4php is the most famous, well-designed, well-formatted, well-documented, and powerful. Recommended.

However, log4php performs very poorly in terms of performance. it is the AB concurrent performance test of SeasLog and log4php (test environment: Ubuntu12.04 single-host, CPU I3, 16 GB memory, hard disk SATA 7200 ):

Is there a log class library that meets the following requirements:

• Modules and levels

• Easy configuration (preferably not required)

• Log Format is clear and easy to read

• Simple application and excellent performance

SeasLog is generated based on this requirement.

What are currently provided

• Easily and standardizes log recording in PHP projects

• Configurable default log directories and modules

• Specify the log directory and obtain the current configuration

• Preliminary analysis and warning framework

• Efficient log buffer and convenient buffer debug

• Compliance with PSR-3 log interface specifications

• Automatically record error information
• Automatically record exception information

What is the goal?

• Convenient and standard log records

• Efficient massive log analysis

• Configurable and multi-channel log warning

Install, compile, and install SeasLog

$ /path/to/phpize$ ./configure --with-php-config=/path/to/php-config$ make && make install

Install SeasLog in PECL

$ pecl install seaslog

Seaslog. ini configuration

; Configuration for php SeasLog moduleextension = seaslog. soseaslog. default_basepath =/log/seaslog-test; the default log root directory is seaslog. default_logger = default; default logger directory seaslog. disting_type = 1; whether to split files by type; 1 is 0 No (default) seaslog. disting_by_hour & nnbsp; = 1; whether to divide a file every hour; 1: 0; No (default) seaslog. use_buffer = 1; whether to enable buffer 1 is 0 No (default) seaslog. buffer_size = 100; buffer quantity defaults to 0 (no buffer_size is used) seaslog. level = 0; default log level 0 (all logs) seaslog. trace_error = 1; automatic record error default value: 1 (enabled) seaslog. trace_exception = 0; automatic recording of exception information defaults to 0 (off) seaslog. default_datetime_format = "% Y: % m: % d % H: % M: % S"; default date format configuration "% Y: % m: % d % H: % M: % S"

Seaslog. disting_type = 1. enable file separation by type, that is, the log file distinguishes info \ warn \ erro.

Seaslog. disting_by_hour = 1. enable file division every hour.

Seaslog. use_buffer = 1 enable buffer. Disabled by default. When this option is enabled, logs are pre-stored in memory, and files are written at the end of the request (or when an exception exits.
