pinus-logger

pinus-logger is a log4js wrapper for pinus which provides some useful features.

Installation

npm install pinus-logger

Features

log prefix

besides category, you can output prefix as you like in your log
prefix can be filename, serverId, serverType, host etc
to use this feature, you just pass prefix params to getLogger function

var logger = require('pinus-logger').getLogger(category, prefix1, prefix2, ...);

log output msg will output with prefix ahead

get line number in debug

when in debug environment, you may want to get the line number of the log
to use this feature, add this code

process.env.LOGGER_LINE = true;

in pinus, you just configure the log4js file and set lineDebug for true

{
  "appenders": [
  ],

  "levels": {
  }, 

  "replaceConsole": true,

  "lineDebug": true
}

log raw messages

in raw message mode, your log message will be simply your messages, no prefix and color format strings
to use this feature, add this code

process.env.RAW_MESSAGE = true;

in pinus, you just configure the log4js file and set rawMessage for true

{
  "appenders": [
  ],

  "levels": {
  }, 

  "replaceConsole": true,

  "rawMessage": true
}

dynamic configure logger level

in pinus logger configuration file log4js.json, you can add reloadSecs option. The reloadSecs means reload logger configuration file every given time. For example

{
	"reloadSecs": 30
}

the above configuration means reload the configuration file every 30 seconds. You can dynamic change the logger level, but it does not support dynamiclly changing configuration of appenders.

Example

log.js

var logger = require('pinus-logger').getLogger('log', __filename, process.pid);

process.env.LOGGER_LINE = true;
logger.info('test1');
logger.warn('test2');
logger.error('test3');
