    logzilla

    NPM

    The simple winston based logging adapter using in devebot.

    Usage

    Installs logzilla module:

    $ npm install --save logzilla

    Creates a logzilla object and initializes it:

    var LoggerFactory = require('logzilla');
    var factory = new LoggerFactory({
      logger: {
        transports: [{
          type: 'console',
          level: 'trace'
        }, {
          type: 'dailyRotateFile',
          level: 'trace',
          json: false,
          datePattern: '.yyyy-MM-dd',
          filename: 'dailyfile.log'
        }, {
          type: 'logstash',
          level: 'trace',
          silent: true,
          host: '127.0.0.1',
          port: 28777
        }]
      }
    });
    var logger = factory.getLogger();

    Uses the helper methods to log messages:

    logger.error(' - this is an error: %s', err);
    logger.warn(' - alert: this record should be index again.');
    logger.trace(' - marks the startpoint of process ...');
    logger.info(' - object detail: %s', JSON.stringify(doc));
    logger.debug(' - display data and process in details');

    Change logger's level

    To change logger level at runtime, you should use the setLevel() method:

    // ... code that uses old loglevel
     
    // set 'error' level to all transports
    logger.setLevel('error');
     
    // set 'trace' level to only 'console' transport
    logger.setLevel('trace', 'console'); 
     
    // set 'debug' level to both 'console' and 'logstash' transports
    logger.setLevel('debug', ['console', 'logstash']);
     
    // ... code that uses new loglevel

    You can reset all logger transport levels to default levels:

    logger.resetDefaultLevels();

    Enable/disable transports

    To disable the transports at runtime, use the follow method call:

    // disable the logstash transport
    logger.deactivate('logstash');
    //logger.activate('logstash', false);
     
    // or the list of transports
    logger.deactivate(['dailyRotateFile', 'logstash']);
    //logger.activate(['dailyRotateFile', 'logstash'], false);

    To enable the tranports at runtime, use the true value in activate() method:

    // enable the logstash transport
    logger.activate('logstash');
     
    // or the list of transports
    logger.activate(['dailyRotateFile', 'logstash']);
