A port of log4js to node.js
Sends logging events to Loggly, optionally adding tags. This appender uses node-loggly, and you will need to include that in your dependencies if you want to use this appender. Consult the docs for node-loggly, or loggly itself, if you want more information on the configuration options below.
type - logglytoken - string - your really long input tokensubdomain - string - your subdomaintags - Array<string> (optional) - tags to include in every log messageThis appender will scan the msg from the logging event, and pull out any argument of the
shape { tags: [] } so that it’s possible to add additional tags in a normal logging call. See the example below.
log4js.configure({
  appenders: {
    loggly: {
      type: 'loggly',
      token: 'somethinglong',
      subdomain: 'your.subdomain',
      tags: [ 'tag1' ]
    }
  },
  categories: {
    default: { appenders: ['loggly'], level: 'info' }
  }
});
const logger = log4js.getLogger();
logger.info({ tags: ['my-tag-1', 'my-tag-2'] }, 'Some message');
This will result in a log message being sent to loggly with the tags tag1, my-tag-1, my-tag-2.
