logFaces Appender (HTTP) for log4js-node

The logFaces appenders send JSON formatted log events to logFaces receivers. This appender uses HTTP to send the events (there is another logFaces appender that uses UDP).

npm install log4js @log4js-node/logfaces-http

Configuration

• type - @log4js-node/logfaces-http
• url - string - logFaces receiver servlet URL
• application - string (optional, defaults to empty string) - used to identify your application's logs
• timeout - integer (optional, defaults to 5000ms) - the timeout for the HTTP request.

This appender will also pick up Logger context values from the events, and add them as p_ values in the logFaces event. See the example below for more details.

Example (default config)

log4js.configure({
  appenders: {
    logfaces: { type: 'logFaces-HTTP', url: 'http://lfs-server/logs' }
  },
  categories: {
    default: { appenders: [ 'logfaces' ], level: 'info' }
  }
});

const logger = log4js.getLogger();
logger.addContext('requestId', '123');
logger.info('some interesting log message');
logger.error('something has gone wrong');

This example will result in two log events being sent to lfs-server. Both events will have a p_requestId property with a value of 123.
