Node.js

Papertrail can accept logs from any Node.js app using a regular text log file or the libraries winston or bunyan.

If the Node.js app is running on Heroku, try the Heroku setup instead.

Send log file with remote_syslog2

Have Node log to a file, then transmit the log file to Papertrail using remote_syslog2.

To make Node log to a file, either redirect its output or use the fs module. For example, to redirect stdout to myapp.log, start the daemon with:

$ nohup node myapp.js > myapp.log &

Send events from Node.js

To asynchronously transmit events from Node.js, use the winston-syslog transport:

const os = require('os');
const winston = require('winston');
require('winston-syslog');

const papertrail = new winston.transports.Syslog({
  host: 'logsN.papertrailapp.com',
  port: XXXXX,
  protocol: 'tls4',
  localhost: os.hostname(),
  eol: '\n',
});

const logger = winston.createLogger({
  format: winston.format.simple(),
  levels: winston.config.syslog.levels,
  transports: [papertrail],
});

logger.info('hello papertrail');

See the README for more information about the winston-syslog transport. To log unhandled exceptions, see the winston documentation.

If syslog isn’t available, Winston’s native HTTP transport can be used with Papertrail’s Token-based destination. This sends messages using a non-customizable JSON format.

const winston = require('winston');

const papertrail = new winston.transports.Http({
  host: 'logs.collector.solarwinds.com',
  path: '/v1/log',
  auth: { username: new String(''), password: 'TOKEN' },
  ssl: true,
});

const logger = winston.createLogger({
  transports: [papertrail],
});

logger.info('hello papertrail');

node-bunyan users can use the node-bunyan-syslog stream.

node-posix library for sending to local system syslog daemon, which can then relay to Papertrail using standard syslog instructions.
rconsole for logging Node console to local syslog.
