What's New
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.
