Bitters

A multi transport logging package for the hive platform. The logger can support any logger the implements the winston logging interface. Out of the box the logging package supports file transports for a log file that will get rotated every day, stdout which simply dumps all logs to the host computers stdout, and syslog which attempts to send logs to a running syslog server over udp.

Configuration

Logging options are set using the hive conf package so you can set you logging options as you would everything else. You use the --logger or -l the flag can be passed mutliple times to specify multiple transports. There is always an exception transport called stderr in the config that will always write to stdout For example, if you wanted to log to syslog, but also get feedback from stdout:

node server.js --logger=stdout --logger=syslog

trasport specific configuration can be specified using the log:<TRANSPORT> prefix. For example you can disable the json formatting by passing the prettyPrint option a falsy value.

node server --logger=stdout --log:stdout:prettyPrint=0
node server --log:stderr:prettyPrint=1

Available Transports

Name	Description
stdout	prints output to the current stdout
syslog	sends logs to a syslog server over UDP
file	Writes logs to a file that is rotated daily
papertrail	Sends logs to a configured papertrail server

Logging

The logging package exports a fully configured winston interface that supports syslog logging levels. Each level is method on the interface that logs with the logging level, tag and logging level

var logger = require('bitters')
logger.http('hello world')
logger.debug('hello world')
logger.info('hello world')
logger.notice('hello world')
logger.warning('hello world')
logger.error('hello world')
logger.crit('hello world')
logger.alert('hello world')
logger.emerg('hello world')

Formatting

The loggers suppport the same formatting options and Node's util module.

var logger = require('bitters');
 
logger.debug('Hi, %s, my name is %', "Bill", variable)

The last argument to any of the log method can be a serialiable object and it will be included in the log data in an appropriate format.

var logger = require('bitters');
 
logger.debug("Dude, I just got some %s data", 'crazy', {key:'value'} )
