logginator

Installation

npm install logginator

Usage

var log = require('logginator')(config);
log.info("I am a log message");

Config

Optional. If left unspecified, logginator will default to console output.

To configure the backends, specify an array with the desired backend configurations, for example:

var log = require('logginator')([
  {
    "type": "console"
  }, {
    "type": "syslog"
  }
]);

console

To output logs to the console, use this configuration:

{
  "type": "console"
}

Console output has no configuration options.

syslog

To output logs to syslog, this configuration is sufficient:

{
  "type": "syslog"
}

Additional options are:

• appname: The name this process should use to identify itself to syslog. By default, logginator tries to deduce the name of the node project that uses logginator as a module.
• localhost: The hostname of the current machine, as sent to syslog. Defaults to os.hostname().
• facility: The facility, in syslog terminology, that the logger should log to. This concept only makes sense in a syslog setting, so refer to syslog documentation if you want to make an informed choice. Otherwise, stick with the default value, which is "local0".
• protocol: The protocol via which to log. The default, and recommended, value, is "unix", which makes logging go via Unix datagram sockets to the path specified in the path option. Other choices are "tcp4", "tcp6", "udp4" and "udp6", which all require host and port to be specified.
• path: The path to log to when using "unix" for protocol. If not set, logginator will try to deduce the default system log pipe by trying /dev/log and /var/run/log. If both of these fail, logginator will raise an exception.
• host and port: The host and port pair for the TCP or UDP log target if using any other protocol than "unix". Note that the target syslog daemon must be configured to accept connections on the specified protocol.
