pino-socket

pino-socket

This module provides a "transport" for pino that simply forwards messages to an arbitrary socket. The socket can be UDPv4 or TCPv4. The module can echo the received logs or work silently.

You should install pino-socket globally for ease of use:

$ npm install --production -g pino-socket

Usage

Given an application foo that logs via pino, and a system that collects logs on port UDP 5000 on IP 10.10.10.5, you would use pino-socket like so:

$ node foo | pino-socket -a 10.10.10.5 -p 5000

Options

• --settings (-s): read settings from a JSON file (switches take precedence)
• --address (-a): the address for the destination socket. Default: 127.0.0.1.
• --mode (-m): either tcp or udp. Default: udp.
• --port (-p): the port for the destination socket. Default: 514.
• --reconnect (-r): enable reconnecting to dropped TCP destinations. Default: off
• --reconnectTries <n> (-t <n>): set number (<n>) of reconnect attempts before giving up. Default: infinite
• --echo (-e): echo the received messages to stdout. Default: enabled.
• --no-echo (-ne): disable echoing received messages to stdout.

Settings JSON File

The --settings switch can be used to specify a JSON file that contains a hash of settings for the the application. A full settings file is:

{
  "address": "127.0.0.1",
  "port": 514,
  "mode": "tcp",
  "reconnect": true,
  "reconnectTries": 20,
  "echo": false
}

Note that command line switches take precedence over settings in a settings file. For example, given the settings file:

{
  "address": "10.0.0.5",
  "port": 514
}

And the command line:

$ yes | pino-socket -s ./settings.json -p 1514

The connection will be made to address 10.0.0.5 on UDP port 1514.
