bunyan-loggly

A bunyan stream to send logs through to loggly.

Configuration

bunyan-loggly uses node-loggly under the hood. As such, when configuring bunyan-loggly as a stream for bunyan, you need to pass in the standard and required node-loggly configuration object.

For example:

{
	token: "your-really-long-input-token",
	subdomain: "your-subdomain"
}

Usage

This is a basic usage example.

var bunyan = require('bunyan');
var Bunyan2Loggly = require('bunyan-loggly');
var logglyConfig = {
    token: 'your-account-token',
    subdomain: 'your-sub-domain',
};

var logglyStream = new Bunyan2Loggly(logglyConfig);

// create the logger
var logger = bunyan.createLogger({
    name: 'logglylog',
    streams: [
        {
            type: 'raw',
            stream: logglyStream,
        },
    ],
});

logger.info({});

Please note: you MUST define type: 'raw' as bunyan-loggly expects to receive objects so that certain values can be changed as required by loggly (i.e. time to timestamp).

Buffering

bunyan-loggly supports basic buffering and when setup, will only send your logs through to loggly on every x logs. To setup buffering, just pass an integer as the second parameter when creating a new instance of Bunyan2Loggly:

var bunyan = require('bunyan');
var Bunyan2Loggly = require('bunyan-loggly');
var logglyConfig = {
    token: 'your-account-token',
    subdomain: 'your-sub-domain',
};
var bufferLength = 5;

var logglyStream = new Bunyan2Loggly(logglyConfig, bufferLength);

// create the logger
var logger = bunyan.createLogger({
    name: 'logglylog',
    streams: [
        {
            type: 'raw',
            stream: logglyStream,
        },
    ],
});

logger.info({});    // won't send to loggly
logger.info({});    // won't send to loggly
logger.info({});    // won't send to loggly
logger.info({});    // won't send to loggly
logger.info({});    // will send to loggly
logger.info({});    // won't send to loggly

Buffer Timeout

When buffering, a timeout can be provided to force flushing the buffer after a period of time. To setup a flush timeout, pass a timeout value (in ms) as the third parameter when creating a new instance of Bunyan2Loggly:

var bunyan = require('bunyan');
var Bunyan2Loggly = require('bunyan-loggly');
var logglyConfig = {
    token: 'your-account-token',
    subdomain: 'your-sub-domain',
};
var bufferLength = 5;
var bufferTimeout = 500;

var logglyStream = new Bunyan2Loggly(logglyConfig, bufferLength, bufferTimeout);

// create the logger
var logger = bunyan.createLogger({
    name: 'logglylog',
    streams: [
        {
            type: 'raw',
            stream: logglyStream,
        },
    ],
});

logger.info({});    // will be sent to loggly in 500ms if buffer threshold is not reached

Loggly request information

Each time log content is sent to loggly, the result of this request will be passed to the optional callback paramer logglyCallback

var bunyan = require('bunyan');
var Bunyan2Loggly = require('bunyan-loggly');
var logglyConfig = {
    token: 'your-account-token',
    subdomain: 'your-sub-domain',
};

function logglyCallback(error, result, content) {
    // handle loggly callback
}

var logglyStream = new Bunyan2Loggly(logglyConfig, null, null, logglyCallback);
