Similar Npm Packages to winston-loggly-bulk

winston-loggly-bulk is a transport for the popular logging library Winston, specifically designed to send logs to Loggly in bulk. This package allows developers to efficiently manage and send log messages to Loggly, a cloud-based log management service, enabling better monitoring and analysis of application logs. By using winston-loggly-bulk, developers can take advantage of Winston's powerful logging capabilities while seamlessly integrating with Loggly's logging infrastructure.

While winston-loggly-bulk is a robust option for logging to Loggly, there are alternatives available that may suit different needs:

  • loggly-jslogger is a lightweight JavaScript logger for sending logs to Loggly. Unlike winston-loggly-bulk, which is built on top of the Winston logging framework, loggly-jslogger is a standalone library that provides a straightforward way to log messages directly to Loggly. This makes it a good choice for projects that do not require the full capabilities of Winston or for developers looking for a simpler solution for logging to Loggly.

Similar Npm Packages to loggly-jslogger

loggly-jslogger is a JavaScript logging library designed to send logs to Loggly, a cloud-based log management service. This package allows developers to easily integrate logging into their applications, ensuring that important events and errors are captured and sent to a centralized logging service for analysis and monitoring. While loggly-jslogger is a great choice for applications that specifically want to utilize Loggly, there are several other logging libraries available that offer different features and capabilities. Here are a few alternatives:

  • bunyan is a simple and fast JSON logging library for Node.js applications. It provides a structured logging format, making it easy to filter and query logs. Bunyan supports log levels, streams, and serializers, allowing developers to customize their logging output. It is particularly useful for server-side applications that require detailed and structured logs for debugging and monitoring.
  • debug is a lightweight logging utility that allows developers to enable or disable logging based on namespaces. It is commonly used in Node.js and browser applications for debugging purposes. With debug, you can control the verbosity of logs without modifying the code, making it a flexible choice for development and production environments.
  • log4js is a logging library inspired by the popular log4j framework. It provides a variety of appenders (e.g., console, file, and SMTP) and supports log levels, categories, and layouts. Log4js is suitable for both client-side and server-side applications, offering a comprehensive solution for managing logs in different environments.
  • loglevel is a minimalistic logging library that provides a simple API for logging messages at different levels (trace, debug, info, warn, error). It is lightweight and easy to use, making it a good choice for projects that require basic logging functionality without the overhead of more complex libraries.
  • morgan is an HTTP request logger middleware for Node.js applications. It is commonly used with Express.js to log incoming requests and their details. Morgan provides predefined formats for logging and can be easily customized to suit the needs of your application.

README for winston-loggly-bulk

winston-loggly-bulk

A Loggly transport for winston.

Version npmnpm Downloads

NPM

A client implementation for Loggly in node.js. Check out Loggly's Node logging documentation for more.

Usage

  var winston = require('winston');

  //
  // Requiring `winston-loggly-bulk` will expose
  // `winston.transports.Loggly`
  //
  var {Loggly} = require('winston-loggly-bulk');

  winston.add(new Loggly({options}));

The Loggly transport is based on Nodejitsu's node-loggly implementation of the Loggly API. If you haven't heard of Loggly before, you should probably read their value proposition. The Loggly transport takes the following options.

  • subdomain: The subdomain of your Loggly account. [required]
  • token: The access token (previously inputToken) [required]
  • auth: The authentication information for your Loggly account.
  • json: If true, messages will be sent to Loggly as JSON.
  • tags: An array of tags to send to loggly.
  • isBulk: If true, sends messages using bulk url
  • stripColors: Strip color codes from the logs before sending
  • bufferOptions: Buffer options has two configurations.
    • size: Number of logs to be buffered.
    • retriesInMilliSeconds: Time in milliseconds to retry sending buffered logs.
  • timestamp: If false, library will not include timestamp in log events.
    • Note: Library includes timestamp by default when we do not set timestamp option.
  • networkErrorsOnConsole: The library keep track of different network errors and can log them to console. By default, logging errors on console is disabled and can be enabled easily by setting this parameter's value to true. If true, all the network errors will be logged to console.

Sample Working Code Snippet

var winston  = require('winston');
var { Loggly } = require('winston-loggly-bulk');

winston.add(new Loggly({
    token: "TOKEN",
    subdomain: "SUBDOMAIN",
    tags: ["Winston-NodeJS"],
    json: true
}));

winston.log('info', "Hello World from Node.js!");

Buffer Support

This library has buffer support during temporary network outage. User can configure size of buffer (no. of logs to be stored during network outage).

Add these below configuration in code snippet to override the default values of buffer option size and retriesInMilliSeconds.

bufferOptions: {
  size: 1000,
  retriesInMilliSeconds: 60 * 1000
}
  • Note: The default value of buffer size and retries in milliseconds are 500 and 30000 (30 seconds) respectively.

Flush logs and exit

Our library uses ajax requests to send logs to Loggly, and as ajax requests take time to complete, logs can be lost when process.exit() is called because it forces an immediate exit. To exit gracefully and ensure that the last logs get to Loggly, we created a function called flushLogsAndExit(). It waits for 10 seconds and then calls process.exit() itself. This allows enough time for the logs to be sent to Loggly.

Here is an example of how to use the method:

var winston = require('winston');
var { flushLogsAndExit } = require('winston-loggly-bulk');

winston.log("info", "Hello World from Node.js!");
flushLogsAndExit();

Motivation

tldr;?: To break the winston codebase into small modules that work together.

The winston codebase has been growing significantly with contributions and other logging transports. This is awesome. However, taking a ton of additional dependencies just to do something simple like logging to the Console and a File is overkill.

Installation

  npm install winston-loggly-bulk

Note: If you are using npm version 2, please run the below command:

  npm install winston-loggly-bulk winston
