Prerequisites

To complete the "Monitoring Ruby on Rails with Humio" tutorial, you will need the following prerequisites:

• A basic understanding of Ruby on Rails web development framework
• A working Ruby on Rails application
• A Humio account and access to the Humio web interface
• Basic knowledge of logging and monitoring concepts
• Familiarity with command-line interface (CLI) tools such as Terminal or Command Prompt
• Access to a text editor or integrated development environment (IDE) for editing code
• Familiarity with the Ruby programming language and its syntax
• Basic knowledge of Linux commands and shell scripting (optional)

Ruby on Rails Humio step by step setup and configuration

Integrating Humio into a Ruby on Rails project is a straightforward process that involves adding the Humio Ruby gem to your project and configuring it to send logs to your Humio account. The first step is to add the Humio Ruby gem to your project's Gemfile and run the bundle install command to install it.

# Gemfile
gem 'humio', '~> 1.0'

Once you have installed the Humio gem, you need to configure it to send logs to your Humio account. You can do this by adding the following configuration to your config/environments/production.rb file:

# config/environments/production.rb
config.logger = Humio::Logger.new(
  api_host: 'https://cloud.humio.com',
  ingest_token: 'YOUR_INGEST_TOKEN',
  data_space: 'YOUR_DATA_SPACE'
)

In the above code block, replace YOUR_INGEST_TOKEN and YOUR_DATA_SPACE with your Humio account's ingest token and data space, respectively. This configuration sets up the logger to send logs to your Humio account.

Once you have configured the logger, you can start logging events in your application using the logger object. For example, you can log an error event using the following code:

# app/controllers/application_controller.rb
class ApplicationController < ActionController::Base
  def index
    logger.error('An error occurred')
  end
end

In the above code block, the logger object logs an error event with the message "An error occurred". This event will be sent to your Humio account and can be viewed in the Humio web interface.

Overall, integrating Humio into a Ruby on Rails project involves adding the Humio Ruby gem, configuring the logger to send logs to your Humio account, and logging events using the logger object. By following these steps, you can easily monitor your Ruby on Rails application using Humio.

Humio configuration options in Ruby on Rails

Here are the Humio configuration options for Ruby on Rails integration with their short explanation:

• api_host: The URL of your Humio instance. Defaults to https://cloud.humio.com.
• ingest_token: The ingest token for your Humio account.
• data_space: The data space to send logs to in your Humio account.
• tags: A hash of tags to attach to each log event.
• batch_size: The maximum number of log events to send in a single batch. Defaults to 100.
• batch_interval: The maximum time to wait before sending a batch of log events. Defaults to 5 seconds.
• logger: The logger object to use for logging events. Defaults to Rails.logger.
• formatter: The log formatter to use for formatting log events. Defaults to Humio::Formatters::RailsFormatter.
• filter: A lambda function that filters log events before they are sent to Humio. Defaults to nil.
• async: Whether to send log events asynchronously. Defaults to true.
• async_queue_size: The maximum number of log events to queue for asynchronous sending. Defaults to 1000.
• async_queue_interval: The maximum time to wait before sending a batch of queued log events. Defaults to 1 second.

By configuring these options, you can customize the behavior of the Humio logger in your Ruby on Rails application. For example, you can set custom tags to attach to each log event, filter out certain log events, or adjust the batch size and interval for sending log events.
