Prerequisites

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

• A Microsoft Azure account with an active subscription
• A Ruby on Rails application that you want to monitor
• The Azure CLI (Command Line Interface) installed on your local machine
• The Azure Monitor Agent installed on the virtual machine or server where your Ruby on Rails application is hosted
• Basic knowledge of Ruby on Rails and web application development
• Basic knowledge of Azure Monitor and its monitoring capabilities

It is recommended that you have a basic understanding of Azure Monitor and its monitoring capabilities before starting this tutorial. Additionally, you should have a basic understanding of Ruby on Rails and web application development, as we will be configuring Azure Monitor to monitor a Ruby on Rails application. Finally, you will need to have the Azure CLI and Azure Monitor Agent installed on your local machine and virtual machine/server, respectively, to complete the tutorial.

Ruby on Rails Azure Monitor step by step setup and configuration

Integrating Azure Monitor into a Ruby on Rails project involves several steps. Firstly, you need to create an Azure Monitor resource in your Azure account. This resource will be used to collect and analyze telemetry data from your Ruby on Rails application. To create an Azure Monitor resource, you can use the Azure CLI command az monitor create.

az monitor create --resource-group <resource-group-name> --name <monitor-name> --location <location>

Next, you need to configure your Ruby on Rails application to send telemetry data to the Azure Monitor resource. This can be done using the Azure Application Insights Ruby gem. To install the gem, add the following line to your Gemfile:

gem 'application_insights'

Then, run bundle install to install the gem. Once the gem is installed, you can configure it to send telemetry data to your Azure Monitor resource by adding the following lines to your config/application.rb file:

require 'application_insights'
config.logger = ApplicationInsights::Logger.new

Finally, you can use the Azure Monitor resource to monitor your Ruby on Rails application by creating custom metrics and alerts. Custom metrics can be created using the Azure Monitor REST API or the Azure CLI. For example, to create a custom metric using the Azure CLI, you can use the following command:

az monitor metrics alert create --resource-group <resource-group-name> --name <alert-name> --condition "avg(request.duration) > 500" --description "High response time" --severity 3 --window-size 5m --evaluation-frequency 1m --action email <email-address>

This command creates an alert that triggers when the average response time of your Ruby on Rails application exceeds 500 milliseconds. The alert sends an email notification to the specified email address.

In summary, integrating Azure Monitor into a Ruby on Rails project involves creating an Azure Monitor resource, configuring the Azure Application Insights Ruby gem to send telemetry data to the resource, and creating custom metrics and alerts to monitor the performance and health of your Ruby on Rails application.

Azure Monitor configuration options in Ruby on Rails

Here are the Azure Monitor configuration options for Ruby on Rails integration:

• Azure Monitor resource creation: Create an Azure Monitor resource in your Azure account to collect and analyze telemetry data from your Ruby on Rails application.
• Azure Application Insights Ruby gem: Use the Azure Application Insights Ruby gem to configure your Ruby on Rails application to send telemetry data to your Azure Monitor resource.
• Custom metrics: Create custom metrics to monitor specific aspects of your Ruby on Rails application, such as response time, error rate, and throughput.
• Alerts: Create alerts to notify you when specific conditions are met, such as when the response time of your Ruby on Rails application exceeds a certain threshold or when the error rate exceeds a certain percentage.
• Dashboards: Create dashboards to visualize the performance and health of your Ruby on Rails application, using metrics and other telemetry data collected by Azure Monitor.
• Log Analytics: Use Log Analytics to collect and analyze log data from your Ruby on Rails application, and gain insights into application behavior and performance.
• Application Insights API: Use the Application Insights API to retrieve telemetry data from your Ruby on Rails application, and integrate it with other tools and services.
• Azure Functions: Use Azure Functions to create serverless functions that can be triggered by events in your Ruby on Rails application, such as when an alert is triggered or when a custom metric exceeds a certain threshold.
• Azure Automation: Use Azure Automation to automate common tasks and processes related to monitoring your Ruby on Rails application, such as creating alerts and dashboards, and analyzing telemetry data.
