Applying the Script in a DevOps Environment : Alerts and Monitoring, Daily Reports, Documentation and Review using Ruby script

Applying the Script in a DevOps Environment

Alerts and Monitoring:

• The Ruby script can be used to send daily reports on the system's status, such as resource usage, service health, and application performance.
• It can be integrated with monitoring tools like Prometheus or Nagios to automatically send alerts when issues occur.

Daily Reports:

• Send reports on deployments, building new versions of the application, and quality tests.
• It can send summaries of Continuous Integration (CI) and Continuous Delivery (CD) statuses using tools like Jenkins or GitLab CI/CD.

Documentation and Review:

• Daily documentation reports can be sent to team members about the activities performed and any issues encountered.
• It helps in tracking and reviewing changes happening in the infrastructure or applications.

Example of Using the Script to Send a Report from Jenkins

If you are using Jenkins, you can set up a job to run the script after each build or deployment and send a status report.

Setting Up a Jenkins Job to Run the Script

Creating a New Job:

• Open Jenkins and create a new project (Freestyle Project).
• In the "Build" section, add a new "Execute Shell" step.

Adding the Script:

• In "Execute Shell," add the command to run your script:

  ruby /path/to/your/send_report.rb

Running the Job After Each Build:

• You can set up a trigger to build the project automatically after each code change, or schedule a build to run the job daily.

Integrating the Script with Other Monitoring Tools

You can modify the script to fetch data from monitoring tools like Prometheus or Nagios and send it as part of the report.

Example of Fetching Data from Prometheus

require 'net/http'
require 'json'
require 'mail'

# Email settings
options = {
  address: 'smtp.your-email-provider.com',
  port: 587,
  user_name: '[email protected]',
  password: 'your-email-password',
  authentication: 'plain',
  enable_starttls_auto: true
}

Mail.defaults do
  delivery_method :smtp, options
end

# Fetching data from Prometheus
uri = URI('http://your-prometheus-server/api/v1/query?query=up')
response = Net::HTTP.get(uri)
result = JSON.parse(response)

# Setting up the email message
mail = Mail.new do
  from     '[email protected]'
  to       '[email protected]'
  subject  'Daily Report from Prometheus'
  body     "System Status:\n\n#{result['data']['result'].map { |r| "#{r['metric']['instance']}: #{r['value'][1]}" }.join("\n")}"
end

begin
  mail.deliver!
  puts "Email sent successfully"
rescue => e
  puts "Failed to send email. Reason: #{e.message}"
end

By following these steps, you can use the script as part of DevOps tasks, contributing to automation, enhanced monitoring, and better flow management.
