• A Google Cloud Platform account with billing enabled
• A basic understanding of Google Cloud Platform services, including Compute Engine and Cloud Monitoring
• A local development environment set up with Ruby on Rails and the necessary dependencies installed

Ruby on Rails Google Cloud Monitoring step by step setup and configuration

Integrating Google Cloud Monitoring into a Ruby on Rails project is a straightforward process. The first step is to create a Google Cloud Platform project and enable the Cloud Monitoring API. Once this is done, you can install the google-cloud-monitoring gem in your Ruby on Rails project. This gem provides a Ruby client library for the Cloud Monitoring API, allowing you to send metrics and create custom dashboards.

To send metrics to Google Cloud Monitoring, you can use the google-cloud-monitoring gem's Google::Cloud::Monitoring::MetricService class. This class provides methods for creating and updating metrics, as well as sending metric data. For example, to send a custom metric for the number of requests to a specific endpoint, you can use the following code:

require "google/cloud/monitoring"

metric_service = Google::Cloud::Monitoring::MetricService.new
project_name = "projects/my-project"

metric_service.create_metric_descriptor(
  project_name,
  {
    type: "custom.googleapis.com/requests",
    metric_kind: :DELTA,
    value_type: :INT64,
    unit: "1",
    description: "Number of requests to a specific endpoint",
    labels: [
      { key: "endpoint", value_type: :STRING, description: "The endpoint name" }
    ]
  }
)

metric_service.write_time_series(
  project_name,
  [
    {
      metric: {
        type: "custom.googleapis.com/requests",
        labels: { endpoint: "/api/v1/users" }
      },
      resource: {
        type: "global",
        labels: {}
      },
      points: [
        {
          interval: {
            end_time: Time.now.to_i,
            start_time: (Time.now - 60).to_i
          },
          value: { int64_value: 100 }
        }
      ]
    }
  ]
)

This code creates a custom metric descriptor for the number of requests to a specific endpoint and sends a time series data point for the /api/v1/users endpoint with a value of 100.

To create custom dashboards in Google Cloud Monitoring, you can use the google-cloud-monitoring gem's Google::Cloud::Monitoring::DashboardService class. This class provides methods for creating and updating dashboards, as well as adding charts and widgets. For example, to create a custom dashboard for your Ruby on Rails application, you can use the following code:

require "google/cloud/monitoring"

dashboard_service = Google::Cloud::Monitoring::DashboardService.new
project_name = "projects/my-project"

dashboard_service.create_dashboard(
  project_name,
  {
    display_name: "Ruby on Rails Application",
    grid_layout: {
      columns: 2,
      widgets: [
        {
          title: "Requests per Minute",
          chart_options: {
            mode: :STACKED,
            x_axis_options: { mode: :EXPANDED },
            y_axis_options: { label: "Requests per Minute" }
          },
          data_source_options: {
            time_series_query: {
              time_series_filter: {
                metric_type: "custom.googleapis.com/requests",
                label_filter: "endpoint=\"/api/v1/users\""
              },
              time_range: {
                end_time: Time.now.to_i,
                start_time: (Time.now - 3600).to_i
              },
              aggregation: {
                per_series_aligner: :ALIGN_RATE,
                cross_series_reducer: :REDUCE_SUM,
                alignment_period: { seconds: 60 }
              }
            }
          }
        }
      ]
    }
  }
)

This code creates a custom dashboard with a single chart showing the number of requests per minute for the /api/v1/users endpoint.

Overall, integrating Google Cloud Monitoring into a Ruby on Rails project is a simple process that can provide valuable insights into your application's performance. By sending metrics and creating custom dashboards, you can quickly identify and troubleshoot issues, ensuring that your application is performing at its best.
