Setup Requirements and Installation Steps

Here's a guide to the requirements and steps for setting up Datadog monitoring.

System Requirements

Before installing Datadog, make sure your system meets these minimum requirements:

Install Datadog Agent

Follow these steps to install the Datadog Agent on your system:

1. Windows Installation

Download the Agent installer from your Datadog account. Then, open PowerShell as Administrator and run the following commands:

$env:DD_API_KEY="your-api-key"
Start-Process -Wait msiexec -ArgumentList '/qn /i datadog-agent-7-latest.amd64.msi'

2. Linux Installation

For Linux systems, execute this command in your terminal:

DD_API_KEY=your-api-key DD_SITE="us" bash -c "$(curl -L https://s3.amazonaws.com/dd-agent/scripts/install_script.sh)"

3. Cloud Platform Integration

If you're integrating Datadog with a cloud platform like AWS, ensure you grant the necessary permissions. For example, use the following policy for AWS:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "cloudwatch:Get*",
                "cloudwatch:List*"
            ],
            "Resource": "*"
        }
    ]
}

Check Installation Status

Once installed, verify the Agent is running and connected:

• Agent Status Check
  • On Windows, run:
    & "C:\Program Files\Datadog\Datadog Agent\bin\agent\agent.exe" status
  • On Linux, execute:
    sudo datadog-agent status
• Platform Connection
  • Log in to your Datadog dashboard.
  • Go to Infrastructure > Hosts and confirm your systems appear.

The Agent should begin collecting metrics within about 5 minutes. If no data appears, check your firewall settings or ensure the Agent service is active.

Finally, test the setup by creating a CPU alert at 80%. Once metrics start flowing, you can proceed to connect your cloud services.

Connect Cloud Services to Datadog

Link your cloud services to Datadog by setting up authentication and organizing your resources effectively.

Add Cloud Provider Connections

Here's how to integrate AWS, Azure, and Google Cloud with Datadog:

1. AWS Integration

Set up an IAM role in your AWS account and configure the trust relationship with the following policy:

{
  "Version": "2012-10-17",
  "Principal": {
    "AWS": "arn:aws:iam::464622532012:root"
  },
  "Action": "sts:AssumeRole",
  "Condition": {
    "StringEquals": {
      "sts:ExternalId": "[YOUR-EXTERNAL-ID]"
    }
  }
}

In your Datadog dashboard, go to Integrations > AWS, and provide your AWS Account ID and External ID.

2. Azure Integration

Register an app in Azure and assign it the Reader role at the subscription level. You'll need these details:

• Application (client) ID
• Directory (tenant) ID
• Client Secret

Enter this information in the Azure integration tile on Datadog's Integration page.

3. Google Cloud Integration

Create a service account and assign these roles: Compute Viewer, Monitoring Viewer, and Cloud Asset Viewer.

Download the JSON key file and upload it through Datadog's GCP integration page.

Once the cloud providers are connected, organize resources for better monitoring by tagging them.

Set Up Resource Tags

Tagging your resources helps streamline monitoring. Use the following structure:

Best practices for tagging:

• Keep naming conventions consistent across all cloud providers.
• Apply tags during resource creation using Infrastructure as Code tools.
• Enforce automatic tagging with cloud provider policies.
• Use tag-based views in Datadog dashboards to simplify monitoring.

For automated tagging in Datadog, configure rules like this:

# Example tag mapping rule
mapping:
  - name: "service"
    pattern: "^(?P<service>[^-]+).*$"
    apply_to: "host"

This rule extracts service names from resource identifiers and assigns them as tags.

Set Up Monitoring and Alerts

Monitor and Alert Basics

Start by identifying the key performance indicators (KPIs) that matter most for your cloud infrastructure. Tools like Datadog can track these metrics in real time and trigger alerts when specific thresholds are crossed.

Here are the core components of monitoring:

• Metrics: Measurable data points such as CPU usage, memory consumption, and response times.
• Thresholds: Predefined values that, when exceeded, activate an alert.
• Alert Priority: Levels of urgency that dictate how quickly and to whom notifications are sent.

These elements form the groundwork for creating detailed configurations.

Set Up Metric Monitors

Focus on the most critical metrics for your infrastructure and use the following recommended thresholds to guide your setup:

To set up a metric monitor, follow these steps:

1. Go to Monitors > New Monitor > Metric in your monitoring tool.
2. Use the query builder to select the metric you want to monitor.
3. Define the alert conditions and thresholds based on your needs.
4. Specify the evaluation window and configure how the monitor handles missing data.
5. Add a notification message and choose the recipients who should be alerted.

For more complex scenarios, you can use composite monitors to combine multiple metrics into a single alert. Here's an example:

# Example composite monitor
avg(last_5m):avg:system.cpu.user{*} > 80 && 
avg(last_5m):avg:system.memory.used{*} > 85

Once your metric monitors are in place, you can fine-tune the alert settings for better alignment with your team's workflow.

Configure Alert Settings

After setting up metric monitors, customize alert settings to ensure they fit your team's processes and priorities.

1. Notification Channels
   • Primary: Slack channels for team-wide visibility.
   • Secondary: Email notifications for lower-priority updates.
   • Urgent: PagerDuty or SMS for critical, time-sensitive issues.
2. Time-Based Routing Adjust alert routing based on time zones to ensure the right team members are notified during their working hours. For example:

   # Alert routing example
   notifications:
     business_hours: "09:00-17:00 America/New_York"
     primary_team: "@slack-ops-team"
     after_hours: "@pagerduty-oncall"
   

3. Alert Message Template Craft clear and actionable alert messages to reduce response times. Here's a sample format:

   [SEVERITY] Monitor Alert: {{monitor.name}}
   Metric: {{metric.name}}
   Value: {{value}} {{unit}}
   Threshold: {{threshold}}
   Environment: {{host.environment}}
   Actions: [Runbook Link] [Dashboard Link]
   

With these settings, your alerts will be well-organized, actionable, and tailored to your team's requirements.

Create and Modify Dashboards

Build Monitoring Dashboards

To create a dashboard that works well, group related metrics together. Start by navigating to Dashboards > New Dashboard in your Datadog console.

1. Layout and Structure

Organize metrics into logical sections for clarity:

- System Health: CPU, Memory, Disk Space
- Application Performance: Response Times, Error Rates, Request Volume
- Business Metrics: Transactions, Active Users, Revenue Impact

2. Widget Selection

Choose the right widget type for each metric:

3. Data Visualization

Assign clear and specific queries to your widgets for accurate data representation:

# Example widget query
avg:system.cpu.user{environment:production} by {host}.rollup(avg, 60)

Once your dashboard layout is complete, fine-tune the settings to suit your team's needs.

Adjust Dashboard Settings for Teams

After setting up your custom dashboard layout, refine its settings to enhance team collaboration and usability.

1. Time Zone Configuration

Set a time zone and refresh settings to keep dashboards relevant:

dashboard_settings:
  timezone: "America/New_York"
  refresh_interval: 300
  default_timeframe: "1h"

2. Access Controls

Define permissions to ensure the right people have appropriate access:

3. Template Variables

Use template variables to make dashboards dynamic and reusable:

template_variables:
  - name: "environment"
    prefix: "env"
    default: "production"
  - name: "service"
    prefix: "service"
    default: "all"

Keep dashboards concise by limiting them to 25–30 widgets. Critical metrics should update every 30 seconds, while less urgent ones can refresh every 5 minutes.

SMB Monitoring Guidelines

These SMB-focused tips build on your existing Datadog setup to improve alerts, manage costs, and strengthen security measures.

Improve Alert and Dashboard Usage

Set alert thresholds carefully to ensure they remain effective and avoid overwhelming your team.

To keep alerts aligned with your team’s capacity, consider this configuration for routing and escalation:

alert_settings:
  business_hours: "9:00 AM - 5:00 PM EST"
  on_call_rotation: true
  escalation_delay: 30
  recovery_window: 15

Once alerts are fine-tuned, focus on keeping costs under control as your infrastructure expands.

Control Costs and Growth

As your monitoring needs grow, take steps to manage Datadog costs effectively:

• Resource Tagging Strategy: Use a clear tagging system to track usage and allocate resources efficiently.

tag_structure:
  environment: [prod, staging, dev]
  team: [backend, frontend, ops]
  cost_center: [infrastructure, application]

• Optimize Metric Collection: Prioritize essential metrics to reduce unnecessary data collection.

• Custom Metrics Management: Regularly review and adjust custom metrics to avoid waste.

metric_review:
  frequency: monthly
  retention_rules:
    unused_metrics: archive after 30 days
    low_value_metrics: evaluate quarterly

By managing costs effectively, you’ll have more resources to dedicate to critical security measures.

Meet Security Standards

Strengthen your security practices while ensuring compliance with U.S. regulations using Datadog's tools.

• Access Control Configuration: Implement role-based access control (RBAC) to define permissions clearly.

security_roles:
  admin:
    permissions: ["write_all", "read_all"]
    mfa_required: true
  developer:
    permissions: ["read_all", "write_logs"]
    ip_restriction: true

• Data Privacy Settings: Set up configurations to meet compliance requirements.

• Audit Trail Setup: Enable audit logging to track key events and changes.

audit_settings:
  log_retention: 365
