This guide ensures a smooth integration, helping you monitor and optimize your Engine Yard environment effectively.

Setup Requirements for Engine Yard

System Requirements Check

Before diving in, make sure your system meets these baseline requirements:

• Memory: At least 1GB of RAM (2GB is better if you’re running a production environment).
• CPU: A minimum of 1 core, though 2 cores are recommended for production.
• Storage: You’ll need 350MB of free disk space to install the agent.
• Operating System: Either Ubuntu 18.04 LTS or newer, or Amazon Linux 2.

Also, ensure there’s enough capacity to handle both the Datadog agent and your applications without running into resource issues.

Access and Security Setup

Once your system is ready, it’s time to configure access and security settings to ensure smooth operation.

Network Configuration

Your Engine Yard instances must have outbound access on port 443 to these Datadog endpoints:

• api.datadoghq.com (for the US region)
• agent-intake.logs.datadoghq.com
• process.datadoghq.com

AWS IAM Permissions

Set up an IAM role with read-only access for monitoring. This role should include permissions for:

• CloudWatch metrics
• EC2 instance monitoring
• RDS monitoring
• ElastiCache monitoring

Required Software List

To ensure everything runs smoothly, your Engine Yard environment needs the following software:

Database Monitoring Setup

For database monitoring, set up dedicated read-only users. If you’re working with MySQL, you can use the following SQL command:

GRANT SELECT, PROCESS, REPLICATION CLIENT ON *.* TO 'datadog'@'localhost';

To keep database performance steady while collecting metrics, limit monitoring connections to 3–5. This strikes a good balance between data collection and system efficiency.

Datadog Agent Installation Steps

SSH Installation Guide

To get started, access your instance via SSH. Once connected, download and run the installation script using your API key. After that, simply start the agent.

For deploying the Datadog agent across multiple instances, you can use the Datadog Chef cookbook. This tool simplifies the process, ensuring all instances are set up consistently with minimal effort.

Agent Configuration Settings

Once the agent is installed, you’ll need to adjust the configuration. Open the datadog.yaml file and update it with the following settings:

# Basic agent configuration
hostname: "your-engine-yard-instance"
tags:
  - environment:production
  - service:web
  - region:us-east

# Performance settings
process_config:
  enabled: true
logs_enabled: true
apm_config:
  enabled: true

For more refined control, use the node['datadog']['extra_config'] attribute. This method allows you to add custom settings without altering the core configuration file, giving you flexibility to fine-tune the agent’s behavior.

Integration Settings

Here’s a quick overview of integration options:

After configuring the agent, it's time to verify everything is working as expected.

Installation Check

1. Verify Agent Status
   Run the following command to ensure the agent is active and reporting:

   sudo datadog-agent status
   

   Check the Datadog dashboard to confirm that metrics like CPU, memory, disk usage, and any custom or integration metrics are being tracked.
2. Test Log Collection
   Logs should start appearing in your Datadog dashboard within 5 minutes of installation. This confirms that log collection is functioning correctly.

If you run into any issues during installation, you can troubleshoot using the agent's debug mode:

sudo datadog-agent diagnose

This command helps identify and resolve common problems, ensuring a smooth setup process.

Monitoring and Alert Configuration

Dashboard Setup for Engine Yard

After verifying the Datadog agent, the next step is configuring dashboards and alerts to keep tabs on Engine Yard's performance. Start by setting up a dashboard to track key metrics that reflect the health and efficiency of your system.

Here are the essential metrics to include:

# Key Engine Yard Metrics
- CPU Utilization
- Memory Usage
- Disk Space
- Network Traffic
- Application Response Times
- Error Rates

For each metric, add widgets to your dashboard. Use time-series graphs to visualize both real-time performance and historical trends. This setup provides a clear overview of your system's behavior over time.

Alert Setup Guide

When creating alerts, focus on work metrics - the ones that measure how effectively your system is performing its tasks - rather than just resource usage.

"You only want to get alerted on work metrics. In other words, you want to get alerted on things that measure how useful your system is." - Alexis Lê-Quôc, co-founder and CTO of Datadog

Set specific thresholds for critical metrics to ensure timely alerts:

Once you've defined these thresholds, configure notifications to ensure your team can respond promptly to any issues.

Alert Notification Setup

Set up notification channels through the Datadog interface to make sure alerts reach the right people at the right time:

• Email Notifications: Create escalation tiers based on the severity of the alert. Assign different email groups for various alert types to streamline responses.
• Integration Alerts: Connect Datadog with your team's communication tools for seamless notifications:

• No Data Alerts: Activate these alerts for critical metrics to detect connectivity issues or agent failures quickly.

"Alerting is at the heart of proactive system monitoring, especially when managing dynamic environments that involve complex infrastructure." - Siddarth Jain

To make alerts actionable, use templates that include:

• The conditions that triggered the alert
• Details about the affected system components
• Suggested initial steps for troubleshooting
• Links to related runbooks
• Escalation contact information

This approach ensures your team is always prepared to address issues efficiently.
