Common Symptoms and Quick Fixes

How to Detect Infrastructure as Code Drift

Automatic Detection with Zuzia.app

Zuzia.app automatically monitors infrastructure as code state on your servers through its agent-based system. The system:

• Checks infrastructure state every few minutes automatically
• Stores all infrastructure state data historically in the database
• Sends alerts when drift or configuration mismatches are detected
• Tracks infrastructure changes over time
• Uses AI analysis (full package) to detect unusual patterns

You'll receive notifications via email or other configured channels when infrastructure drift is detected, allowing you to respond quickly before configuration inconsistencies cause problems.

Manual Detection Methods

You can also check for infrastructure drift manually using commands that Zuzia.app can execute:

# Check for infrastructure drift
terraform plan
terraform show

# Validate infrastructure code
terraform validate
terraform fmt -check

# Check infrastructure state
terraform state list
terraform state show <resource>

# Compare with remote state
terraform refresh

Add these commands as scheduled tasks in Zuzia.app to monitor infrastructure drift continuously and receive alerts when drift is detected.

Common Causes of Infrastructure as Code Drift

FAQ: Common Questions About Infrastructure as Code Drift

How do I know if my infrastructure has drifted?

Zuzia.app automatically monitors infrastructure state and sends alerts when drift is detected. You can also check manually using terraform plan to see changes not in code, or terraform show to review current state. Symptoms include unexpected changes in terraform plan or configuration mismatches.

What should I do immediately when infrastructure drift is detected?

When infrastructure drift is detected, immediately run terraform plan to see changes, refresh state with terraform refresh to sync with reality, review changes before applying, and apply terraform plan to restore state if safe. Use Zuzia.app to identify drift quickly.

Can infrastructure drift cause service disruptions?

Yes, infrastructure drift can cause service disruptions if configuration changes break services, resources are modified incorrectly, or infrastructure state becomes inconsistent. It's important to monitor infrastructure drift continuously and reconcile state promptly.

How can Zuzia.app help prevent infrastructure drift?

Zuzia.app helps prevent infrastructure drift by monitoring infrastructure state continuously, alerting you before drift becomes critical, tracking infrastructure changes over time, and using AI analysis (full package) to detect patterns and predict potential problems. You can also use Zuzia.app to detect manual changes and configuration mismatches.

Does AI analysis help with infrastructure drift problems?

Yes, if you have Zuzia.app's full package, AI analysis can detect infrastructure patterns, identify drift sources, predict potential infrastructure problems before they occur, suggest ways to reconcile state, and correlate infrastructure changes with other metrics to identify root causes.

Can I monitor infrastructure across multiple environments simultaneously?

Yes, Zuzia.app allows you to add multiple servers and monitor infrastructure across all of them simultaneously. Each server has its own infrastructure metrics and can be configured independently. This helps you identify which environments need attention and track infrastructure across your organization.

How often should I check for infrastructure drift?

Zuzia.app checks infrastructure state automatically every few minutes. For critical production infrastructure, this frequency is usually sufficient. You can also add custom commands to check infrastructure state more frequently if needed. The key is continuous monitoring rather than occasional checks, which Zuzia.app provides automatically.

What's the difference between infrastructure drift and configuration drift?

Infrastructure drift refers to differences between infrastructure code and actual infrastructure state. Configuration drift refers to differences between configuration files and actual system configuration. Both should be monitored and prevented.

Can I set up automatic actions when infrastructure drift is detected?

Yes, Zuzia.app allows you to configure automatic actions when infrastructure drift is detected. You can set up terraform plan execution, state refresh, team notifications, and other automated responses. This helps you respond to infrastructure drift automatically without manual intervention.

How does historical infrastructure data help with prevention?

Historical infrastructure data collected by Zuzia.app shows infrastructure state trends over time, allowing you to identify drift patterns, predict when infrastructure problems might occur, plan infrastructure changes proactively, and make data-driven decisions about infrastructure management. The AI analysis (full package) can automatically detect trends and suggest when infrastructure reconciliation might be needed.
