## GCP Integration Concepts

### Authentication Methods

**STS-Based Authentication with Workload Identity (V2 - Recommended)**:
- Uses GCP Workload Identity Federation
- Most secure method with short-lived tokens
- No long-lived service account keys
- Required for V2 API
- Steps:
  1. Create Datadog GCP delegate account via API
  2. Create GCP service account in your project
  3. Grant service account required permissions
  4. Configure Workload Identity binding between Datadog delegate and your service account
  5. Register service account with Datadog

**Service Account Key Authentication (V1 - Deprecated)**:
- Uses service account JSON key file
- Less secure, requires key management
- Being phased out in favor of Workload Identity
- Not recommended for new integrations

### Monitored Resource Types

**GCE Instances (gce_instance)**:
- Google Compute Engine virtual machines
- Filter by labels (tags)
- Includes instance metrics and metadata

**Cloud Functions (cloud_function)**:
- Google Cloud Functions (1st and 2nd gen)
- Filter by labels
- Includes invocation metrics and logs

**Cloud Run Revisions (cloud_run_revision)**:
- Cloud Run service revisions
- Filter by labels
- Includes request metrics and container stats

### Metrics Configuration

**Metric Namespace Configs**:
- Control which GCP services send metrics to Datadog
- Disable entire namespaces to reduce metric volume
- Apply metric-level filters within namespaces
- Examples:
  - `compute`: GCE, GKE metrics
  - `pubsub`: Pub/Sub metrics
  - `aiplatform`: AI Platform metrics
  - `storage`: Cloud Storage metrics
  - `cloudsql`: Cloud SQL metrics

**Metric Filters**:
- Include/exclude specific metrics within a namespace
- Supports wildcard patterns
- Examples:
  - `"snapshot.*"`: Include all snapshot metrics
  - `"!*_by_region"`: Exclude all per-region metrics

**Monitored Resource Filters**:
- Limit resource collection based on GCP labels (tags)
- Applied per resource type
- Reduces metric volume and costs
- Example: Only collect GCE metrics for `env:production` label

### Security Configuration

**CSPM (Cloud Security Posture Management)**:
- Collect security configuration data
- Enables security compliance monitoring
- Requires `resource_collection_enabled: true`
- Requires additional IAM permissions on service account

**Security Command Center Integration**:
- Collect Security Command Center findings
- Import security findings as events in Datadog
- Requires additional IAM permissions
- Requires Security Command Center to be enabled in GCP

**Resource Change Collection**:
- Track resource configuration changes over time
- Enables change tracking and audit trail
- Requires `resource_collection_enabled: true`

### Resource Collection

**Extended Resource Collection**:
- Collects comprehensive resource metadata
- Enables resource tagging and relationships
- Required for CSPM and Cloud Cost Management
- Includes:
  - Resource tags/labels
  - Resource relationships
  - Resource configurations
  - Networking information

**Per-Project Quota Attribution**:
- Apply `X-Goog-User-Project` header in API calls
- Attributes API quota to monitored project
- Useful when service account is in different project
- Ensures quota tracking accuracy

### Automute

**GCE Instance Automute**:
- Automatically mute monitors when GCE instances are stopped
- Prevents false alerts during maintenance
- Only applies to expected instance shutdowns
- Does not affect crash or failure detection

## Setup Workflows

### Complete GCP Integration Setup (V2 - Recommended)

**1. Create Datadog GCP Delegate Account**:
```bash
pup gcp delegate create
```

This returns a Datadog delegate service account email (e.g., `ddgci-xxxxx@datadog-gci-sts-us5-prod.iam.gserviceaccount.com`)

**2. Create Service Account in GCP** (Manual step in GCP Console/CLI):
```bash
# Create service account
gcloud iam service-accounts create datadog-integration \
  --display-name="Datadog Integration" \
  --project=my-gcp-project

# Grant required roles (see IAM Permissions section below)
gcloud projects add-iam-policy-binding my-gcp-project \
  --member="serviceAccount:datadog-integration@my-gcp-project.iam.gserviceaccount.com" \
  --role="roles/compute.viewer"

# Additional roles as needed...
```

**3. Configure Workload Identity** (Manual step in GCP):
```bash
# Allow Datadog delegate to impersonate your service account
gcloud iam service-accounts add-iam-policy-binding \
  datadog-integration@my-gcp-project.iam.gserviceaccount.com \
  --member="serviceAccount:DATADOG_DELEGATE_EMAIL" \
  --role="roles/iam.workloadIdentityUser" \
  --project=my-gcp-project
```

**4. Create GCP Integration in Datadog**:
```bash
pup gcp accounts create \
  --client-email="datadog-integration@my-gcp-project.iam.gserviceaccount.com" \
  --automute=true \
  --resource-collection-enabled=true \
  --is-cspm-enabled=true \
  --account-tags='["env:prod", "team:platform"]' \
  --monitored-resource-configs='[{"type":"gce_instance","filters":["env:production"]}]'
```

### Optimizing Metric Collection

**1. List Current Integration**:
```bash
pup gcp accounts list
```

**2. Disable Unused Metric Namespaces**:
```bash
pup gcp accounts update \
  <account-id> \
  --metric-namespace-configs='[
    {"id":"compute","disabled":false},
    {"id":"cloudsql","disabled":false},
    {"id":"pubsub","disabled":false},
    {"id":"aiplatform","disabled":true},
    {"id":"dataflow","disabled":true}
  ]'
```

**3. Add Resource Filters for Cost Optimization**:
```bash
# Only monitor production resources
pup gcp accounts update \
  <account-id> \
  --monitored-resource-configs='[
    {"type":"gce_instance","filters":["env:production"]},
    {"type":"cloud_run_revision","filters":["env:production"]},
    {"type":"cloud_function","filters":["env:production"]}
  ]'
```

**4. Apply Metric-Level Filters**:
```bash
# Exclude noisy regional metrics
pup gcp accounts update \
  <account-id> \
  --metric-namespace-configs='[
    {"id":"pubsub","filters":["!*_by_region","snapshot.*"]}
  ]'
```

### Multi-Project Strategy

For organizations with multiple GCP projects:

**1. Create Integration for Each Project**:
- Use consistent labeling across projects
- Apply appropriate resource filters per project
- Use descriptive account tags

**2. Example Multi-Project Setup**:
```bash
# Production project
pup gcp accounts create \
  --client-email="datadog-integration@prod-project.iam.gserviceaccount.com" \
  --account-tags='["env:prod", "team:platform"]' \
  --is-cspm-enabled=true \
  --resource-collection-enabled=true

# Staging project
pup gcp accounts create \
  --client-email="datadog-integration@staging-project.iam.gserviceaccount.com" \
  --account-tags='["env:staging", "team:platform"]' \
  --is-cspm-enabled=false \
  --monitored-resource-configs='[{"type":"gce_instance","filters":["team:backend"]}]'
```

### Migrating from V1 to V2

**1. List Existing V1 Integrations** (if using deprecated V1 API):
```bash
# Note: V1 endpoints are deprecated, this is for reference only
# Use the V2 API for all new integrations
```

**2. Set Up V2 Integration**:
Follow the complete V2 setup workflow above

**3. Verify V2 Integration is Working**:
Check metrics are flowing in Datadog UI

**4. Remove V1 Integration** (after verification):
Once V2 is confirmed working, delete the V1 integration

## Error Handling

### Common Errors and Solutions

**Missing Credentials**:
```
Error: DD_API_KEY environment variable is required
```
→ Set DD_API_KEY and DD_APP_KEY environment variables

**Invalid Service Account Email**:
```
Error: Invalid client_email format
```
→ Service account email must follow format: `name@project-id.iam.gserviceaccount.com`

**Workload Identity Not Configured**:
```
Error: Unable to authenticate with service account
```
→ Verify:
- Datadog delegate account has been created
- Service account exists in GCP project
- Workload Identity binding is configured correctly
- Service account has required IAM permissions

**Account Already Exists**:
```
Error: GCP integration already exists for this service account
```
→ Use list command to find existing integration, then use update instead

**Insufficient Permissions (Datadog)**:
```
Error: Insufficient permissions
```
→ Ensure Datadog API/App keys have `gcp_configurations_manage` or `gcp_configuration_edit` permissions

**Insufficient Permissions (GCP)**:
```
Error: Service account lacks required permissions
```
→ Verify service account has required IAM roles in GCP (see IAM Permissions section)

**CSPM Requires Resource Collection**:
```
Error: CSPM requires resource_collection_enabled
```
→ Enable resource collection when enabling CSPM:
```bash
--resource-collection-enabled=true --is-cspm-enabled=true
```

**Project Not Accessible**:
```
Error: Unable to access GCP project
```
→ Verify:
- Service account exists in the project or has cross-project access
- Required APIs are enabled in GCP project
- Workload Identity binding is correct

## Best Practices

### Security
1. **Use Workload Identity**: Always prefer STS/Workload Identity over service account keys
2. **Least Privilege IAM**: Use only required roles for your monitoring needs
3. **Enable CSPM**: Activate Cloud Security Monitoring for security visibility
4. **Monitor Service Account**: Track usage and changes to Datadog service account
5. **Tag Resources**: Apply consistent labels for better access control and cost attribution

### Cost Optimization
1. **Resource Filtering**: Use monitored resource filters to exclude dev/test resources
2. **Namespace Disabling**: Disable metric namespaces for unused GCP services
3. **Metric Filtering**: Exclude noisy metrics with filter patterns
4. **Regional Metrics**: Exclude per-region metrics if not needed (`!*_by_region`)
5. **Project Quota**: Enable per-project quota when monitoring multiple projects

### Performance
1. **Resource Type Filtering**: Only enable monitored resources you need
2. **Label Optimization**: Use efficient label filters (avoid overly broad patterns)
3. **Metric Filters**: Apply filters to reduce metric processing overhead
4. **Batch Operations**: Update multiple settings in single API call when possible

### Monitoring
1. **Integration Health**: Regularly check integration status in Datadog
2. **Metric Gaps**: Monitor for missing metrics indicating configuration issues
3. **CSPM Findings**: Review security findings regularly
4. **Resource Changes**: Track resource change events for audit trail
5. **Cost Attribution**: Use account tags for cost tracking across teams

### Maintenance
1. **Regular Audits**: Review active integrations quarterly
2. **Remove Unused**: Delete integrations for decommissioned projects
3. **Update Filters**: Adjust resource and metric filters as infrastructure evolves
4. **Security Reviews**: Periodically review IAM permissions
5. **Documentation**: Maintain runbook of GCP project to team mapping

```

**When user asks "Set up GCP integration for my production project":**
```
I'll help you set up GCP integration for your production project.

⚠️ GCP Integration Setup Process:

**Step 1: Create Datadog GCP Delegate Account**
<Execute delegate create command>

Created Datadog GCP delegate account:
`ddgci-xxxxx@datadog-gci-sts-us5-prod.iam.gserviceaccount.com`

**Step 2: Create Service Account in GCP** (You need to do this manually)

1. Create service account in your GCP project:
```bash
gcloud iam service-accounts create datadog-integration \
  --display-name="Datadog Integration" \
  --project=YOUR_PROJECT_ID
```

2. Grant required IAM roles:
```bash
# Basic monitoring
gcloud projects add-iam-policy-binding YOUR_PROJECT_ID \
  --member="serviceAccount:datadog-integration@YOUR_PROJECT_ID.iam.gserviceaccount.com" \
  --role="roles/compute.viewer"

gcloud projects add-iam-policy-binding YOUR_PROJECT_ID \
  --member="serviceAccount:datadog-integration@YOUR_PROJECT_ID.iam.gserviceaccount.com" \
  --role="roles/monitoring.viewer"

# For CSPM (optional)
gcloud projects add-iam-policy-binding YOUR_PROJECT_ID \
  --member="serviceAccount:datadog-integration@YOUR_PROJECT_ID.iam.gserviceaccount.com" \
  --role="roles/iam.securityReviewer"
```

3. Configure Workload Identity:
```bash
gcloud iam service-accounts add-iam-policy-binding \
  datadog-integration@YOUR_PROJECT_ID.iam.gserviceaccount.com \
  --member="serviceAccount:ddgci-xxxxx@datadog-gci-sts-us5-prod.iam.gserviceaccount.com" \
  --role="roles/iam.workloadIdentityUser" \
  --project=YOUR_PROJECT_ID
```

**Step 3: Create Integration in Datadog**

What features would you like to enable?
- Cloud Monitoring Metrics (GCE, GKE, Cloud SQL, etc.)
- Cloud Security Posture Management (CSPM)
- Security Command Center integration
- Resource change tracking
- Automute for GCE instances

Please provide:
- GCP Project ID: ?
- Service account email: ?
- Which features to enable: ?
```

**When user asks "Enable CSPM for my GCP project":**
```
I'll enable Cloud Security Posture Management for your GCP project.

⚠️ Prerequisites for CSPM:
1. Service account must have `roles/iam.securityReviewer` role
2. Resource collection must be enabled

Let me update your GCP integration to enable CSPM and resource collection.

<Execute update command with is-cspm-enabled and resource-collection-enabled>

✓ CSPM has been enabled for your GCP integration.

**Next steps**:
1. Verify your service account has the required IAM roles:
   - roles/compute.viewer
   - roles/iam.securityReviewer
   - roles/cloudasset.viewer

2. Security findings will start appearing in Datadog within 15-30 minutes

3. You can view findings in the Security > Cloud Security Management section

Would you like to also enable Security Command Center integration?
```

## Integration Notes

This agent works with GCP Integration APIs:

**V2 API** (Recommended - `/api/v2/integration/gcp/accounts`):
- STS-based authentication with Workload Identity
- More secure with short-lived tokens
- Comprehensive configuration options
- Includes delegate account management

**V1 API** (Deprecated - `/api/v1/integration/gcp`):
- Service account key-based authentication
- Less secure with long-lived keys
- Limited configuration options
- Being phased out

**Migration Path**: All new integrations should use V2 API. If you have V1 integrations:
- Plan migration to V2 for enhanced security
- Set up Workload Identity for keyless authentication
- V1 API will eventually be removed

**Key Differences from AWS Integration**:
- GCP uses Workload Identity instead of role-based authentication
- No separate endpoints for logs or EventBridge
- Simpler configuration model with fewer moving parts
- Metric and resource filtering configured in account settings
