AWS Cloud Infrastructure

Monitor and analyze AWS resources using Dynatrace Smartscape and DQL. Query AWS services, optimize costs, manage security, and plan capacity across your AWS infrastructure.

When to Use This Skill

Use this skill when the user needs to work with AWS resources in Dynatrace. Load the reference file for the task type:

• Inventory: "Show me all EC2 instances in us-east-1"
• Network: "Find all resources in VPC vpc-abc123"
• Database: "List all RDS instances with Multi-AZ enabled"
• Serverless: "Show Lambda functions with VPC access"
• Cost: "Find unattached EBS volumes for cost savings"
• Security: "Identify publicly accessible databases"
• Compliance: "Find resources missing Environment tags"
• Capacity: "Analyze subnet IP utilization"
• Troubleshoot: "Map load balancer to instances through target groups"
• Problem Analysis: "What changed before this AWS problem?" / "What events affected this resource?"
• Workload Context: "Is this instance behind a load balancer, in an EKS cluster, or managed by ECS?"
• Events: "Have there been any recent events in AWS affecting this resource?"

Core Concepts

Entity Types

AWS resources use the AWS_* prefix and can be queried using the smartscapeNodes function. All AWS entities are automatically discovered and modeled in Dynatrace Smartscape.

Compute: AWS_EC2_INSTANCE, AWS_LAMBDA_FUNCTION, AWS_ECS_CLUSTER, AWS_ECS_SERVICE, AWS_EKS_CLUSTER Networking: AWS_EC2_VPC, AWS_EC2_SUBNET, AWS_EC2_SECURITYGROUP, AWS_EC2_NATGATEWAY, AWS_EC2_VPCENDPOINT Database: AWS_RDS_DBINSTANCE, AWS_RDS_DBCLUSTER, AWS_DYNAMODB_TABLE, AWS_ELASTICACHE_CACHECLUSTER Storage: AWS_S3_BUCKET, AWS_EC2_VOLUME, AWS_EFS_FILESYSTEM Load Balancing: AWS_ELASTICLOADBALANCINGV2_LOADBALANCER, AWS_ELASTICLOADBALANCINGV2_TARGETGROUP Messaging: AWS_SQS_QUEUE, AWS_SNS_TOPIC, AWS_EVENTS_EVENTBUS, AWS_MSK_CLUSTER

Common AWS Fields

All AWS entities include:

• aws.account.id - AWS account identifier
• aws.region - AWS region (e.g., us-east-1)
• aws.resource.id - Unique resource identifier
• aws.resource.name - Resource name
• aws.arn - Amazon Resource Name
• aws.vpc.id - VPC identifier (for VPC-attached resources)
• aws.subnet.id - Subnet identifier
• aws.availability_zone - Availability zone
• aws.security_group.id - Security group IDs (array)
• tags - Resource tags (use tags[TagName])

AWS Fields on Logs and Bizevents

AWS-originated logs (fetch logs) carry these fields — no exploration needed:

• aws.region, aws.account.id, aws.service, aws.log_group, aws.log_stream
• Plus standard log fields: content, loglevel, timestamp, k8s.*, dt.smartscape.*

AWS-originated bizevents (fetch bizevents) carry:

• aws.region, aws.account.id, event.type, event.provider

Use filter isNotNull(aws.region) to scope to AWS-originated records.

Relationship Types

AWS entities use these relationship types:

• is_attached_to - Exclusive attachment (e.g., volume to instance)
• uses - Dependency relationship (e.g., instance uses security group)
• runs_on - Vertical relationship (e.g., instance runs on AZ)
• is_part_of - Composition (e.g., instance in cluster)
• belongs_to - Aggregation (e.g., service belongs to cluster)
• balances - Load balancing (e.g., target group balances instances)
• balanced_by - Inverse load-balancing relationship (e.g., load balancer balanced by target group)

AWS Metric Key Naming Convention

Dynatrace ingests AWS CloudWatch metrics using this pattern:

cloud.aws.<service>.<MetricName>.By.<DimensionName>

The <service> is the lowercase AWS service name, <MetricName> is the CloudWatch metric name (case-preserved), and <DimensionName> is the CloudWatch dimension.

Examples: cloud.aws.ec2.CPUUtilization.By.InstanceId, cloud.aws.lambda.Invocations.By.FunctionName, cloud.aws.rds.CPUUtilization.By.DBInstanceIdentifier

Use timeseries, not fetch, for these metrics. Group by dt.smartscape_source.id to split by entity.

→ See references/metrics-performance.md for the complete metric catalog by service with DQL query templates.

Key Workflows

1. AWS Resource Discovery

Get all AWS resources by type:

smartscapeNodes "AWS_*"
| summarize count = count(), by: {type}
| sort count desc

Filter by account and region:

smartscapeNodes "AWS_*"
| filter aws.account.id == "123456789012" and aws.region == "us-east-1"
| fields type, name, aws.resource.id

Using tags for filtering:

smartscapeNodes "AWS_*"
| filter tags[Environment] == "production"
| summarize count = count(), by: {type, aws.region}

→ For complete resource inventory patterns, see references/resource-management.md

2. VPC Networking Analysis

List all VPCs:

smartscapeNodes "AWS_EC2_VPC"
| fields name, aws.account.id, aws.region, aws.vpc.id

Find resources in a VPC:

smartscapeNodes "AWS_*"
| filter aws.vpc.id == "vpc-0be61db7c5d2d1bd1"
| summarize resource_count = count(), by: {type, aws.subnet.id}
| sort resource_count desc

Analyze security group usage:

smartscapeNodes "AWS_EC2_INSTANCE"

Common Query Patterns

Pattern	Template
Discovery	smartscapeNodes "AWS_*" | fieldsAdd <attrs> | filter <cond> | summarize <agg>
Config parsing	smartscapeNodes "AWS_<T>" | parse aws.object, "JSON:awsjson" | fieldsAdd f = awsjson[configuration][field]
Traversal	smartscapeNodes "AWS_<SRC>" | traverse "<rel>", "AWS_<TGT>"
Multi-type	smartscapeNodes "AWS_T1", "AWS_T2" | filter <cond> | summarize count(), by: {type}

Best Practices

Query Optimization

1. Filter early by account and region
2. Use specific entity types (avoid "AWS_*" wildcards when possible)
3. Limit results with | limit N for exploration
4. Use isNotNull() checks before accessing nested fields

Configuration Parsing

1. Always parse aws.object with JSON parser: parse aws.object, "JSON:awsjson"
2. Use consistent field naming: fieldsAdd configField = awsjson[configuration][field]
3. Check for null values after parsing
4. Use toString() for complex nested objects

Security Fields

1. Security group IDs are arrays - use contains() or expand
2. Parse aws.object for detailed security context
3. Check publiclyAccessible, storageEncrypted, and similar flags
4. Validate IAM role assumptions

Tagging Strategy

1. Use tags[TagName] for filtering by specific tag value
2. tags is a JSON object, not an array — use isNull(tags) for untagged resources, never arraySize(tags)
3. Use isNull(tags[TagName]) to find resources missing a specific tag
4. Implement consistent tag naming conventions
5. Track tag coverage with summarize operations

Limitations and Notes

Smartscape Limitations

• AWS object configuration requires parsing with parse aws.object, "JSON:awsjson"
• AWS metrics are available as Dynatrace metrics using the cloud.aws.* naming convention (see AWS Metric Naming Convention)
• Resource discovery depends on AWS integration configuration
• Tag synchronization may have slight delays

Relationship Traversal

• Use direction:backward for reverse relationships (e.g., target group → load balancer)
• Use fieldsKeep to maintain important fields through traversal
• Access traversal history with dt.traverse.history[-N]
• Complex topologies may require multiple traverse operations

General Tips

• Use getNodeName() for human-readable resource names
• Handle null values gracefully with isNotNull() and isNull()
• Combine region and account filters for large environments
• Use countDistinct() for unique resource counts
