Core Concepts

Entity Types

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

Compute: GCP_COMPUTE_GOOGLEAPIS_COM_INSTANCE, GCP_COMPUTE_GOOGLEAPIS_COM_ADDRESS Networking: GCP_COMPUTE_GOOGLEAPIS_COM_NETWORK, GCP_COMPUTE_GOOGLEAPIS_COM_SUBNETWORK, GCP_COMPUTE_GOOGLEAPIS_COM_ROUTE, GCP_DNS_GOOGLEAPIS_COM_RESOURCERECORDSET Kubernetes (GKE): GCP_K8S_IO_POD, GCP_K8S_IO_NODE, GCP_K8S_IO_SERVICE, GCP_K8S_IO_SERVICEACCOUNT, GCP_K8S_IO_PERSISTENTVOLUMECLAIM, GCP_APPS_K8S_IO_DEPLOYMENT, GCP_APPS_K8S_IO_STATEFULSET, GCP_CONTAINER_GOOGLEAPIS_COM_NODEPOOL, GCP_RBAC_AUTHORIZATION_K8S_IO_CLUSTERROLEBINDING, GCP_RBAC_AUTHORIZATION_K8S_IO_ROLEBINDING Serverless: GCP_RUN_GOOGLEAPIS_COM_SERVICE, GCP_RUN_GOOGLEAPIS_COM_REVISION, GCP_RUN_GOOGLEAPIS_COM_EXECUTION IAM & Security: GCP_IAM_GOOGLEAPIS_COM_SERVICEACCOUNT, GCP_IAM_GOOGLEAPIS_COM_ROLE, GCP_SECRETMANAGER_GOOGLEAPIS_COM_SECRETVERSION Messaging: GCP_PUBSUB_GOOGLEAPIS_COM_TOPIC Monitoring: GCP_MONITORING_GOOGLEAPIS_COM_DASHBOARD, GCP_LOGGING_GOOGLEAPIS_COM_SAVEDQUERY Infrastructure: GCP_REGION

Common GCP Fields

All GCP entities include:

• gcp.project.id — GCP project identifier
• gcp.region — GCP region (e.g., us-central1)
• gcp.zone — GCP zone (e.g., us-central1-a)
• gcp.organization.id — GCP organization identifier
• gcp.resource.name — Resource name
• gcp.resource.type — Resource type identifier
• gcp.asset.type — GCP asset type
• gcp.object — JSON blob containing full resource configuration

GCP Organizational Hierarchy

GCP resources are organized in a hierarchy:

• Organization — Top-level container (gcp.organization.id)
• Folder — Logical grouping within an organization
• Project — Resource container (gcp.project.id)
• Region/Zone — Physical location (gcp.region, gcp.zone)

Entity Naming Convention

GCP entity types follow the pattern GCP_<SERVICE_API>_<RESOURCE>:

• Service API maps to the Google API domain (e.g., compute.googleapis.com → COMPUTE_GOOGLEAPIS_COM)
• Resource is the specific resource type (e.g., INSTANCE, NETWORK)

Examples:

• GCP_COMPUTE_GOOGLEAPIS_COM_INSTANCE — Compute Engine VM
• GCP_K8S_IO_POD — GKE pod
• GCP_RUN_GOOGLEAPIS_COM_SERVICE — Cloud Run service

Query Patterns

All GCP queries build on four core patterns. Master these and adapt them to any entity type.

Pattern 1: Resource Discovery

List resources by type, filter by project/region/zone, summarize counts:

smartscapeNodes "GCP_COMPUTE_GOOGLEAPIS_COM_INSTANCE"
| fields name, gcp.project.id, gcp.region, gcp.zone, gcp.resource.name

To list all GCP resource types, replace with "GCP_*" and add | summarize count = count(), by: {type} | sort count desc. Add filters like | filter gcp.project.id == "<PROJECT_ID>" or | filter gcp.region == "<REGION>" to scope results.

Pattern 2: Configuration Parsing

Parse gcp.object JSON for detailed configuration fields:

smartscapeNodes "GCP_COMPUTE_GOOGLEAPIS_COM_INSTANCE"
| parse gcp.object, "JSON:gcpjson"
| fieldsAdd machineType = gcpjson[configuration][resource][machineType],
            status = gcpjson[configuration][resource][status]
| fields name, gcp.project.id, machineType, status

GCP configuration fields are nested under gcpjson[configuration][resource][...] for primary resource attributes and gcpjson[configuration][additionalAttributes][...] for extended properties.

Pattern 3: Relationship Traversal

Follow relationships between resources:

smartscapeNodes "GCP_COMPUTE_GOOGLEAPIS_COM_INSTANCE"
| traverse "*", "GCP_COMPUTE_GOOGLEAPIS_COM_SUBNETWORK"
| fields name, gcp.project.id

GCP entities use "*" as the relationship name in traversals because GCP entities do not have named relationship types. Use fieldsKeep to carry fields through traversals and dt.traverse.history[-N] to access ancestor fields.

Pattern 4: Label-Based Ownership

Group resources by GCP labels for ownership and organizational tracking:

smartscapeNodes "GCP_*"
| filter isNotNull(`tags:gcp_labels`)
| fields name, gcp.project.id, `tags:gcp_labels`

GCP labels are exposed via the tags:gcp_labels field and must be accessed using backtick syntax. Replace "GCP_*" with a specific type to scope to one service.

Best Practices

Configuration Parsing

1. Always parse gcp.object with JSON parser: parse gcp.object, "JSON:gcpjson"
2. Access primary resource attributes via gcpjson[configuration][resource][...]
3. Access extended properties via gcpjson[configuration][additionalAttributes][...]
4. Check for null values after parsing with isNotNull()

GCP Hierarchy

1. Organization → Folder → Project → Region/Zone
2. Use gcp.project.id as the primary scoping filter
3. Use gcp.organization.id for cross-project queries
4. Use gcp.region and gcp.zone for location-based analysis

Entity Naming

1. Entity types follow the GCP_<SERVICE_API>_<RESOURCE> format
2. Service API maps to the Google API domain with underscores replacing dots and hyphens
3. Use specific entity types (avoid "GCP_*" wildcards when possible)

Labels

1. GCP labels must be accessed via backtick syntax: `tags:gcp_labels`
2. Use isNotNull(tags:gcp_labels) for label-based filtering
3. Track label coverage with summarize operations

Relationship Traversal

1. Use "*" as the relationship name — GCP entities do not have named relationship types
2. Use fieldsKeep to maintain important fields through traversal
3. Access traversal history with dt.traverse.history[-N]
4. Complex topologies may require multiple traverse operations

Limitations and Notes

Smartscape Limitations

• Smartscape data reflects the most recent scan; there may be a delay between GCP changes and Dynatrace visibility
• Not all GCP services are represented as entity types
• Some configuration fields may be null depending on resource setup
• Resource discovery depends on GCP integration configuration

GCP-Specific Notes

• GCP labels must be accessed via backtick syntax: `tags:gcp_labels`
• GCP entities use "*" for relationship traversal (no named relationship types)
• GCP object configuration requires parsing with parse gcp.object, "JSON:gcpjson"
• Configuration fields nest under gcpjson[configuration][resource][...] (differs from AWS pattern)

General Tips

• Filter early by project and region for better performance
• Use isNotNull() and isNull() for graceful null handling
• Combine project and region filters for large environments
• Use countDistinct() for unique resource counts
• Limit results with | limit N during exploration
