This document describes how to monitor usage of your smart home Actions and how to access event logs. You can access these features from your Google Cloud Project to debug issues you may encounter.
Monitoring
You can get helpful usage metrics about your Smart home Actions through Cloud Monitoring. You can create dashboards, set up alerts, and access metrics data programmatically.
Supported metrics
Cloud Monitoring monitors the assistant_action_project resource type, and
provides the following metrics:
| Metric | Kind | Description |
|---|---|---|
smarthome_action/request_count |
DELTA |
Count of intent requests, labeled with execution_type,
status, and trait.
execution_type (String): Smart home intent type.
status (String): Result of the request.
trait (String): Smart home device trait. Events without an
associated trait include the label UnknownTrait.
|
smarthome_action/request_latencies |
CUMULATIVE, DISTRIBUTION |
Distribution of latencies for intent requests, labeled with
execution_type,
status, and trait.
execution_type (String): Smart home intent type.
status (String): Result of the request.
trait (String): Smart home device trait. Events without an
associated trait include the label UnknownTrait.
|
smarthome_action/num_active_user |
GAUGE |
Daily active users, labeled with trait.
trait (String): Smart home device trait. Events without an
associated trait include the label UnknownTrait.
|
Access metrics
To access Cloud Monitoring for your project:
In the Cloud Platform Console, go to the Projects page.
Select your smart home project.
Under Operations, select Monitoring > Metrics explorer.
Smart home dashboard
Smart home projects have access to the SmartHome Analytics dashboard, which is pre-populated with the following charts to surface metrics for cloud and local fulfillment usage:
| Metric | Cloud | Local | Overall |
|---|---|---|---|
| Total Request Count | |||
| Request Success Percentage | |||
| Execution Breakdown | |||
| Query Breakdown | |||
| 95th Percentile Latency | |||
| Daily Active Users | |||
| Mean Request Latency |
To access the smart home dashboard for your project:
In the Actions console, go to the Projects page.
Select your smart home project.
Choose the Analytics tab, and click Go to Google Cloud Platform.

Logging
You can access event logs for your smart home Actions via Cloud Logging. You can view them in the Cloud console, or export them to other applications via Google Cloud Pub/Sub.
Cloud Logging provides the following resource types:
| Resource Type | Display Name | Description | Labels |
|---|---|---|---|
assistant_action_project |
Google Assistant Action Project | A container for the Google Cloud Project associated with an Assistant Action. |
|
Smart home events
Your Actions console project supports the following events in Cloud Logging:
| Cloud Logging Resource | Event |
|---|---|
| Google Assistant Action Project | SYNC intent errors |
| QUERY intent errors | |
| EXECUTE intent errors | |
| Account linking errors | |
| Local Home SDK HandlerError |
Sync payload
The table below lists the schema of a syncLog entry:
| Property | Description |
|---|---|
requestId |
Smart home intent request ID. |
httpLatencyMsec |
Elapsed time before a response was received. |
status |
Indicates the status of the intent response. |
Execution payload
The table below lists the schema of an executionLog entry:
| Property | Description |
|---|---|
requestId |
Smart home intent request ID. |
latencyMsec |
Elapsed time before a response was received. |
executionType |
Transport used for the request, such as "Cloud" or "Local". |
actionType |
Optional indicator of the user action taken, such as "QUERY" or "EXECUTE". For EXECUTE actions, includes the command issued to fulfillment for supported traits. |
trait |
Optional trait associated with this user action. |
deviceTypes |
List of device types affected by the event. |
isSuccess |
Whether the request received a successful response. |
fallbackToCloud |
Whether the request routed to cloud fulfillment following an error from local fulfillment. |
statusType |
Indicates the status of the intent response, such as "SUCCESS",
"PENDING", or "OFFLINE". For "ERROR" responses, this property contains
the errorCode provided by the fulfillment.
|
externalDebugString |
Optional detailed debugging message associated with this user action. |
locale |
Language code associated with the request. |
Access the log
To access Cloud Logging for your project:
In the Cloud Platform console, go to the Projects page.
Select your smart home project.
Under Operations, select Logging > Logs Viewer.
Access to logging data is managed through Identity and Access Management (IAM) for users of your Actions project. For more details on roles and permissions for logging data, see Cloud Logging access control.
Log entries are retained for 30 days per the Cloud Logging retention policy, then scheduled for deletion. You can also delete entries on demand by using the Logs Viewer interface.
