Cloud ClearBlade IoT Core exports usage metrics that can be monitored programmatically or accessed via Cloud Monitoring. These metrics are aggregated at the registry level. You can use Cloud Monitoring to create dashboards or set up alerts.

Viewing metrics

Go to Cloud Monitoring in the Google Cloud console to view Monitoring dashboards or define Monitoring alerts. You can also use query and view device registry metrics using the Cloud Monitoring API to query and view metrics for device registries.

Metrics that will be created by IoT Core and be monitored for each registry individually:

Name and label	Kind, type, unit	Description
device/active_devices Active devices	GAUGE, INT64, 1	The number of devices that have recently sent data to ClearBlade IoT Core. Sampled every 60 seconds. After sampling, data is not visible for up to 180 seconds. protocol: Device protocol (e.g., `http`, `mqtt`).
device/billing_bytes_count Billable bytes transferred	GAUGE, INT64,  per registry	The number of billable bytes transferred by devices. Sampled every 60 seconds. After sampling, data is not visible for up to 180 seconds. protocol: Device protocol (e.g., `http`, `mqtt`). direction: Data traffic direction (`ingress` or `egress`).
device/error_count Errors communicating with devices device/error_count.error	DELTA, INT64, 1	Delta count of errors communicating with devices, grouped by error type. Sampled every 60 seconds. After sampling, data is not visible for up to 180 seconds. error: Error type, possible options: telemetry_publish_internal telemetry_publish_user set_state_internal set_state_user incoming_buffer_full _internal - Number of events failed because of an internal error. _user - Number of events failed because of invalid request, permission denied, or no quota. protocol: Device protocol (e.g., mqtt, http).
device/operation_count Operations device/operation_count.operation_type	DELTA, INT64, 1	Delta count of operations performed, grouped by operation type. Sampled every 60 seconds. After sampling, data is not visible for up to 180 seconds. operation_type: Operation type performed, possible options: event state heartbeat subscribe unsubscribe config_sent config_ack command_sent command_ack connection_open disconnect
device/received_bytes_count Bytes received from devices	DELTA, INT64,  By registry	Delta count of the number of bytes received from devices. Sampled every 60 seconds. After sampling, data is not visible for up to 180 seconds.
device/sent_bytes_count Bytes sent to devices	DELTA, INT64,  By registry	Delta count of the number of bytes sent to devices. Sampled every 60 seconds. After sampling, data is not visible for up to 180 seconds.
