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	Count of 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 (eg. `http`, `mqtt`).
device/billing_bytes_count Billable bytes transferred	GAUGE, INT64, per registry	Count of 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 (eg. `http`, `mqtt`). direction: Direction of data traffic (`ingress` or `egress`).
device/error_count Errors communicating with devices	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: Type of error. For example, 'pubsub_publish', or 'incoming_buffer_full'. protocol: Device protocol (eg. 'mqtt', 'http').
device/operation_count Operations	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: Type of operation performed.
device/received_bytes_count Bytes received from devices	DELTA, INT64, By registry	Delta count of 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 number of bytes sent to devices. Sampled every 60 seconds. After sampling, data is not visible for up to 180 seconds.
