Amazon CloudWatch metrics - AWS Private 5G

Amazon CloudWatch metrics

You can monitor AWS Private 5G using CloudWatch, which collects raw data and processes it into readable, near real-time metrics. These statistics are kept for 15 months, so that you can access historical information and gain a better perspective on how your web application or service is performing. You can also set alarms that watch for certain thresholds, and send notifications or take actions when those thresholds are met. For more information, see the Amazon CloudWatch User Guide.

You can track metrics at the network-level and radio-unit level.

NetworkStatusCheckFailed

Reports whether the network has passed the status check in the last minute. This metric can be either 0, which means passed, or 1, which means failed. This metric aggregates the status of the radio unit with health statistics from the core.

AccessPointStatusCheckFailed

Reports whether the radio unit has passed the status check in the last minute. This metric can be either 0, meaning connected, or 1, meaning either disconnected or Spectrum Access System (SAS) is unavailable.

Unit: Count

ChannelGrantStatus

Reports the grant status of the radio unit. A radio unit can have one of the following grant statuses:

  • RadioUnitGrantStatusGranted: The grant is authorized by the SAS.

  • RadioUnitGrantStatusNotGranted: The grant is not authorized by the SAS and is denied.

  • RadioUnitGrantStatusTransmitting: The grant is successfully allocated and the radio unit is active and transmitting.

  • RadioUnitGrantStatusSuspended: The grant is suspended by the SAS because of unexpected behavior from the radio unit such as:

    • The radio unit fails to maintain a connection with the SAS.

    • The radio unit exceeds the authorized dBm or bandwidth limits.

    • A user with either incumbent or priority access starts transmitting in the same frequency in the same area (geographical location).

  • RadioUnitGrantStatusTerminated: The grant is terminated by the SAS because of an Environmental Sensing Capability (ECS) event.

Unit: Count

Maximum resolution: 5 minutes

Dimensions: RadioUnitSerialNumber

RadioUnitUplinkThroughput

Uplink throughput in MB for a radio unit. The maximum uplink throughput for a radio unit is 20 MBps. This metric provides the following information:

  • RadioUnitUplinkThroughputUsagePercent: The percent throughput utilization. Use this value to determine how much capacity is still available.

  • RadioUnitUplinkThroughput: The uplink throughput.

Unit: Megabytes/Second

Maximum resolution: 5 minutes

Dimensions: RadioUnitSerialNumber

RadioUnitDownlinkThroughput

Downlink throughput in MB for a radio unit. The maximum downlink throughput for a radio unit is 200 MBps. This metric provides the following information:

  • RadioUnitDownlinkThroughputUsagePercent: The percent throughput utilization. Use this value to determine how much capacity is still available.

  • RadioUnitDownlinkThroughput: The downlink throughput.

Unit: Megabytes/Second

Maximum resolution: 5 minutes

Dimensions: RadioUnitSerialNumber

RadioUnitStatus

Reports the status of the radio unit. A radio unit can have one of the following statuses:

  • RadioUnitStatusProvisioning: The radio unit is being configured by AWS.

  • RadioUnitStatusReady: The radio unit is ready to receive the channel grant from the SAS.

  • RadioUnitStatusInService: The radio unit is active and transmitting.

  • RadioUnitStatusOutOfService: The radio unit is inactive or might be powered off.

Unit: Hour:Second

Maximum resolution: 5 minutes

Dimensions: RadioUnitSerialNumber

RadioUnitNumberOfActiveUserDevices

Number of transmitting, active user equipments connected to the network. Each radio unit can have a maximum of 64 concurrently transmitting, active user equipments.

Unit: Count

Maximum resolution: 1 minute

Dimensions: RadioUnitSerialNumber

RadioUnitNumberOfActiveUserDevicesPercent

Percentage of transmitting, active user equipments connected to the network. Each radio unit can have a maximum of 64 concurrently transmitting, active user equipments. This metric shows the percentage of connected devices based on the 64 maximum limit.

Unit: Percent

Maximum resolution: 1 minute

Dimensions: RadioUnitSerialNumber

To filter these metrics, use the following dimensions.
