During run-time, Aerial components can be re-configured or queried for status via gRPC remote procedure calls (RPCs).  The RPCs are defined in “protocol buffers” syntax, allowing support for clients written in any of the languages supported by gRPC and protocol buffers.

More information about gRPC may be found at: https://grpc.io/docs/what-is-grpc/core-concepts/

More information about protocol buffers may be found at: https://developers.google.com/protocol-buffers

Simple Request/Reply Flow

Feature Status: MFL

Aerial applications support a request/reply flow using the gRPC framework with protobufs messages.  At run-time, certain configuration items may be updated and certain status information may be queried.  An external OAM client interfaces with the Aerial application acting as the gRPC server.

image14.png


Streaming Request/Replies

Feature Status: MFL

Aerial applications support the gRPC streaming feature for sending (a)periodic status between client and server.

image15.png


Asynchronous Interthread Communication

Feature Status: MFL

Certain request/reply scenarios require interaction with the high-priority CPU-pinned threads orchestrating GPU work.  These interactions occur through Aerial-internal asynchronous queues, and requests are processed on a best effort basis which prioritizes the orchestration of GPU kernel launches and other L1 tasks.

rpc GetCpuUtilization

Feature Status: MFL

The GetCpuUtilization returns a variable-length array of CPU utilization per-high-priority-core.

CPU utilization is available through the Prometheus node exporter, however the design approach used by Aerial high-priority threads results in a false 100% CPU core utilization per thread. This RPC allows retrieval of the actual CPU utilization of high-priority threads. High-priority threads are pinned to specific CPU cores.

rpc GetFAPIStream

Feature Status: MFL

This RPC requests snooping of one or more (up to infinite number) of SCF FAPI messages.  The snooped messages are delivered from the Aerial gRPC server to a third party client.  See cuPHY-CP/cuphyoam/examples/aerial_get_l2msgs.py for an example client.

rpc TerminateCuphycontroller

Feature Status: MFL

This RPC message terminates cuPHYController with immediate effect

rpc CellParamUpdateRequest

Feature Status: MFL

This RPC message updates cell configuration without stopping the cell. Message specification:

Copy
Copied!

Setting the log level to LOG_NONE means no logs will be sent to the shared memory logger.

The OAM Metrics API is used internally by cuPHY-CP components to report metrics (counters, gauges, and histograms).  The metrics are exposed via a Prometheus Aerial exporter.

Host Metrics

Feature Status: MFL

Host metrics are provided via the Prometheus node exporter. The node exporter provides many thousands of metrics about the host hardware and OS, such as but not limited to

  • CPU statistics

  • Disk statistics

  • Filesystem statistics

  • Memory statistics

  • Network statistics

Please refer to https://github.com/prometheus/node_exporter and https://prometheus.io/docs/guides/node-exporter/ for detailed documentation on the node exporter.

GPU Metrics

Feature Status: MFL

GPU hardware metrics are provided through the GPU Operator via the Prometheus dcgm exporter. The dcgm exporter provides many thousands of metrics about the GPU and PCIe bus connection, such as but not limited to

  • GPU hardware clock rates

  • GPU hardware temperatures

  • GPU hardware power consumption

  • GPU memory utilization

  • GPU hardware errors including ECC

  • PCIe throughput

Please refer to https://github.com/NVIDIA/gpu-operator for details on the GPU operator.

Please refer to https://github.com/NVIDIA/gpu-monitoring-tools for detailed documentation on the dcgm exporter.

An example grafana dashboard is available at https://grafana.com/grafana/dashboards/12239

Aerial Metric Naming Conventions

Feature Status: MFL

In addition to metrics available through the node exporter and dcgm exporter, Aerial exposes several application metrics.

Metric names are per https://prometheus.io/docs/practices/naming/ and will follow the format aerial_<component>_<sub-component>_<metric description>_<units>

Metric types are per https://prometheus.io/docs/concepts/metric_types/

The component and sub-component definitions are in the table below:

Co mponent

Su b-Component

Description

cuphycp cuPHY Control Plane application
fapi L2/L1 interface metrics
cplane Fronthaul C-plane metrics
uplane Fronthaul U-plane metrics

pbch Physical Broadcast Channel metrics
pdsch Physical Downlink Shared Channel metrics
pdcch Physical Downlink Common Channel metrics
