AWS Neuron

The AWS Neuron source collects metrics from AWS Neuron devices, the accelerators on AWS Inferentia2, Trainium, and Trainium2 instances, using the OpenTelemetry awsneuronreceiver. It gathers NeuronCore utilization and FLOPS, execution counts, errors, and latency, per-runtime and per-device memory usage, and ECC error counts. Optional metrics add device power, per-core inference and status counters, per-runtime vCPU utilization, and system CPU and memory usage. Metrics come from the Neuron driver's sysfs tree and, when available, the neuron-monitor binary.

The receiver collects only on Linux. It depends on the Neuron kernel driver's sysfs tree and the neuron-monitor binary, both of which are Linux only.

Prerequisites

  • A Linux host with AWS Neuron devices and the Neuron kernel driver installed. The driver provides the sysfs tree (/sys/devices/virtual/neuron_device) and the /dev/neuron* devices. The sysfs files are world-readable, so no special capability or group grant is needed.

  • For the full metric set, the neuron-monitor binary, shipped in the aws-neuronx-tools package. It is not bundled with the collector and must be installed separately. If it is absent, the receiver still runs on the sysfs-only path with a reduced metric set; it does not crash.

  • A Bindplane collector that includes awsneuronreceiver v1.8.0+.

  • Performance metrics require an active workload. Per-runtime metrics (utilization, FLOPS, execution counts, latency, errors, and per-model memory) are produced by the Neuron runtime only while a process is actively executing a model. On an idle host these are empty; ECC, topology, and host and device memory still report.

Supported hardware: AWS Inferentia2 (inf2), Trainium (trn1), and Trainium2 (trn2). First-generation Inferentia (inf1) is not officially validated but appears to function, with two known limitations: it emits no power telemetry (aws.neuron.device.power.utilization is never produced) and its ECC error counters are always zero.

Configuration

Bindplane docs - AWS Neuron - image 1

The Metrics selector groups the available metrics into the categories below. Each metric is an independent toggle. The Default column shows whether it is collected unless you change it. Performance and runtime-gated metrics report only while a workload is running (see Prerequisites).

Parameter
Type
Required
Default
Description

Neuron Monitor Command1

String

Yes

neuron-monitor

Path to, or name of, the neuron-monitor binary, resolved against PATH.

Collection Interval

Integer

No

60

How often (seconds) to scrape for metrics.

1 The neuron-monitor binary is provided by the aws-neuronx-tools package. If it is missing, the receiver logs a single error and continues on the sysfs-only path with a reduced metric set.

Examples

Collect at a finer interval with a custom neuron-monitor path

This configuration scrapes every 30 seconds and points at a neuron-monitor binary installed outside the default PATH. The default metric set is collected; use the Metrics selector in the UI to enable opt-in metrics or disable default ones.

Configuration Tips

  • The collection interval also drives the neuron-monitor subprocess period, so the two stay in lockstep. Do not set the interval below 10 seconds; many backends cannot ingest faster, and an interval shorter than the monitor period re-emits the same report as duplicate points.

  • The device power metric refreshes only about once a minute on the device, so intervals below 60 seconds re-read the same power value.

  • aws.neuron.device.power.utilization reports the device's power draw as a fraction of its maximum power, emitted as min, max, and avg statistics per period. It tracks load but it is not NeuronCore compute utilization. It is emitted only when the sysfs power status is VALID, and never on first-generation Inferentia (inf1). See the Neuron Sysfs User Guide for the underlying per-minute power statistics this metric is derived from.

  • The receiver also stamps cloud.* and host.* resource attributes (plus aws.neuron.device.type and aws.neuron.neuroncore.version) when neuron-monitor is active. These overlap with the Resource Detection processor; by default detection wins, so no action is needed.

Troubleshooting

No performance metrics are collected

Symptoms: NeuronCore utilization, FLOPS, execution counts, latency, and per-runtime memory are empty, while ECC and memory metrics still report.

Solutions:

  1. Confirm a workload is actively executing a model on the device. The Neuron runtime produces per-runtime performance metrics only while a model is running.

  2. Confirm neuron-monitor is installed and on the collector's PATH. Most performance metrics come from neuron-monitor, not sysfs.

A reduced metric set is reported

Symptoms: only the sysfs-sourced metrics appear, and the collector log shows a single neuron-monitor error.

Solutions:

  1. Install the aws-neuronx-tools package, which provides neuron-monitor.

  2. Set the Neuron Monitor Command to the correct binary path if it is not on PATH.

The device power metric is never emitted

Symptoms: aws.neuron.device.power.utilization produces no data points even though it is enabled.

Solutions:

  1. Confirm the sysfs power status is VALID. Idle or unsupported power states emit nothing.

  2. Confirm the hardware is not first-generation Inferentia (inf1), which has no power telemetry.

A scrape error is logged every interval

Symptoms: the collector logs a scrape error on every collection cycle.

Solutions:

  1. This occurs only when both the neuron-monitor and sysfs collection paths fail. Confirm the Neuron driver is installed (sysfs tree present) and neuron-monitor is reachable. Losing a single path logs one error and continues on the other; losing both produces a per-scrape error.
