adaptant/edgetpu-exporter repository overview

⁠EdgeTPU Prometheus Exporter

This is a Prometheus Exporter for EdgeTPU metrics.

⁠Building and Installing

Building and installing is the same as for other Go projects:

$ go get github.com/adaptant-labs/edgetpu-exporter

⁠Usage

edgetpu-exporter can be run as-is without any additional configuration.

$ edgetpu-exporter --help
EdgeTPU Prometheus Exporter
Usage: edgetpu-exporter [flags]

  -port int
    	Port to listen to (default 8080)
  -sysfs string
    	Mountpoint of sysfs instance to scan (default "/sys")

By default, it will listen on port 8080, but this can be changed via the -port argument.

⁠Metrics

The following metrics are exported:

Note that not all Apex device types will support temperature checks, there is presently no mechanism by which to obtain a temperature reading from USB-attached devices.

Viewed from the exporter:

# HELP edgetpu_num_devices Number of EdgeTPU devices
# TYPE edgetpu_num_devices gauge
edgetpu_num_devices 1
# HELP edgetpu_temperature_celsius EdgeTPU device temperature in Celsius
# TYPE edgetpu_temperature_celsius gauge
edgetpu_temperature_celsius{name="apex_0"} 49.3

⁠Docker Images

Multi-arch Docker images are available on Docker Hub at adaptant/edgetpu-exporter⁠.

⁠Deployment via Kubernetes

edgetpu-exporter can be installed directly as a DaemonSet on matching nodes:

$ kubectl apply -f https://raw.githubusercontent.com/adaptant-labs/edgetpu-exporter/edgetpu-daemonset.yaml

The node selection criteria depends on the existence of node labels designating the existence of an EdgeTPU within the node. The list of node labels and their respective labelling sources are listed below:
