This is a Prometheus Exporter for EdgeTPU metrics.
Building and installing is the same as for other Go projects:
$ go get github.com/adaptant-labs/edgetpu-exporter
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.
The following metrics are exported:
| Metric | Description |
|---|---|
| edgetpu_num_devices | Number of EdgeTPU devices |
| edgetpu_temperature_celsius | EdgeTPU device temperature in Celsius (per device) |
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
Multi-arch Docker images are available on Docker Hub at adaptant/edgetpu-exporter.
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:
| Node Label | Labelling Source | Supported Devices |
|---|---|---|
| kkohtaka.org/edgetpu | EdgeTPU Device Plugin | USB |
| feature.node.kubernetes.io/usb-fe_1a6e_089a.present | node-feature-discovery | USB |
| feature.node.kubernetes.io/pci-0880_1ac1.present | node-feature-discovery | PCIe, Coral Dev Board |
| beta.devicetree.org/fsl-imx8mq-phanbell | k8s-dt-node-labeller | Coral Dev Board |
