WES Metrics Agent

Plugin to collect and report the system metrics.

Run Instructions

In order for the GPU information to be collected the container needs access to the hosts /sys/kernel/debug directory. Therefore, a volume mount is necessary.

Docker:

docker run --privileged --rm -it -v /sys/kernel/debug:/sys/kernel/debug --entrypoint /bin/bash joe:latest

Kubernetes Pod:

apiVersion: v1
kind: Pod
metadata:
  name: my-pod
  labels:
    app: my-app
spec:
  containers:
    - name: app
      image: localhost:5000/joe:latest
      volumeMounts:
      - mountPath: /sys/kernel/debug
        name: sys-kernel-debug
      securityContext:
        privileged: true
  volumes:
  - name: sys-kernel-debug
    hostPath:
      path: /sys/kernel/debug
      type: Directory

Notes: tegrastats

The tegrastats tool is used to collect system metrics on NVidia Tegra hardware. The following resources were used as reference to parse that data:
