speedtest-go-exporter

Based on https://github.com/showwin/speedtest-go

Exported Metrics

• speedtest_upload_mbps GAUGE Speedtest upload measurement in megabits per second
• speedtest_download_mbps GAUGE Speedtest download measurement in megabits per second
• speedtest_ping_latency_ms GAUGE Speedtest ping measurement in ms
• speedtest_duration_ms GAUGE Speedtest duration in ms
• speedtest_test_errors COUNTER How many times invalid test results have been encountered (this will correlate to gaps in the data)
• speedtest_test_timeouts COUNTER how many times the speedtest exceeded the timeout (default 2 minutes; see -t option)

Usage

./speedtest-exporter exporter --help
Runs the exporter

Usage:
  speedtest-exporter exporter [flags]

Flags:
  -h, --help             help for exporter
  -p, --path string      Metrics path to listen on (default "/metrics")
  -P, --port int         Port to listen for metrics on (default 8080)
  -t, --timeoutSec int   Timeout in seconds for each speedtest. Tests exceeding this timeout will be terminated with no results recorded. (default 120)

Execute on the Commandline

Kubernetes

Note: This example uses the latest tag of quay.io/lisa/speedtest-exporter. Some users may wish to pin to a specific version, which can be done by browsing the available tags at quay.io. Additionally, the following Kubernetes YAML files can be found in /manifests, and used as the basis of more complex uses of the exporter.

Create a Deployment:

  progressDeadlineSeconds: 600
  replicas: 1
  selector:
    matchLabels:
      app: speedtest-exporter

Create a Service:

apiVersion: v1
kind: Service
metadata:
  labels:
    app: speedtest-exporter
  name: speedtest-exporter
spec:
  ports:
  - name: metrics

  type: ClusterIP

Prometheus

If using prometheus-operator, create a ServiceMonitor, perhaps tailoring for your own prometheus-operator installation which may restrict namespaces, or require other work to consume this ServiceMonitor. Configure Prometheus to use a scrape timeout that matches the exporter's timeout (default 120 seconds, specified at runtime with speedtest-exporter exporter -t <timeout>).

Graphing with Grafana or similar tools will require setting the "query options" minimum interval to match the Prometheus scrape interval.

apiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
metadata:
  labels:
    app: speedtest-exporter
  name: speedtest-exporter
spec:
  endpoints:
  - interval: 10m
    port: metrics
    scrapeTimeout: 2m
  jobLabel: speedtest-exporter
  selector:
    matchLabels:
      app: speedtest-exporter

Development

Clone the repository and compile:

git clone https://github.com/lisa/speedtest-go-exporter.git
cd speedtest-go-exporter
make build

Run the resulting speedtest-exporter binary, refer to above Usage.

Container Images

The Makefile will build for arm64 and amd64 Linux targets and tag for quay.io/lisa/speedtest-exporter using today's date as the version/tag with revision 1 (ex 2022.02.1).

To build separate container images for amd64, arm64 and s390x tagged docker.io/thedoh/speedtest-exporter:1.0.5:

make ARCHES="amd64 arm64 s390x" REGISTRY="docker.io" IMG="thedoh/speedtest-exporter" REVISION=5 VERSION=1.0 docker-build

These individual images can be "bundled" with an image manifest:

make ARCHES="amd64 arm64 s390x" REGISTRY="docker.io" IMG="thedoh/speedtest-exporter" REVISION=5 VERSION=1.0 docker-build docker-multiarch

Pushed to the registry:

make ARCHES="amd64 arm64 s390x" REGISTRY="docker.io" IMG="thedoh/speedtest-exporter" REVISION=5 VERSION=1.0 docker-build docker-multiarch docker-push

Note that there is not currently support for individually pushing the arch-specific images (though they are pushed in the docker-multiarch make target).

Roadmap

Refer to the ROADMAP.md for details.
