Warning: Leaving this tool running in the background will consume a good amount of data. By default, this runs every 15 minutes, and each test can consume anywhere between 80MB and 1GB (downloads / uploads combined).
Performs periodic internet speedtests, logs the results and presents and visualises everything in a dashboard.
The Grafana dashboard is accessible without authentication, and is readonly.
Data is stored in an InfluxDB 2 time-series database, and presented using a dashboard on Grafana 8.
Under the hood, speedtest-cli is used to run the actual speedtests against the Ookla Speedtest network.
The following containers are started up:
| Name | Image | Depends on | Custom build | Purpose |
|---|---|---|---|---|
influxdb |
influxdb:2.0-alpine |
- | No | Time-series database to store the actual speed test records. |
grafana |
grafana/grafana:latest |
influxdb |
No | Graphing and visualisation tool, reading from the InfluxDB. |
speedtest-cli |
alpine:latest |
influxdb |
Yes, hence why docker-compose build is required as part of the setup steps below. |
Inclusion of speedtest-cli, as well as a daemon that periodically runs the test and ships the results to influxdb. |
Any AMD64, ARM64 ARM architecture running Docker, should support this tool.
Tested on the following setups:
- Intel Core i5 running Ubuntu 21.04 + Docker v20.10.7
- Raspberry Pi 4 running Ubuntu 20.04 + Docker v20.10.7
- Clone this project:
git clone https://github.com/francocm/speedtest-log.git - Run:
cd speedtest-log - Optional: Modify parameters inside .env.
- Optional: Modify any parameters inside docker-compose.yml.
- Run:
docker-compose build - Run:
docker-compose up -d
Then visit http://localhost:3000/d/_rotihm7k/speedtest (takes you straight to the General / Speedtest dashboard).
DO NOT delete the contents inside influx/ after the first run, or you will lose all the data collected so far!
Standard docker-compose management commands are used to manage and monitor the running containers.
The default configuration should suffice. Passwords / tokens are static and probably for the purpose of this tool, do not need to change. However, should you wish to change them, you would need to do so in a number of places. This would be described accordingly below.
All modifiable params are under .env.
| Key | Description | Avoid changing |
|---|---|---|
DOCKER_INFLUXDB_INIT_USERNAME |
The Influx DB username. This needs to match with the datasource configuration inside Grafana. | Avoid |
DOCKER_INFLUXDB_INIT_PASSWORD |
The Influx DB password. | Avoid |
DOCKER_INFLUXDB_INIT_ORG |
The Influx DB organisation. This needs to match with the datasource configuration inside Grafana. | Avoid |
DOCKER_INFLUXDB_INIT_BUCKET |
The Influx DB bucket. This needs to match with the dashboard queries. | Avoid |
DOCKER_INFLUXDB_INIT_RETENTION |
The Influx DB retention period. | Avoid |
DOCKER_INFLUXDB_INIT_MODE |
The influx DB initialisation mode. This should not be modified. | Avoid |
DOCKER_INFLUXDB_INIT_ADMIN_TOKEN |
The Influx DB token. This needs to match with the datasource configuration inside Grafana. | Avoid |
SPEEDTEST_INTERVAL_MINUTES |
The interval, in minutes, between each speedtest run. | Can modify |
SPEEDTEST_SERVER |
Optional: If set, this would contain the speedtest server ID to test against. If you have speedtest-cli, you can use speedtest-cli --list to export a list of server IDs available to you. |
Can modify |
To back-up, simply take a snapshot of the influx/ directory. Make sure you don't lose structure or permissions of individual files when doing so.
A recommended way would be:
tar czvf /path/to/backup/location/speedtest-log_backup-yyyymmdd.tar.gz influx/- The
speedtest-cliimage, is not monitoring for anySIGINTduring container shutdown, causingdocker-composeto wait too much and then getting killed forcefully after the timeout. - All passwords / tokens used in the setup above to be autogenerated during first initialisation, to avoid having shared credentials.
- Add support to LibreSpeed servers, which would enable use within internal and self-hosted environments as well.
