# Speedtest.net Collector For InfluxDB and Grafana
|
||||
|
||||
|
||||
|
||||
This tool is a wrapper for speedtest-cli which allows you to run periodic speedtets and save the results to Influxdb
|
||||
|
||||
## TL;DR;
|
||||
|
||||
```console
|
||||
$ helm repo add billimek https://raw.githubusercontent.com/billimek/helm-repo/master
|
||||
$ helm install billimek/speedtest
|
||||
```
|
||||
|
||||
## Installing the Chart
|
||||
|
||||
To install the chart with the release name `my-release`:
|
||||
|
||||
```console
|
||||
$ helm install --name my-release billimek/speedtest
|
||||
```
|
||||
|
||||
## Uninstalling the Chart
|
||||
|
||||
To uninstall/delete the `my-release` deployment:
|
||||
|
||||
```console
|
||||
$ helm delete my-release --purge
|
||||
```
|
||||
|
||||
The command removes all the Kubernetes components associated with the chart and deletes the release.
|
||||
|
||||
## Configuration
|
||||
|
||||
The configuration is set as a block of text through a configmap and mouted as a file in /src/config.ini Any value in this text block should match the defined speedtest configuration. There are several values here that will have to match our kubernetes configuration.
|
||||
|
||||
## Configuration
|
||||
|
||||
The following tables lists the configurable parameters of the Sentry chart and their default values.
|
||||
|
||||
| Parameter | Description | Default |
|
||||
| ------------------------------- | ------------------------------- | ---------------------------------------------------------- |
|
||||
| `image.repository` | speedtest image | `billimek/speedtestusage-for-influxdb` |
|
||||
| `image.tag` | speedtest image tag | `latest` |
|
||||
| `image.pullPolicy` | speedtest image pull policy | `IfNotPresent` |
|
||||
| `debug` | Display debugging output | `false` |
|
||||
| `config.delay` | how many seconds to wait between checks | `3600` |
|
||||
| `config.influxdb.host` | InfluxDB hostname | `influxdb-influxdb` |
|
||||
| `config.influxdb.port` | InfluxDB port | `8086` |
|
||||
| `config.influxdb.database` | InfluxDB database | `speedtests` |
|
||||
| `config.influxdb.username` | InfluxDB username | `` |
|
||||
| `config.influxdb.password` | InfluxDB password | `` |
|
||||
| `config.influxdb.ssl` | InfluxDB connection using SSL | `false` |
|
||||
| `config.speedtest.server` | server to use for speedtest - leave blank to auto-pick | `` |
|
||||
|
||||
Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
|
||||
|
||||
```console
|
||||
$ helm install --name my-release \
|
||||
--set config.influxdb.host=some-influx-host \
|
||||
billimek/speedtest
|
||||
```
|
||||
|
||||
Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
|
||||
|
||||
```console
|
||||
$ helm install --name my-release -f values.yaml billimek/speedtest
|
||||
```
|
||||
|
||||
Read through the [values.yaml](values.yaml) file. It has several commented out suggested values.

|

You can connect to the container running speedtest. To open a shell session in the pod run the following:
|
||||
|
||||
- kubectl exec -i -t --namespace {{ .Release.Namespace }} $(kubectl get pods --namespace {{ .Release.Namespace }} -l app={{ template "speedtest.fullname" . }} -o jsonpath='{.items[0].metadata.name}') /bin/sh
|
||||
|
||||
To trail the logs for the speedtest pod run the following:
|
||||
|
||||
- kubectl logs -f --namespace {{ .Release.Namespace }} $(kubectl get pods --namespace {{ .Release.Namespace }} -l app={{ template "speedtest.fullname" . }} -o jsonpath='{ .items[0].metadata.name }')
