Grafana dashboard: Selenoid Stats
Description: Browsers and resource usage
for project https://github.com/aerokube/selenoid

Example dashboard for [Selenoid](https://github.com/aerokube/selenoid)'s [Sending Statistics to External Systems](http://aerokube.com/selenoid/latest/#_sending_statistics_to_external_systems) help section, but with **telegraf + influxdb** pair.

## Features
- Shows total usage of browsers on each host
- Can show usage of browsers in quota
- Can show browser usage in quotas
- Can match LA with active browsers

## Requirements
You should install telegraf agent on each selenoid host to make possible system metrics collection.

## Example
Example of ready-to-use **telegraf+influxdb+grafana** with docker-compose can be found at https://github.com/aerokube/selenoid-grafana-example
