Run the PHP Example

The PHP example generates random example metrics. The random metrics are beeing sent via UDP to the telegraf agent using the StatsD protocol.

The telegraf agents aggregates the incoming data and perodically persists the data into the InfluxDB database.

Grafana connects to the InfluxDB database and is able to visualize the incoming data.

$ cd php-example
$ composer install
$ php example.php
