InfluxDbPresetBundle: send metrics to InfluxDB server based on Events

Since it relies on the great official influxdb-php library client (via the Symfony bundle) you can configure the latter to benefit from:

  • Send multiple metrics at once (batch sending)
  • Udp Events (sends the metrics using UDP)
  • Http Events (sends the metrics to the InfluxDB API over HTTP)

Both methods (Udp/Http) can also be deferred, meaning you can send the metrics only when kernel.terminate event is fired in order not to slow your application. You can read more on the documentation of influxdb-bundle

profiler_influx

This bundle is inspired from StatsdBundle

Installation

Require yproximite/influxdb-preset-bundle to your composer.json file:

$ composer require yproximite/influxdb-preset-bundle

Register the bundle in app/AppKernel.php:

// app/AppKernel.php
public function registerBundles()
{
    return array(
        // ...
        new Yproximite\Bundle\InfluxDbPresetBundle\YproximiteInfluxDbPresetBundle(),
        new Yproximite\InfluxDbBundle\InfluxDbBundle(),
    );
}

Also, be sure that you followed the configuration procedure for influxdb-bundle since it uses it to take the pre-configured service to communicate with the InfluxDB server.

Configuration

Here is the configuration reference:

# app/config/config.yml
yproximite_influx_db_preset:
    default_profile_name: default # by default it's "default"
    profiles:
        default:

Usage

Sending

through events:

use Yproximite\Bundle\InfluxDbPresetBundle\Event\InfluxDbEvent;

// Symfony\Component\EventDispatcher\EventDispatcherInterface
$eventDispatcher = $this->get('event_dispatcher');

// Preset from default profile
$eventDispatcher->dispatch('app.user.created', new InfluxDbEvent(1));

// Advanced event parameters
$event = new InfluxDbEvent(
    $value = 1, // will be converted to float
    string $profileName = 'other',
    ?\DateTimeInterface $dateTime = new \DateTime()
);

$eventDispatcher->dispatch('app.order.requested', $event);

using the client:

// Yproximite\Bundle\InfluxDbPresetBundle\Client\ClientInterface
$client = $this->get('yproximite.influx_db_preset.client.client');

$client->sendPoint(
    string $profileName = 'other',
    string $presetName = 'app.user.created',
    float $value = 0.5,
    ?\DateTimeInterface $dateTime = new \DateTime()
);

Listening for events

you can listen each client request through ClientRequestEvent:

use Yproximite\Bundle\InfluxDbPresetBundle\Event\ClientRequestEvent;

final class MyAppListener
{
    public function onClientRequest(ClientRequestEvent $event)
    {
        dump(
            $event->getProfileName(),
            $event->getPresetName(),
            $event->getValue(),
            $event->getDateTime()
        );
    }
}

do not forget to add the following code into services.yml:

services:
    app.event_listener.my_app_listener:
        class: AppBundle\EventListener\MyAppListener
        tags:
            - { name: kernel.event_listener, event: yproximite.bundle.influx_db_preset.client_request, method: onClientRequest }

You can enable extensions that will automatically (see configuration example) send the metrics for the memory usage, how much time the Request/Response cycle last, the status code of errors and the quantity of page views.
