Metrics

The Symfony bundle comes with an integration for the Metrics component that allows you to easily collect and publish metrics.

Collectors

You can create metric collectors using YAML. The available types, at the moment, are the following:

  • :rabbitmq: will get some metrics about a RabbitMq queue, from the management API.

The following YAML is a reference of the possible configuration.

tolerance:
    metrics:
        collectors:
            my_queue:
                type: rabbitmq
                namespace: metric.prefix
                options:
                    host: %rabbitmq_host%
                    port: %rabbitmq_management_port%
                    username: %rabbitmq_user%
                    password: %rabbitmq_password%
                    vhost: %rabbitmq_vhost%
                    queue: %rabbitmq_queue_name%

Publishers

You can create publishers using YAML. The available types, at the moment, are the following:

  • :hosted_graphite: publish some metrics to the HostedGraphite service.
  • :beberlei: publish some metrics using a "collector" from beberlei/metrics.

The following YAML is a reference of the possible configuration.

tolerance:
    metrics:
        publishers:
            hosted_graphite:
                type: hosted_graphite
                options:
                    server: %hosted_graphite_server%
                    port: %hosted_graphite_port%
                    api_key: %hosted_graphite_api_key%

            statsd:
                type: beberlei
                options:
                    service: beberlei_metrics.collector.statsd
                    auto_flush: true

Your own consumer and publishers

If you want to register your own consumers and publishers to the default collection services, you have to tag your services with the :tolerance.metrics.collector and :tolerance.metrics.publisher tags.

Command

A command to collect and publish the metrics is built-in in the Bundle. As an example, you can run this command periodically to be able to graph metrics from your application.

app/console tolerance:metrics:collect-and-publish

If required, you can configure the collector and publisher used by this command:

tolerance:
    metrics:
        command:
            collector: tolerance.metrics.collector.collection
            publisher: tolerance.metrics.publisher.collection

Request

If configured, the bundle will register listeners to send two metrics (a timing and an increment) at the end of each request.

In other words, you just have to put this YAML configuration in order to publish metrics about the duration and the number of requests to your Symfony application:

tolerance:
    metrics:
        request:
            namespace: my_api.http.request
            publisher: tolerance.metrics.publisher.statsd
