Fos HTTP Cache show as index.php

[Webonaute]

I have problem to see my cached request to display in new relic. they all show as index.php

is there a way to specially name it cached_\?

[Nyholm]

Sure. Have a look at the NamingStrategy section. https://github.com/ekino/EkinoNewRelicBundle#transaction-naming-strategies

but why my cache is see as index.php instead of routename?

here is my config. did I miss anything?

ekino_new_relic:
    enabled: true                         # Defaults to true
    application_name: 'api-%kernel.environment%' # default value in newrelic is "PHP Application", or whatever is set
                                          # as php ini-value
    deployment_names: '%api_version%'                   # default value is 'application_name', supports string array or semi-colon separated string
    api_key:  '%newrelic_api_key%'        # New Relic API
    license_key: '%newrelic_license_key%' # New Relic license key (optional, default value is read from php.ini)
    xmit: false                           # if you want to record the metric data up to the point newrelic_set_appname is called, set this to true (default: false)
    logging: false                        # If true, logs all New Relic interactions to the Symfony log (default: false)
    #interactor: Ekino\NewRelicBundle\NewRelic\AdaptiveInteractor                      # The interactor service that is used. Setting enabled=false will override this value
    twig: false                           # Allows you to disable twig integration (falls back to class_exists(\Twig_Environment::class))
    exceptions: true                      # If true, sends exceptions to New Relic (default: true)
    deprecations: false                   # If true, reports deprecations to New Relic (default: true)
    instrument: false                     # If true, uses enhanced New Relic RUM instrumentation (see below) (default: false)
    http:
        enabled: true
        using_symfony_cache: true        # Symfony HTTP cache (see below) (default: false)
        transaction_naming: route         # route, controller or service (see below)
    #    transaction_naming_service: ~     # Transaction naming service (see below)
    #    ignored_routes: []                # No transaction recorded for this routes
    #    ignored_paths: []                 # No transaction recorded for this paths
    #monolog:
    #    enabled: false                    # When enabled, send application's logs to New Relic (default: disabled)
    #    channels: [app]                   # Channels to listen (default: null). [See Symfony's documentation](http://symfony.com/doc/current/logging/channels_handlers.html#yaml-specification)
    #    level: error                      # Report only logs higher than this level (see \Psr\Log\LogLevel) (default: error)
    #    service: app.my_custom_handler    # Define a custom log handler (default: ekino.new_relic.monolog_handler)
    commands:
        enabled: true                     # If true, logs CLI commands to New Relic as Background jobs (>2.3 only) (default: true)
        ignored_commands: []              # No transaction recorded for this commands (background tasks)

from what I see, the RequestListener is never trigger on cached request. so the transaction name cannot be set.

[jderusse]

Hmm.. are you using SymfonyCache?

If yes, Symfony is probably returning the cached response before calling the NewrelicBundle's code. That would explain why the transaction is not defined.

[Webonaute]

Yeah. That’s what I found. I am using FoshttpCache bundle. Look like I need a special subscriber in my AppCache setup.

[jderusse]

Thinking about your issue, IMHO, this is a good thing that the RequestListener is not called. First, for performance reason, but mainly because NewRelic should not mix metrics from cached response with not-cached.

I think you may try to set a ReverseCache temporary name in the Kernel's handle function. This name will be overrided by the RequestListener for Missed calls, and it'll stay a default name for Cached responses.

class CacheKernel extends HttpCache
{
  public function handle(Request $request, $type = HttpKernelInterface::MASTER_REQUEST, $catch = true) {
    newrelic_name_transaction('cached');
    // or with NR objects: (new AdaptiveInteractor(new NewRelicInteractor(), new BlackholeInteractor))->setTransactionName('cached');

    return parent::handle($request, $type, $catch);
  }
}

Could you give a try and tell us if it works for you? We'll add an entry in the documentation

[Webonaute]

already try to handle the transaction name in the handle method, it's not applied.
