Perfbase for Yii 3

Yii 3 integration for Perfbase.

This package is a thin adapter over perfbase/php-sdk. It keeps the framework layer thin and pushes transport, extension access, and submission behavior into the shared SDK.

Scope

v1 supports:

• HTTP profiling through PSR-15 middleware
• Console command profiling through Symfony Console events

v1 does not support:

• Queue or worker profiling
• Scheduler-specific profiling
• Custom buffering or retries
• Yii-specific profiler UI

Requirements

• PHP >=8.1 <8.5
• yiisoft/yii-http ^1.1
• yiisoft/yii-console ^2.4
• perfbase/php-sdk ^1.0
• The Perfbase PHP extension installed for the target PHP runtime

Installation

composer require perfbase/yii3

Add the config provider:

return [
    \Perfbase\Yii3\ConfigProvider::class,
];

Then override params as needed:

return [
    'perfbase' => [
        'enabled' => true,
        'api_key' => $_ENV['PERFBASE_API_KEY'] ?? '',
        'sample_rate' => 0.1,
        'app_version' => '1.0.0',
    ],
];

Configuration

The config provider exposes this default config under params['perfbase']:

[
    'enabled' => false,
    'debug' => false,
    'log_errors' => true,
    'api_key' => '',
    'api_url' => 'https://ingress.perfbase.cloud',
    'sample_rate' => 0.1,
    'timeout' => 10,
    'proxy' => null,
    'flags' => \Perfbase\SDK\FeatureFlags::DefaultFlags,
    'app_version' => '',
    'include' => [
        'http' => ['*'],
        'console' => ['*'],
    ],
    'exclude' => [
        'http' => [],
        'console' => [],
    ],
]

Notes:

• sample_rate must be numeric between 0.0 and 1.0
• environment comes from YII_ENV, otherwise production
• app_version is application-defined

HTTP Integration

HTTP profiling is middleware-based through PerfbaseHttpMiddleware.php.

Register it in your HTTP middleware pipeline:

use Perfbase\Yii3\Middleware\PerfbaseHttpMiddleware;

return [
    PerfbaseHttpMiddleware::class,
    // other middleware...
];

Behavior:

• starts profiling before delegating to the next handler
• captures response status on success
• captures exception context on failure
• always stops profiling in finally

HTTP attributes include:

• source=http
• action
• http_method
• http_url
• http_status_code
• user_ip
• user_agent
• hostname
• environment
• app_version
• php_version

Route metadata behavior:

• route template is resolved from request attributes such as routePattern, route, or _route
• route name is resolved from routeName or route_name
• controller metadata is resolved from controller or action
• http_url excludes query strings

Console Integration

Console profiling is wired through ConsoleProfilerSubscriber.php, which subscribes to Symfony Console events used by Yii3 console packages.

Register the subscriber with your event dispatcher:

use Perfbase\Yii3\EventSubscriber\ConsoleProfilerSubscriber;
use Symfony\Component\EventDispatcher\EventDispatcher;

$dispatcher = $container->get(EventDispatcher::class);
$dispatcher->addSubscriber($container->get(ConsoleProfilerSubscriber::class));

Subscribed events:

• ConsoleEvents::COMMAND
• ConsoleEvents::ERROR
• ConsoleEvents::TERMINATE

Behavior:

• lifecycles are keyed by the input object identity
• exceptions are attached on ERROR
• exit codes are attached on TERMINATE
• lifecycle state is cleaned up even when command execution fails

Filters

Supported contexts:

• http
• console

Supported filter styles:

• *
• .*
• glob patterns such as cache/*
• regex patterns such as /^GET \/api\//

Example:

'perfbase' => [
    'include' => [
        'http' => ['route/*', '/^GET \\/api\\//'],
        'console' => ['cache/*', 'migrate'],
    ],
    'exclude' => [
        'http' => ['debug/*'],
        'console' => ['help'],
    ],
],

Error Handling

The adapter is fail-open:

• SDK init failures degrade to a no-op
• missing extension degrades to a no-op
• submit failures do not break request or command execution

Behavior:

• debug=false: swallow and optionally log errors
• debug=true: rethrow adapter/runtime errors

Runtime Architecture

Primary entry points:

• ConfigProvider.php
• PerfbaseHttpMiddleware.php
• ConsoleProfilerSubscriber.php
• lifecycle classes in src/Lifecycle
• support helpers in src/Support

The adapter does not implement its own delivery layer.

Local Development

Local development uses the sibling SDK checkout:

{
  "repositories": [
    {
      "type": "path",
      "url": "../lib-php-sdk"
    }
  ]
}

Verify locally with:

composer install
composer run test
composer run phpstan

Limitations

• No queue support in v1
• No scheduler-specific integration in v1
• No Yii-specific debug toolbar integration
• HTTP and console wiring must be registered explicitly in the host application
