If using Redis, we recommend running a local Redis instance next to your PHP workers. How does it work? ----------------- [](#how-does-it-work) Usually PHP worker processes don't share any state. You can pick from four adapters. Redis, APC, APCng, or an in-memory adapter. While the first needs a separate binary running, the second and third just need the [APC](https://pecl.php.net/package/APCU) extension to be installed. If you don't need persistent metrics between requests (e.g. a long running cron job or script) the in-memory adapter might be suitable to use. Installation ------------ [](#installation) Add as [Composer](https://getcomposer.org/) dependency: ``` composer require promphp/prometheus_client_php ``` Usage ----- [](#usage) A simple counter: ``` \Prometheus\CollectorRegistry::getDefault() ->getOrRegisterCounter('', 'some_quick_counter', 'just a quick measurement') ->inc(); ``` Write some enhanced metrics: ``` $registry = \Prometheus\CollectorRegistry::getDefault(); $counter = $registry->getOrRegisterCounter('test', 'some_counter', 'it increases', ['type']); $counter->incBy(3, ['blue']); $gauge = $registry->getOrRegisterGauge('test', 'some_gauge', 'it sets', ['type']); $gauge->set(2.5, ['blue']); $histogram = $registry->getOrRegisterHistogram('test', 'some_histogram', 'it observes', ['type'], [0.1, 1, 2, 3.5, 4, 5, 6, 7, 8, 9]); $histogram->observe(3.5, ['blue']); $summary = $registry->getOrRegisterSummary('test', 'some_summary', 'it observes a sliding window', ['type'], 84600, [0.01, 0.05, 0.5, 0.95, 0.99]); $histogram->observe(5, ['blue']); ``` Manually register and retrieve metrics (these steps are combined in the `getOrRegister...` methods): ``` $registry = \Prometheus\CollectorRegistry::getDefault(); $counterA = $registry->registerCounter('test', 'some_counter', 'it increases', ['type']); $counterA->incBy(3, ['blue']); // once a metric is registered, it can be retrieved using e.g. getCounter: $counterB = $registry->getCounter('test', 'some_counter') $counterB->incBy(2, ['red']); ``` Expose the metrics: ``` $registry = \Prometheus\CollectorRegistry::getDefault(); $renderer = new RenderTextFormat(); $result = $renderer->render($registry->getMetricFamilySamples()); header('Content-type: ' . RenderTextFormat::MIME_TYPE); echo $result; ``` Change the Redis options (the example shows the defaults): ``` \Prometheus\Storage\Redis::setDefaultOptions( [ 'host' => '127.0.0.1', 'port' => 6379, 'password' => null, 'timeout' => 0.1, // in seconds 'read_timeout' => '10', // in seconds 'persistent_connections' => false ] ); ``` Using the InMemory storage: ``` $registry = new CollectorRegistry(new InMemory()); $counter = $registry->registerCounter('test', 'some_counter', 'it increases', ['type']); $counter->incBy(3, ['blue']); $renderer = new RenderTextFormat(); $result = $renderer->render($registry->getMetricFamilySamples()); ``` Using the APC or APCng storage: ``` $registry = new CollectorRegistry(new APCng()); or $registry = new CollectorRegistry(new APC()); ``` (see the `README.APCng.md` file for more details) ### Advanced Usage [](#advanced-usage) #### Advanced Histogram Usage [](#advanced-histogram-usage) On passing an empty array for the bucket parameter on instantiation, a set of default buckets will be used instead. Whilst this is a good base for a typical web application, there is named constructor to assist in the generation of exponential / geometric buckets. Eg: ``` Histogram::exponentialBuckets(0.05, 1.5, 10); ``` This will start your buckets with a value of 0.05, grow them by a factor of 1.5 per bucket across a set of 10 buckets. Also look at the [examples](examples). #### PushGateway Support [](#pushgateway-support) As of Version 2.0.0 this library doesn't support the Prometheus PushGateway anymore because we want to have this package as small als possible. If you need Prometheus PushGateway support, you could use the companion library: [https://github.com/PromPHP/prometheus\_push\_gateway\_php](https://github.com/PromPHP/prometheus_push_gateway_php) ``` composer require promphp/prometheus_push_gateway_php ``` Development ----------- [](#development) ### Dependencies [](#dependencies) - PHP ^7.2 - PHP Redis extension - PHP APCu extension - [Composer](https://getcomposer.org/doc/00-intro.md#installation-linux-unix-osx) - Redis Start a Redis instance: ``` docker-compose up Redis ``` Run the tests: ``` composer install # when Redis is not listening on localhost: # export REDIS_HOST=192.168.59.100 ./vendor/bin/phpunit ``` Black box testing ----------------- [](#black-box-testing) Just start the nginx, fpm & Redis setup with docker-compose: ``` docker-compose up ``` Pick the adapter you want to test. ``` docker-compose run phpunit env ADAPTER=apc vendor/bin/phpunit tests/Test/ docker-compose run phpunit env ADAPTER=apcng vendor/bin/phpunit tests/Test/ docker-compose run phpunit env ADAPTER=redis vendor/bin/phpunit tests/Test/ ``` Performance testing ------------------- [](#performance-testing) This currently tests the APC and APCng adapters head-to-head and reports if the APCng adapter is slower for any actions. ``` phpunit vendor/bin/phpunit tests/Test/ --group Performance ``` The test can also be run inside a container. ``` docker-compose up docker-compose run phpunit vendor/bin/phpunit tests/Test/ --group Performance ``` ### Health Score 34 — LowBetter than 77% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity9 Limited adoption so far Community19 Small or concentrated contributor base Maturity79 Established project with proven stability Bus Factor2 2 contributors hold 50%+ of commits How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
