Introduction
Welcome to the documentation for the DataDog SDK, which provides an easy-to-use interface for integrating your applications with the DataDog platform. This SDK allows you to send metrics, traces, and logs to DataDog, enabling you to gain valuable insights into your application’s performance and behavior.
Installation
To install the DataDog SDK, simply follow these steps:
- Open your terminal or command prompt.
- Navigate to the root directory of your project.
- Execute the following command:
“`bash
composer require datadog/datadog-php
“`
If you prefer using the package manager, you can also add the above line to your project’s composer.json file and run `composer install`.
Configuration
Before you can start using the DataDog SDK, you need to configure it with your DataDog API key. Here’s how you can do it:
- Open your project’s configuration file.
- Locate the section where you define your API credentials.
- Add the following line to set the API key:
“`php
DataDog\DogStatsD::configure(‘YOUR_API_KEY’);
“`
Replace `’YOUR_API_KEY’` with your actual API key obtained from your DataDog account. Make sure to keep your API key secure and avoid committing it to public repositories.
Usage
Once you have the DataDog SDK installed and configured, you can start using its features to send metrics, traces, and logs. Here are some examples:
Sending Metrics
To send a metric value to DataDog, use the following code:
“`php
DataDog\DogStatsD::increment(‘your_metric_name’, 1, [‘tag1’, ‘tag2’]);
“`
Replace `’your_metric_name’` with a descriptive name for your metric, and `1` with the value you want to send. Optionally, you can include an array of tags as the third argument to provide additional context or categorization for the metric.
Sending Traces
If you want to send traces to DataDog, you can use the following code snippet:
“`php
$tracer = new DataDog\Tracing\Tracer();
$span = $tracer->startSpan(‘your_operation_name’);
$span->finish();
“`
Replace `’your_operation_name’` with an appropriate name for your operation or request. The `startSpan` method initializes a new span, and `finish` marks the span as completed.
Sending Logs
To send logs to DataDog, you can use the following code snippet:
“`php
$log = new DataDog\Logger();
$log->info(‘Your log message’, [‘optional’, ‘log’, ‘tags’]);
“`
Replace `’Your log message’` with your specific log message, and `[‘optional’, ‘log’, ‘tags’]` with an array of optional tags to provide additional metadata for your log entries.
