# OpenTelemetry PSR-3 auto-instrumentation

Please read https://opentelemetry.io/docs/instrumentation/php/automatic/ for instructions on how to

install and configure the extension and SDK.

## Overview

Auto-instrumentation hooks are registered via composer, and depending on the mode, will:

* automatically inject trace id and span id into log message context of any psr3 logger; or

* transform the message into the OpenTelemetry LogRecord format, for export to an OpenTelemetry logging-compatible backend

## Mode

The package can operate in two modes, controlled by the environment variable `OTEL_PHP_PSR3_MODE`:

### `inject`

Inject `traceId` and `spanId` of the active trace span into the context of each logged message. Depending on the PSR-3 implementation,

the values may be written to the log output, or may be available for interpolation into the log message.

For example:

```php

putenv('OTEL_PHP_PSR3_MODE=inject');

require 'vendor/autoload.php';

$logger = /* create logger */

$logger->info('traceId={traceId} spanId={spanId}');

```

### `export`

The logged output will be processed and emitted by the logger as normal, but the output will also be encoded using

the [OpenTelemetry log model](https://opentelemetry.io/docs/specs/otel/logs/data-model/) and can be

exported to an OpenTelemetry-compatible backend.

```php

putenv('OTEL_PHP_PSR3_MODE=export');

putenv('OTEL_PHP_AUTOLOAD_ENABLED=true');

putenv('OTEL_LOGS_EXPORTER=console');

require 'vendor/autoload.php';

$logger = /* create logger */

$logger->info('Hello, OTEL');

```

## Configuration

The extension can be disabled via [runtime configuration](https://opentelemetry.io/docs/instrumentation/php/sdk/#configuration):

```shell

OTEL_PHP_DISABLED_INSTRUMENTATIONS=psr3

```
