Scout Laravel APM Agent

Monitor the performance of PHP Laravel applications with Scout's PHP APM Agent. Detailed performance metrics and transaction traces are collected once the scout-apm package is installed and configured.

Any of the constants defined in \Psr\Log\LogLevel are acceptable values for this configuration option.

In order for Scout APM Error Handling to pick up uncaught exceptions, you should add the appropriate Scout APM call, for example:

• Registers a service \Scoutapm\ScoutApmAgent::class into the container (useful for dependency injection)
• Provides a Facade \Scoutapm\Laravel\Facades\ScoutApm
• Wraps view engines to monitor view rendering times
• Injects several middleware for monitoring controllers and sending statistics to the Scout Core Agent
• Adds a listener to the database connection to instrument SQL queries

Custom Instrumentation

In order to perform custom instrumentation, you can wrap your code in a call to the instrument method. For example, given some code to be monitored:

Using the provided Facade for Laravel, you can wrap the call and it will be monitored.
