Reference documentation and code samples for the Stackdriver Logging Client class LoggingClient.
Google Stackdriver Logging allows you to store, search, analyze, monitor, and alert on log data and events from Google Cloud Platform and Amazon Web Services. Find more information at the Google Stackdriver Logging docs .
This client supports transport over REST or gRPC.
In order to enable gRPC support please make sure to install and enable the gRPC extension through PECL:
$ pecl install grpc
NOTE: Support for gRPC is currently at an Alpha quality level, meaning it is still a work in progress and is more likely to get backwards-incompatible updates.
When using gRPC in production environments, it is highly recommended that you make use of the Protobuf PHP extension for improved performance. Protobuf can be installed via PECL .
$ pecl install protobuf
Example:
use Google\Cloud\Logging\LoggingClient;
$logging = new LoggingClient();
