Dynatrace OpenKit logging

There are two different ways to log with OpenKit:

Configure OpenKit to use the built-in console logger
Configure OpenKit to use a custom logger implementation

Logging via console logger

OpenKit includes a console logger. By default, any error or warning message is logged to stdout. When you set a log level, all log events with the same or higher prior levels are logged.

OpenKit uses the following log levels:

Log level	Priority	Description
Debug	0	For debugging and development. Not recommended for production due to a high volume of log entries.
Info	10	General OpenKit flow.
Warning	20	Warnings encountered in OpenKit library, including API usage problems.
Error	30	Errors that cannot be handled by OpenKit.

1OpenKit openKit = new DynatraceOpenKitBuilder(endpointURL, applicationID, deviceID)
2    .withLogLevel(LogLevel.DEBUG) // enable Debug, Info, Warning, and Error log events
3    .build();

Logging via custom logger

You can also configure OpenKit with a custom logger implementation. Implement a custom logger to log OpenKit messages using the logging framework of your choice.

10    .withLogger(customLogger)
11    .build();
