# Logging levels

Avaya one-X Agent offers four different types of logging levels. These four levels of logging are applicable to the oneXAgent.log files. To enable logging level for Avaya one-X Agent, on the top bar, click System Options > System settings and select Event Logging.

Agents can use the following logging levels to view or record log files:

Name | Description
--- | ---
DEBUG | The DEBUG level logging designates fine-grained informational events that are most useful to debug the application. The DEBUG log level provides a detailed view of the function call and return stack. If enabled, Avaya one-X Agent records debug messages. Important Avaya does not recommend enabling the DEBUG level logging as there is a possible potential performance issues relating to the workstation especially when under-load of other applications, except for troubleshooting a specific issue that are not apparent in the INFO level logs.
INFO | The INFO level logging includes certain executed code points and informational messages that highlight the progress of the application at coarse-grained level. If enabled, Avaya one-X Agent records debug and informational messages. Note Avaya recommends INFO level logging to be turned on in production environments.
WARNING | The WARNING level logging includes warnings that indicate possible problems, but the execution continues. If enabled, Avaya one-X Agent records debug, informational, and warning messages.
ERROR | The ERROR level logging includes application errors that prevent a function from completing normally. If enabled, Avaya one-X Agent records debug, informational, warning, and error messages.

Important

By default, the SPARK Emulator logging is disabled. Any level of logging can effect the performance and perhaps even message sequences of the emulator. Avaya recommends closing all other application running on the personal computer if the SPARK Emulator logging is enabled.
