Logging¶

Chose the desired configuration option below to see the key-value pairs and their options:

Configuration File

Keys	Values	Details	Defaults
`log_level`	`LEVEL`	where `LEVEL` is a string that represents the desired logging level. Supported levels are `all`, `debug`, `info`, `warn` and `error`.	`warn`

Environment Variables

Keys	Values	Details	Defaults
`ULTRALEAP_OPENXR_LOG_LEVEL`	`LEVEL`	where `LEVEL` is a string that represents the desired logging level. Supported levels are `all`, `debug`, `info`, `warn` and `error`.	`warn`

What does it do?¶

By default the layer will output error and warnings generated during the usage of an OpenXR application.

How to use it¶

Set the logging to the desired verbosity level shown above and when an OpenXR application runs that makes use of one of our supported extensions logs will be output to the following platform specific locations:

Windows: %PROGRAMDATA%\Ultraleap\OpenXR\UltraleapOpenXR.log
Linux: $XDG_STATE_HOME/ultraleap/openxr-layer-ultraleap.log
Android: The log is written directly to logcat.

Note

Currently the log file is not circular buffered. So if you have a very verbose logging level set, the file will grow very quickly in size; requiring manual clean-up. This doesn’t apply for Android.
