Log Directory

The default value for DREMIO_ADMIN_LOG_DIR is null (not set). When this parameter is not set, log files are not created.

To set the log directory, provide the log directory path by running the following:

Set log directory

export DREMIO_ADMIN_LOG_DIR=<path>

note

The export option must be set and access must be available for the user running the dremio-admin command.

Log Verbosity

Log verbosity is used in conjunction with DREMIO_ADMIN_LOG_DIR. Otherwise, all the output is printed to stdout; there is no control on setting verbosity for stdout.

Verbosity options include:

• TRACE
• DEBUG
• INFO (default)
• WARN
• ERROR

To set the log verbosity (default: INFO), provide the verbose level by running the following:

Set log verbosity

export DREMIO_ADMIN_LOG_VERBOSITY=<value>
