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:

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:

export DREMIO_ADMIN_LOG_VERBOSITY=<value>
