nodetool setlogginglevel

Sets the logging level threshold for a given component or class. To see the current logging level, use nodetool getlogginglevels.

Use this command to set logging levels for services instead of modifying logback-text.xml.

Extended logging for compaction is supported and requires table configuration. The extended compaction logs are stored in a separate file.
