# Nodetool setlogginglevel¶

setlogginglevel sets the level log threashold for a given component or class during runtime. If this command is called with no parameters the log level is reset to the initial congiguration.

Note

using trace or debug logging levels create very large log files where the reader may not find what they are looking for. It is best to use these levels for a very short period of time or with the help of Scylla Support.

nodetool setlogginglevel <class> <level>


Where class is the specific class you want a log for and level is one of the below levels.

Example

This example sets the logging level of the paging class to trace:

nodetool setlogginglevel paging trace


## Log Levels¶

You can set the log to any of the following log threshold levels presented here in order of severity and verbocity:

• trace
• debug
• info - default setting
• warn
• error
