Caution

You're viewing documentation for a previous version. Switch to the latest stable version.

Nodetool setlogginglevel¶

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

Note

Using trace or debug logging levels will create very large log files where the readers 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 ScyllaDB 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 verbosity:

  • trace

  • debug

  • info - default setting

  • warn

  • error

Log Classes¶

To display the log classes (output changes with each version so your display may be different).

Note

Please note that this list could be outdated, so you might need to run the following command to see the updated list of logger classes.
