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.

Syntax conventions Description


Literal keyword.


Not literal.


Variable value. Replace with a valid option or user-defined value.

[ ]

Optional. Square brackets ( [ ] ) surround optional command arguments. Do not type the square brackets.

( )

Or. A vertical bar ( | ) separates alternative elements. Type any one of the elements. Do not type the vertical bar.


Repeatable. An ellipsis ( ... ) indicates that you can repeat the syntax element as often as required.

'<Literal string>'

Single quotation ( ' ) marks must surround literal strings in CQL statements. Use single quotation marks to preserve upper case.

{ <key>:<value> }

Map collection. Braces ( { } ) enclose map collections or key value pairs. A colon separates the key and the value.

End CQL statement. A semicolon ( ; ) terminates all CQL statements.

[ -- ]

Separate the command line options from the command arguments with two hyphens ( -- ). This syntax is useful when arguments might be mistaken for command line options.

The following values are valid for the log class qualifier:

  • org.apache.cassandra

  • org.apache.cassandra.db

  • org.apache.cassandra.service.StorageProxy

component: The following values are valid for the log components qualifier:

  • bootstrap

  • compaction

  • cql

  • repair

  • ring

  • streaming


If class qualifier and level arguments to the command are empty or null, logging levels are reset to the initial configuration.

The valid values for setting the log level include ALL for logging information at all levels, TRACE through ERROR, and OFF for no logging. TRACE creates the most verbose log, and ERROR, the least.

  • ALL



  • INFO (Default)

  • WARN


  • OFF
