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.

Synopsis

nodetool [<connection_options>] setlogginglevel
[--] <component> | <class> <level>
Syntax legend
Syntax conventions Description

Italic, bold, or < >

Syntax diagrams and code samples use one or more of these styles to mark placeholders for variable values. Replace placeholders with a valid option or your own user-defined value.

In CQL statements, angle brackets are required to enclose data types in a set, list, map, or tuple. Separate the data types with a comma. For example: <datatype2

In Search CQL statements, angle brackets are used to identify the entity and literal value to overwrite the XML element in the schema and solrconfig files, such as @<xml_entity>='<xml_entity_type>'.

[ ]

Square brackets surround optional command arguments. Do not type the square brackets.

( )

Parentheses identify a group to choose from. Do not type the parentheses.

|

A pipe separates alternative elements. Type any one of the elements. Do not type the pipe.

...

Indicates that you can repeat the syntax element as often as required.

'

Single quotation marks must surround literal strings in CQL statements. Use single quotation marks to preserve upper case. + For Search CQL only: Single quotation marks surround an entire XML schema declaration, such as '<<schema> ... </schema>>'

{ }

Map collection. Curly braces enclose maps ({ <key_datatype>:<value_datatype> }) or key value pairs ({ <key>:<value> }). A colon separates the key and the value.

;

Ends a CQL statement.

--

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

Options

If an option has a short and long form, both forms are given, separated by a comma.

-h, --host hostname

The hostname or IP address of a remote node or nodes. When omitted, the default is the local machine.

-p, --port jmx_port

The JMX port number.

-pw, --password jmxpassword

The JMX password for authenticating with secure JMX. If a password is not provided, you are prompted to enter one.

-pwf, --password-file jmx_password_filepath

The filepath to the file that stores JMX authentication credentials.

-u, --username jmx_username

The username for authenticating with secure JMX.

class

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

level

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 the following:

  • ALL: Log all levels

  • TRACE: Very detailed log messages. Output is recorded to the debug.log only.

  • DEBUG: Less detailed than TRACE, but more detailed than INFO. Output is recorded to the debug.log only.

  • INFO (default): At this level, debug.log is disabled. Includes general operational entries, warnings, and errors.

  • WARN: Minimal detail. Only reports warnings and errors.

  • ERROR: Least detailed logs. Only reports errors.

  • OFF: No logging.

More verbose log levels (ALL, TRACE, DEBUG, and potentially INFO) can generate heavy logging output on a moderately trafficked cluster.

Examples

Set the logging level for the StorageProxy service to TRACE:

nodetool setlogginglevel org.apache.cassandra.service.StorageProxy TRACE

Log all messages for the CQL service:

nodetool setlogginglevel cql ALL
