DSE Search logging

Information about DSE Search logging.

DSE Search logs errors, warnings, debug, trace, and info messages in the system log: /var/log/cassandra/system.log.

Search logging classes

To add debug logging to a class permanently using the logback framework, use nodetool setlogginglevel to confirm the component or class before setting it in the logback.xml file in installation_location/conf. Modify to include the following line or similar at the end of the file:

<logger name="org.apache.cassandra.gms.FailureDetector" level="DEBUG"/>

Restart the node to invoke the change.

Accessing the validation log

Validation errors occur when non-indexable data is sent from nodes other than DSE Search nodes. The validation errors are logged in:

/var/log/cassandra/solrvalidation.log

For example, if a node that is not running DSE Search puts a string in a date field, an exception is logged for that column when the data is replicated to the search node.
