Solr log messages
DSE Search logs Solr errors, warnings, debug, trace, and info messages in the Cassandra system log.
DSE Search logs Solr errors, warnings, debug, trace, and info messages in the
Cassandra system log:
/var/log/cassandra/system.log
Changing the Solr logging level
You can control the granularity of Solr log messages, and other log messages, in the Cassandra system.log file by configuring the logback.xml file.
The location of the
logback.xml file depends on the type of
installation:
Installer-Services and Package installations | /etc/dse/cassandra/logback.xml |
Installer-No Services and Tarball installations | install_location/resources/cassandra/logback.xml |
To set log levels, specify one of these values:
- All - turn on all logging
- OFF - no logging
- FATAL - severe errors causing premature termination
- ERROR - other runtime errors or unexpected conditions
- WARN - use of deprecated APIs, poor use of API, near errors, and other undesirable or unexpected runtime situations
- DEBUG - detailed information on the flow through the system
- TRACE - more detailed than DEBUG
- INFO - highlight the progress of the application at a coarse-grained level
Accessing the validation log
DSE Search stores validation errors that arise from non-indexable data that is sent from nodes
other than DSE Search
nodes:
/var/log/cassandra/solrvalidation.log
For example, if a Cassandra 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 Solr node.
