Configuring auditing for a DSE Search cluster 

The filter-mapping element in the Solr web.xml file enables auditing.

If auditing is enabled, DSE Search nodes do not require additional configuration. If the filter-mapping element in the Solr web.xml file is commented out, the auditor cannot log anything from Solr.

Procedure

If necessary, uncomment the filter-mapping element in the Solr web.xml file.
The default location of the web.xml file depends on the type of installation:
Installer-Services and Package installations /usr/share/dse/solr/web/solr/WEB-INF/web.xml
Installer-No Services and Tarball installations install_location/resources/solr/web/solr/WEB-INF/web.xml
<filter-mapping>
    <filter-name>DseAuditLoggingFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

Here is an example of the data audit log of a Solr query:
