View events in the DSE audit log table

The dse_audit.audit_log table for DataStax Enterprise (DSE) stores database activity events for all nodes that have auditing enabled with the CassandraAuditWriter logger. Use CQL to query the table and view results.

Set the replication factor for the dse_audit keyspace to at least one in all datacenters where auditing is enabled.

audit_log columns

The audit log table contains all events from nodes that have auditing enabled. DSE parses the events into the following columns.

In cqlsh, use DESC TABLE dse_audit.audit_log to view table schema. The table has a compound partition key, date, node, day_partition, and a single clustering column event time.
