Toggle request tracing for subsequent CQL statements.

Syntax

TRACING ON
TRACING OFF
TRACING

Usage

cqlsh> TRACING ON
Now tracing requests.

cqlsh> SELECT * FROM system.local;
-- query results --
-- trace output --
Tracing session: 12345678-1234-1234-1234-123456789abc

cqlsh> TRACING OFF
Disabled tracing.

Notes

  • TRACING with no argument disables tracing (same as TRACING OFF).
  • Trace output is displayed after each query result.
  • To view a trace later, use SHOW SESSION <trace-uuid>.
  • The maximum wait time for trace data is controlled by [tracing] max_trace_wait in cqlshrc.
