traceoptions (Health Check Monitoring)

Syntax

Hierarchy Level

Description

CAUTION:

Enabling tracing can adversely impact scale and performance and may increase security risk. We strongly recommend using the trace, tracing, or traceoptions commands only under the guidance of a JTAC support engineer. After collecting the debug information, immediately disable tracing to minimize risk and restore normal system performance.

Specify tracing options for the traffic load balancer health check monitoring function.
