What is Kernel Logging?

Kernel Logging is an infrastructure for tracking and logging speciﬁed behaviors during

HP-UX system operation. It enhances the high availability of the operating system by

providing enough kernel trace information to enable a system administrator or other

troubleshooter to diagnose the root cause of a system problem without needing to reboot the

system or reproduce the problem.

Kernel Logging has two main parts: an instrumented kernel, and a framework of tools to

conﬁgure and access the information that is logged. Likewise, this document has two main

sections:

❏ “Instrumenting Kernel Subsystems for Kernel Logging” on page 4, is intended for kernel

developers.

❏ “Using Kernel Logging” on page 10, is intended for system administrators and other

troubleshooters.
