R0106-HP MSR Router Series Network Management and Monitoring Command Reference(V7)

284
This command enables the system to detect and report thread starvation. If a thread is not executed
within an interval, the system considers that a starvation has occurred, and outputs a starvation message.
Thread starvation does not impact system operation. A starved thread can automatically run when
certain conditions are met.
Inappropriate use of this command can cause service problems or system breakdown. Make sure you
understand the impact of this command on your network before you use it.
Examples
# Enable kernel thread starvation detection.
<Sysname> system-view
[Sysname] monitor kernel starvation enable

thread.
Use undo monitor kernel starvation exclude-thread to enable kernel thread starvation detection for a
kernel thread.

Parameters
tid: Specifies a kernel thread by its ID, in the range of 1 to 2147483647. If no kernel thread is specified
for the undo command, the default is restored.
slot slot-number: Specifies an MPU by its slot number. If you do not specify this option, the active MPU is
specified. (MSR4000.)
