Parameters
slot slot-number: Specifies a card by its slot number. If you do not specify this option, the active MPU
is specified. (In standalone mode.)
chassis chassis-number slot slot-number: Specifies a card on an IRF member device. If you do not
specify this option, the global active MPU is specified. (In IRF mode.)
cpu cpu-number: Specifies a CPU by its number.
core core-number&<1-64> ]: Specifies a maximum of 64 CPU cores. If you do not specify this option,
the command applies to all cores of the specified CPU.
Usage guidelines
Inappropriate use of the command can cause service problems or system breakdown. Make sure
you understand the impact of the command on your network before you use it.
Kernel threads share resources in kernel space. If a kernel thread monopolizes the CPU for a long
time, other threads cannot run, resulting in a deadloop.
This command enables the device to detect deadloops. If a thread occupies the CPU regularly, the
device considers that a deadloop has occurred.
Examples
# Enable kernel thread deadloop detection.

[Sysname] monitor kernel deadloop enable

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