Monitor Kernel Deadloop Time - HPE FlexNetwork 7500 Series Network Management And Monitoring Command Reference

monitor kernel deadloop time

monitor kernel deadloop time
Use monitor kernel deadloop time to set the interval for identifying a kernel thread deadloop.
Use undo monitor kernel deadloop time to restore the default.
Syntax
In standalone mode:
monitor kernel deadloop time interval [ slot slot-number [ cpu cpu-number ] ]
undo monitor kernel deadloop time [ slot slot-number [ cpu cpu-number ] ]
In IRF mode:
monitor kernel deadloop time interval [ chassis chassis-number slot slot-number [ cpu
cpu-number ] ]
undo monitor kernel deadloop time [ chassis chassis-number slot slot-number [ cpu
cpu-number ] ]
Default
The interval for identifying a kernel thread deadloop is 8 seconds.

Parameters
time interval: Specifies the interval for identifying a kernel thread deadloop, in the range of 1 to
65535 seconds.
slot slot-number: Specifies an MPU 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 an MPU 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.
Usage guidelines
If a kernel thread runs for the specified interval, kernel thread deadloop detection considers that a
deadloop has occurred. The system records the deadloop and restarts.
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.
