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

283
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 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
# Set the interval for identifying a kernel thread deadloop to 8 seconds.
<Sysname> system-view
[Sysname] monitor kernel deadloop time 8
