Kernel thread starvation detection enables the system to detect and report thread starvation. If a thread
is not executed within a specific interval, the system considers that a starvation has occurred, and
generates a starvation message.
Thread starvation does not impact system operation. A starved thread can automatically run when
certain conditions are met.
To configure kernel thread starvation detection (in standalone mode):
Ste
p
Command Remarks
1. Enter system view.
system-view N/A
2. Enable kernel thread
starvation detection.
monitor kernel starvation enable [ slot
slot-number ]
By default, the function is
disabled.
3. (Optional.) Set the interval
for identifying a kernel
thread starvation.
monitor kernel starvation time interval [ slot
slot-number ]
The default is 120 seconds.
4. (Optional.) Disable kernel
thread starvation detection
for a kernel thread.
monitor kernel starvation exclude-thread
tid [ slot slot-number ]
After enabled, kernel thread
starvation detection monitors
all kernel threads by default.
To configure kernel thread starvation detection (in IRF mode):
Ste
p
Command Remarks
1. Enter system view.
system-view N/A
2. Enable kernel thread
starvation detection.
monitor kernel starvation enable [ chassis
chassis-number slot slot-number ]
By default, the function is
disabled.
3. (Optional.) Set the interval
for identifying a kernel
thread starvation.
monitor kernel starvation time interval
[ chassis chassis-number slot slot-number ]
The default is 120 seconds.
4. (Optional.) Disable kernel
thread starvation detection
for a kernel thread.
monitor kernel starvation exclude-thread
tid [ chassis chassis-number slot
slot-number ]
After enabled, kernel thread
starvation detection monitors
all kernel threads by default.
Displaying and maintaining kernel threads
Execute display commands in any view and reset commands in user view (in standalone mode).
