The display memory, display process, display process cpu, monitor process and monitor thread commands display information about both user processes and kernel threads. In these commands, the term "process" refers to both user processes and kernel threads.

display exception context

Use display exception context to display context information for process exceptions.

Syntax

In standalone mode:

display exception context [ count value ] [ slot slot-number [ cpu cpu-number ] ]

In IRF mode:

display exception context [ count value ] [ chassis chassis-number slot slot-number [ cpu cpu-number ] ]

Views

Any view

Predefined user roles

network-admin

Parameters

count value: Specifies the number of context information entries, in the range of 1 to 20. The default value is 1.

slot slot-number: Specifies an MPU by its slot number. If you do not specify this option, the command displays context information for process exceptions on the active MPU. (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 command displays context information for process exceptions on the global active MPU. (In IRF mode.)

cpu cpu-number: Specifies a CPU by its number.

Usage guidelines

The system generates a context information entry for each process exception. A context information entry includes the process ID, the crash time, the core dump file directory, stack information, and register information.

Examples

# Display the exception context information on the device.

<Sysname> display exception context

Parameters

show-number: Specifies the number of kernel thread reboots to display, in the range of 1 to 60.

offset: Specifies the offset between the starting reboot and the most recent reboot, in the range of 0 to 59. The default value is 0.

verbose: Displays detailed information. If you do not specify this keyword, the command displays brief information.

slot slot-number: Specifies an MPU by its slot number. If you do not specify this option, the command displays kernel thread reboot information for the active MPU. Reboot information for cards is recorded in the memory of the active MPU. If the active MPU is powered off, the reboot information is lost. (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 command displays kernel thread reboot information for the global active MPU. Reboot information for cards on an IRF member device is recorded in the memory of the active MPU on the IRF member device. If the active MPU is powered off, the reboot information is lost. (In IRF mode.)

cpu cpu-number: Specifies a CPU by its number.

job job-id: Specifies a user process by its job ID, in the range of 1 to 2147483647.

verbose: Displays detailed information. If you do not specify this keyword, the command displays brief information.

slot slot-number: Specifies a card by its slot number. If you do not specify this option, the command displays heap memory usage for the user process on the active MPU.(In standalone mode.)

cpu cpu-number: Specifies a CPU by its number.

Usage guidelines

Heap memory comprises fixed-sized blocks such as 16-byte or 64-byte blocks. It stores data and variables used by the user process. When a user process starts, the system dynamically allocates heap memory to the process.

Each memory block has an address represented in hexadecimal format, which can be used to access the memory block. You can view memory block addresses by using the display process memory heap size command, and view memory block contents by using the display process memory heap address command.

Examples

# Display brief information about heap memory usage for the process identified by job ID 1.

<Sysname> display process memory heap job 1

Total virtual memory heap space(in bytes) : 2228224

Total physical memory heap space(in bytes) : 262144

Total allocated memory(in bytes) : 161576

# Display detailed information about heap memory usage for the process identified by job ID 1.

Usage guidelines

Use this command only under the guidance of H3C technical support staff. Inappropriate configuration can cause system breakdown.

Starvation occurs when a thread is unable to access shared resources.

The 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.

Parameters

dumbtty: Specifies dumbtty mode. In this mode, the command displays process statistics in descending order of CPU usage without refreshing statistics. If you do not specify this keyword, the command displays statistics for the top 10 processes in descending order of CPU usage in an interactive mode, and refreshes statistics every 5 seconds by default.

iteration number: Specifies the number of display times, in the range of 1 to 4294967295. If you specify the dumbtty keyword, the number argument is 1 by default. If neither the dumbtty keyword nor the number argument is specified, there is no limit to the display times and process statistics are refreshed every 5 seconds.

slot slot-number: Specifies a card by its slot number. If you do not specify this option, the command displays process statistics for the active MPU.(In standalone mode.)

cpu cpu-number: Specifies a CPU by its number.

Usage guidelines

If you do not specify the dumbtty keyword, the command displays process statistics in an interactive mode. In this mode, the system automatically determines the number of displayed processes according to the screen size, and does not display exceeding processes. You can also input interactive commands as shown in Table 12 to perform relevant operations.

Table 12 Interactive commands

Commands	Description
? or h	Displays help information that includes available interactive commands.
1	Displays state information for physical CPUs. For example, if you enter 1 for the first time, the state of each physical CPU is displayed in a separate row. If you enter 1 again, the average value of all CPU states is displayed. If you enter 1 for the third time, separate states are displayed. By default, the average value of all CPU states is displayed.
c	Sorts processes by CPU usage in descending order, which is the default setting.
d	Sets the interval for refreshing process statistics, in the range of 1 to 2147483647 seconds. The default value is 5 seconds.
f	Sorts processes by the number of open files in descending order. Files are identified by file descriptors (FDs).
k	Kills a process. Because the command can impact system operation, be cautious to use it.
l	Refreshes the screen.
m	Sorts processes by memory usage in descending order.
n	Changes the maximum number of processes displayed within a screen, in the range of 0 to 2147483647. The default value is 10. A value of 0 means no limit. Only processes not exceeding the screen size can be displayed.
q	Quits the interactive mode.
t	Sorts processes by running time in descending order.
<	Moves sort field to the next left column.
>	Moves sort field to the next right column.

Parameters

dumbtty: Specifies dumbtty mode. In this mode, the command displays all thread statistics in descending order of CPU usage without refreshing statistics. If you do not specify the keyword, the command displays statistics for top 10 processes in descending order of CPU usage in an interactive mode, and refreshes statistics every 5 seconds by default.

slot slot-number: Specifies a card by its slot number. If you do not specify this option, the command displays thread statistics for the active MPU. (In standalone mode.)

cpu cpu-number: Specifies a CPU by its number.

Usage guidelines

If you do not specify the dumbtty keyword, the command displays thread statistics in an interactive mode. In this mode, the system automatically determines the number of displayed thread processes according to the screen size and does not display exceeding processes. You can also input interactive commands as shown in Table 14 to perform relevant operations.

Table 14 Interactive commands

Commands	Description
? or h	Displays help information that includes available interactive commands.
1	Displays one of the following items in turn when you press 1 again and again: · Values of parameters of physical CPUs. · Average values of parameters of all CPUs. By default, the command displays the average values of parameters of all CPUs.
c	Sorts statistics by CPU usage in descending order. By default, the command sorts statistics by CPU usage in descending order.
d	Sets the interval for refreshing statistics. The default interval is 5 seconds.
k	Kills a process. Because the command can impact system operation, be cautious when you use it.
l	Refreshes the screen.
n	Changes the maximum number of threads displayed within a screen, in the range of 0 to 2147483647. The default value is 10. A value of 0 means no limit. Only threads not exceeding the screen size can be displayed.
q	Quits interactive mode.
t	Sorts statistics by the running time since the latest startup.
<	Moves sort field to the next left column.
>	Moves sort field to the next right column.

process core

Use process core to enable core dump for a process and set the maximum number of core dump files or disable core dump for a process.

Syntax

In standalone mode:

process core { maxcore value | off } { job job-id | name process-name } [ slot slot-number [ cpu cpu-number ] ]

In IRF mode:

process core { maxcore value | off } { job job-id | name process-name } [ chassis chassis-number slot slot-number [ cpu cpu-number ] ]

Views

User view

Default

A process generates a core dump file for the first exception and does not generate any core dump files for subsequent exceptions.

Predefined user roles

network-admin

Parameters

off: Disables core dump.

maxcore value: Enables core dump and sets the maximum number of core dump files, in the range of 1 to 10.

name process-name: Specifies a process by its name, a case-insensitive string of 1 to 15 characters.

job job-id: Specifies a process by its job ID, in the range of 1 to 2147483647. The job ID does not change after the process restarts.

slot slot-number: Specifies a card by its slot number. If you do not specify this option, the command is applied to the active MPU. (In standalone mode.)

chassis chassis-number slot slot-number: Specifies a card on an IRF member device. The chassis-number argument represents the member ID of the IRF member device. The slot-number argument represents the slot number of the card. If you do not specify a card, the command is applied to the global active MPU. (In IRF mode.)

cpu cpu-number: Specifies a CPU by its number.

Usage guidelines

The command applies to all instances of a process.

The command enables the system to generate a core dump file each time the specified process crashes until the maximum number of core dump files is reached. A core dump file stores information about the process.

Core dump files consume storage resources. Enable core dump only for processes that might have problems

Examples

# Disable core dump for process routed.

<Sysname> process core off name routed

# Enable core dump for process routed and set the maximum number of core dump files to 5.

<Sysname> process core maxcore 5 name routed
