Process monitoring and maintenance commands
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, "process" refers to both user processes and kernel threads.
display exception context
Use display exception context to display context information for process exceptions.
Syntax
display exception context [ count value ] [ 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 IRF member device by its member ID or specifies a PEX by its virtual slot number. If you do not specify a member device or PEX, this command displays information for the master device.
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 file directory, stack information, and register information.
Examples
# Display the exception context information on the x86-based 32-bit device.

· Data memory—Stores data for the user process.
· Stack memory—Stores temporary data.
· Dynamic memory—Heap memory dynamically assigned and released by the system according to the needs of the user process. To view dynamic memory information, execute the display process memory heap command.

network-operator
Parameters
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 an IRF member device by its member ID or specifies a PEX by its virtual slot number. If you do not specify a member device or PEX, this command displays information for the master device.
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 148.
<Sysname> display process memory heap job 148
Total virtual memory heap space(in bytes) : 2228224
Total physical memory heap space(in bytes) : 262144

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 an IRF member device by its member ID or specifies a PEX by its virtual slot number. If you do not specify a member device or PEX, this command displays information for the master device.
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.

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.
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.
slot slot-number: Specifies an IRF member device by its member ID or specifies a PEX by its virtual slot number. If you do not specify a member device or PEX, this command displays information for the master device.
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.
Commands |
Description |
? or h |

Field |
Description |
84 processes; 107 threads |
Numbers of processes and threads. |
JID |
Job ID of a thread, which never changes. |
TID |
ID of a thread. |
LAST_CPU |
Number of the CPU on which the latest thread scheduling occurs. |
PRI |
Priority level of a thread. |
State |
State of a thread: · R—Running. · S—Sleeping. · T—Traced or stopped. · D—Uninterruptible sleep. · Z—Zombie. |
HH:MM:SS |
Running time of a thread since last restart. |
MAX |
Longest time that a single thread scheduling occupies the CPU, in milliseconds. |
CPU |
CPU usage of a thread. |
Name |

process core
Use process core to enable or disable a process to generate core files for exceptions and set the maximum number of core files.
Syntax
process core { maxcore value | off } { job job-id | name process-name } [ slot slot-number [ cpu cpu-number ] ]
Views
User view
Default
A process generates a core file for the first exception and does not generate any core files for subsequent exceptions.
Predefined user roles
network-admin
Parameters
off: Disables core file generation.
maxcore value: Enables core file generation and sets the maximum number of core 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 an IRF member device by its member ID or specifies a PEX by its virtual slot number. If you do not specify a member device or PEX, this command displays information for the master device.
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 file each time the specified process crashes until the maximum number of core files is reached. A core file records the exception information.
Because the core files consume system storage resources, you can disable core file generation for processes for which you do not need to review exception information.
Examples
# Disable core file generation for process routed.
<Sysname> process core off name routed
# Enable core file generation for process routed and set the maximum number of core files to 5.
<Sysname> process core maxcore 5 name routed
