display process memory heap
Use display process memory heap to display heap memory usage for a user process.
Syntax
Centralized devices in standalone mode:
display process memory heap job job-id [ verbose ]
Distributed devices in standalone mode/centralized devices in IRF mode:
display process memory heap job job-id [ verbose ] [ slot slot-number [ cpu cpu-number ] ]
Distributed devices in IRF mode:
display process memory heap job job-id [ verbose ] [ chassis chassis-number slot slot-number
[ cpu cpu-number ] ]
Views

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 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. (Distributed devices in
standalone mode.)
slot slot-number: Specifies an IRF member device by its member ID. If you do not specify a member
device, this command displays information for the master device. (Centralized devices in IRF 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, this command displays
information for the global active MPU. (Distributed devices in IRF mode.)
cpu cpu-number: Specifies a CPU by its number. (Centralized devices in IRF mode/distributed
devices in IRF or standalone mode.)
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
