Monitoring and maintaining processes

HPE Comware 7 is a full-featured, modular, and scalable network operating system based on the
Linux kernel. Comware 7 software features run the following types of independent processes:
•
User process—Runs in user space. Most Comware 7 software features run user processes.
Each process runs in an independent space so the failure of a process does not affect other
processes. The system automatically monitors user processes. Comware 7 supports
preemptive multithreading. A process can run multiple threads to support multiple activities.
Whether a process supports multithreading depends on the software implementation.
•
Kernel thread—Runs in kernel space. A kernel thread executes kernel code. It has a higher
security level than a user process. If a kernel thread fails, the system breaks down. You can
monitor the running status of kernel threads.

Displaying and maintaining processes

Commands described in this section apply to both user processes and kernel threads. You can
execute these commands in any view.
The system identifies a process that consumes excessive memory or CPU resources as an anomaly
source.
To display and maintain processes:
Task
Display memory usage.
Display process state
information.
Display CPU usage for all
processes.
Monitor process running state.
Monitor thread running state.
For detailed information about the display memory [ slot slot-number ] command, see
Fundamentals Command Reference.

Displaying and maintaining user processes

Execute display commands in any view and other commands in user view.
Task
Display log information for all
user processes.
Display memory usage for all
user processes.
Display heap memory usage for a
user process.
Display the addresses of memory
