Tasks, Monitoring

This section describes the most basic administration commands that allow you to monitor and control tasks running in the system.

The command

# stats

lists the tasks running in the system along with their task ID and other information.

You can kill a task by running

# kill <task-id>

Now you can check with stats that the command has indeed been killed. If it still appears in the listing, it probably means it is waiting to receive an answer for one of its IPC requests. While the task is in memory, it does not perform any computation anymore (this situation is slightly similar to having a zombie process in UN*X).

To see which tasks consume most CPU time and memory, run

# top

This is an interactive monitoring command, similar to Linux top.
