By default the output is sorted by CPU usage (column %CPU, shortcut Shift + P). Use
following shortcuts to change the sort field:
Shift + M: Resident Memory (RES)
Shift + N: Process ID (PID)
Shift + T: Time (TIME+)
To use any other field for sorting, press F and select a field from the list. To toggle
the sort order, Use Shift + R.
The parameter -U UID monitors only the processes associated with a particular
user. Replace UID with the user ID of the user. Use top -U $(id -u) to show
processes of the current user
2.3.5 System z hypervisor monitor:
hyptop
hyptop provides a dynamic real-time view of a System z hypervisor environment,
using the kernel infrastructure via debugfs. It works with either the z/VM or the
LPAR hypervisor. Depending on the available data it, for example, shows CPU and
memory consumption of active LPARs or z/VM guests. It provides a curses based
user interface similar to the top command. hyptop provides two windows:
• sys_list: Shows a list of systems that the currently hypervisor is running
• sys: Shows one system in more detail
You can run hyptop in interactive mode (default) or in batch mode with the -b op-
tion. Help in the interactive mode is available by pressing ? after hyptop is started.
