NAME¶
ptop
— display and
update sorted information about processes
SYNOPSIS¶
ptop
[--debug
]
DESCRIPTION¶
ptop
periodically displays a sorted list
of system processes. Processes are sorted with the highest CPU users at the
top. CPU usage is measured from when ptop
was
started, to make the list stabilize over time.
The top screen line shows you the system load. The number tells you how many processes want to run right now, check getloadavg(3) for details.
The histogram shows you how system load has evolved over the last fifteen minutes. The current system load is at the right of the histogram.
The green / yellow / red bar shows you the current system load in relation to the number of cores on the system. Green means load on physical cores, yellow means load on logical cores, and red means that the system load is higher than the number of cores available on the system.
To exit ptop
, press
‘q
’.
With the --debug
flag, extra log messages
are sometimes printed after ptop
finishes.
PROCESS NAMING¶
ptop
tries to be helpful about naming
processes, and avoid printing names of various VMs.
For example, if you do ‘java -jar
foo.jar
’, ptop
will show this process
as ‘foo.jar
’ rather than
‘java
’.
ptop
parses command lines from:
- Java
- Python
- Node
- Ruby
- Various shells
- Perl
