NAME¶

SYNOPSIS¶
ptop
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
’.
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
