etop
MODULE
MODULE SUMMARY
DESCRIPTION
etop should be started with the provided scripts etop and getop for text based and graphical presentation respectively. Under Windows the batch files etop.bat and getop.bat can be used.
All interaction with etop when running the graphical presentation should happen via the menus. For the text based presentation the functions described below can be used.
The following configuration parameters exist for etop.
- node
- The measured node.
Value: atom()
Mandatory - setcookie
- Cookie to use for the etop node - must be the same
as the cookie on the measured node.
Value: atom() - lines
- Number of lines (processes) to display.
Value: integer()
Default: 10 - interval
- The time interval (in seconds) between each update of
the display.
Value: integer()
Default: 5 - accumulate
- If true the execution time and reductions are
accumulated.
Value: boolean()
Default: false - sort
- Identifies what information to sort by.
Value: runtime | reductions | memory | msg_q
Default: runtime (reductions if tracing=off) - tracing
-
etop uses the erlang trace facility, and thus no
other tracing is possible on the measured node while
etop is running, unless this option is set to
off. Also helpful if the etop tracing causes too
high load on the measured node. With tracing off, runtime is
not measured.
Value: on | off
Default: on
