The following configuration parameters exist for the etop tool. When executing the etop script, these parameters can be given as command line options, e.g. etop -node testnode@myhost -setcookie MyCookie.
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 |
