NAMEetop - Erlang Top is a tool for presenting information about Erlang processes similar to the information presented by "top" in UNIX.DESCRIPTIONStart Erlang Top with the provided scripts etop. This starts a hidden Erlang node that connects to the node to be measured. The measured node is specified with option -node. If the measured node has a different cookie than the default cookie for the user who invokes the script, the cookie must be explicitly specified with option -setcookie.Under Windows, batch file etop.bat can be used. When executing the etop script, configuration parameters can be specified as command-line options, for example, etop -node testnode@myhost -setcookie MyCookie. The following configuration parameters exist for the tool:
Value: atom() Mandatory
Value: atom()
Value: integer() Default: 10
Value: integer() Default: 5
Value: boolean() Default: false
Value: runtime | reductions | memory | msg_q Default: runtime (reductions if tracing=off)
Value: on | off Default: on For details about Erlang Top, see the User's Guide. EXPORTSstart() -> okStarts etop. Notice that etop is preferably started with the etop script. start(Options) -> ok
Types: Options = [Option]
Option = {Key, Value} Key = atom() Value = term() Starts etop. To view the possible options, use help/0. help() -> ok
Displays the help of etop and its options. config(Key,Value) -> Result
Types: Result = ok | {error,Reason}
Key = lines | interval | accumulate | sort Value = term() Changes the configuration parameters of the tool during runtime. Allowed parameters are lines, interval, accumulate, and sort. dump(File) -> Result
Types: Result = ok | {error,Reason}
File = string() Dumps the current display to a text file. stop() -> stop
Terminates etop.
