[erlang-questions] Erlang program and bash/Munin communication

[Matthew Evans]

You could try erl_call

http://www.erlang.org/doc/man/erl_call.html

Or escript called from bash.

erl_call is normally hidden in the Erlang release somewhere, not in the default path.

Subject: [erlang-questions] Erlang program and bash/Munin communication

Hi Dear Erlangers!
I want to plot some stats from my Erlang program in munin (http://munin-monitoring.org/). For that I have to call it somehow from bash/sh script. Standart munin setup calls the script every 5 minutes.


So, I want to know, what is a best way to establish one way (Erlang -> Bash) communication?
One of approaches could be when Erlang program writes file to somewhere like /var/run/erl-prog and bash script reads it.


Is there are any other simpler options available?
p.s. I know that ejabberd has some interface to bash, but its code too complex to my task.Best regards,

Max
