I have Erlang/OTP 17 [RELEASE CANDIDATE 1] installed and i can't start appmon. I have tried:

appmon:start().
** exception error: undefined function appmon:start/0

I also tried:

l(appmon).

And I get the following error:

{error,nofile}

How can I make appmon work ?

appmon looks to have been removed, in favour of the new observer application. See the note here. There seems to be precious little online documentation on why, but presumably the docs included in your erlang installation would at least help you find how to use it.

As noted in sanmiguel's answer, appmon has been removed.

The solution for me was to use this command instead:

observer:start().

As mentioned above, appmon has been removed starting from R17 along with the gs framework. It is replaced by observer which uses wxWidgets as GUI framework.

In my case where I am using Ubuntu 16.04 (xenial), I need to install libwxgtk3.0-dev which will install any required additional packages. Running 'wx-config --version' gave me the hints on which package to install.

$ wx-config --version
The program 'wx-config' can be found in the following packages:
 * libwxbase3.0-dev
 * libwxgtk3.0-dev
Try: sudo apt install <selected package>
