Server Monitoring

As you might expect from a platform that has been running demanding and critical applications for 20 years, Erlang has great server-monitoring tools.

One of the easiest to use is already baked in. Inside IEx, run

​	​iex>​ ​:observer​.start()

Use this to get insight into…

• Basic system information:

  

• Dynamic charts of load:

  

• Information and contents of Erlang ETS tables:

  

• Running processes:

  

• Running applications:

  

• Memory allocation:

  

• And tracing of function calls, messages, and events:
