Using OTP's observer (appmon replacement) remotely

$ ssh remote-host "epmd -names"
epmd: up and running on port 4369 with data:
name some_node at port 58769

Note the running on port for epmd itself and the port of the node you're interested in debugging. Reconnect to the remote host with these ports forwarded:

$ ssh -L 4369:localhost:4369 -L 58769:localhost:58769 remote-host

To use hstore in Ecto schemas you have to create own Ecto type. To do this, follow these steps:

1. Create files hstore.ex & hstore_extension.ex inside your lib folder
2. Open your database settings and add the following line

extensions: [{MyApp.HStoreExtension, nil}],, for example

config :my_app, MyApp.Repo,
 adapter: Ecto.Adapters.Postgres,
