README

        
PlugFprof

=========

A Plug that adds fprof tracing to a web app.

### Usage

Add to your dependencies in `mix.exs`:

```elixir

  defp deps do

    [{:plug_fprof, "~> 0.0.1"}]

  end

```

Then `use` it from within your plug/pheonix router:

```elixir

defmodule MyRouter do

  use Plug.Router

  use PlugFprof

end

```

FProf will write it's tracing data into `fprof.trace`.  You can profile &

analyze this from `iex`:

```

iex(1)> :fprof.profile()

Reading trace data...

.........

End of trace!

:ok

iex(2)> :fprof.analyse([dest: 'analysis.txt', cols: 120, callers: true, sort:

:own, totals: true, details: true])

Processing data...

Creating output...

Done!

:ok

```
