Btw, what does [this comment](https://github.com/newrelic/elixir_agent/blob/master/lib/new_relic/telemetry/ecto.ex#L7) mean?
How do i make `ecto` depend on `new_relic_agent`?

[Vince Foley]

Hi there, do you happen to have a file called tmp in the root of your project directory? The agent is trying to write a log file to tmp/new_relic.log

You can configure the logs to go elsewhere if you choose: https://hexdocs.pm/new_relic_agent/NewRelic.Config.html#logger/0

How do i make ecto depend on new_relic_agent?

This says "your Ecto app" should depend on the agent... the app that starts the Ecto Repo, not ecto itself
