graphite-api Logging for python n00bs

Hi there, I'm trying to write a custom finder etc using graphite-api and all looks good util I get an exception from a render call. I get a 500 back to the browser:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN"> <title>500 Internal Server Error</title> <h1>Internal Server Error</h1> <p>The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.</p>

and in the Apache log:

[Fri Jul 10 15:17:13 2015] [error] No handlers could be found for logger "flask.app"

Is there a simple way to find out what the problem is? I'm using graphite-api 1.0.1 via pip (can't get install from source to work)

Thanks

I added this to the config, but still no exception detail in the apache log or /var/log/graphite-api.log (file is empty)

logging:
  version: 1
  handlers:
    raw:
      level: DEBUG
      class: logging.StreamHandler
      formatter: raw
  loggers:
    root:
      handlers:
        - raw
      level: DEBUG
      propagate: false
    graphite_api:
      handlers:
        - raw
      level: DEBUG

Current master returns tracebacks in the HTTP response in case of app errors. Can you give it a try?

Thanks, but I could only get it to work at all via pip (i.e released version). I got a load of dependency-related problems when I tried to do it from source.

Cool, graphite-api 1.1 was just released and it contains that change.

Yep, got the python trace back now - much easier to debug, thanks!

Is this how I should debug generally? I am still logging into the Apache logfile using print statements which doesn't feel quite right, and still get the "No handlers could be found for logger "flask.app" errors..
