installing backstop

[skotzkoj]

Hi
I've attempted to install backstop into an Ubuntu 15 vm where I have Graphite also installed. I followed the steps with the following settings:

$ cd /tmp/
git clone https://github.com/obfuscurity/backstop.git
$ cd backstop
$ bundle install
$ export CARBON_URLS= "carbon://localhost:2003"
$ export PREFIXES= test,system_io_by_size,system_totals
$ foreman start

All works as expected so far. How ever when I try to formulate a rest post command the example provided indicates backstop is listening on port 443, but I find no process that is running on this port. I found the process kicked off after foreman start is listening on port 5000 but rest commands to this port return this:

command I run from within my vm:
graphite@jeffs-ubuntu:~/backstop$ curl --data '{"metric" :"test" , "value" : "100", "measure_time" : "2016-07-01"}' http://localhost:5000/publish/note

error returned:

ENV:

help a noob out?

Thanks in advance.

@skotzkoj Sorry for the slow response. I'm not sure why I put an https protocol scheme in the example config, it doesn't support https natively (although it could with a little work). It's been so long I just don't remember why it was documented like that.

As far as your PREFIXES issue, your export command looks invalid. Can you run echo $PREFIXES to make sure it has a valid string?

Oh, wrt the https scheme I was probably using Heroku's SSL feature.
