Graphite HTTP Request Error

[sammcj]

My graphiteUrl is configured as:

graphiteUrl: "http://graphite.mydomain.com",

visiting this url returns the standard graphite API page of 'no data' which is correct if no parameters have been passed to it.

Do you not get the standard graphite web page? Or are you using graphite - api ?

[torkelo]

Please show result from chrome network tab, so I can see what error graphite render request returns

[lefthand]

Hello, it appears I'm hitting the same error. When I access the page in the browser it comes up correctly. Here is the response I got from the network tab.

https://gist.github.com/lefthand/e024da2eeaece6edf881

I'm running grafana in a vagrant instance locally while the graphite host is in a real server.

I updated that gist with a little more / clearer information. The error is:

Exception Value: 'NoneType' object has no attribute 'startswith'

I noticed that I'm able to edit queries and it pulls in all the correct data so I can construct queries but I still get the 500 error when rendering the actual graph.

@lefthand what is the graphite query you are trying this with? Graphite seems to think it is not a valid query.

[lefthand]

This happens with any query:

randomWalk('random walk')

Thanks for looking at at this @torkelo (and thanks again for the shirt and Monitorama!)

I discovered that my graphite install only seems to like GET requests and not POST. Once I added

render_method: 'GET'

to my graphite settings that seems to have solved the problem for me. I tried added POST to Access-Control-Allow-Methods on my graphite apache config file but that didn't seem to help. I'd love to fully understand it but I'm happy for now.

@sammcj Does this solve your problem as well? Reading over issue #345 helped me sort it out.
