I was wondering if anyone uses Tasseo for their Graphite dashboards. I'm having some problems I dont quite get. Basically, Tasseo polls Graphite server for stats - if you have authentication enabled (http base auth) on your Graphite server then you must export GRAPHITE_URL and GRAPHITE_AUTH environment variables to the environment in which tasseo is running ie. if you run tasseo as runit service then your run script should look like this:
#!/bin/sh
exec 2>&1
export GRAPHITE_URL="https://graphite-url"
export GRAPHITE_AUTH="user:password"
cd /app
exec chpst -u tasseo bundle exec rackup -o 127.0.0.1 -p 5000 -s thin
What I noticed though is that IF I DONT authenticate to the Graphite in the SAME browser in which I'm running Tasseo in another tab (by running I literally mean running as Tasseo is just a sinatra app fully built in javascript ie it's running in your browser), then I'm NOT able to display ANY graphs. As soon as I authenticate against Graphite in the same browser all works fine. Tasseo is using CORS ie. it's polling Graphite from within JavaScript so it might do something with it.
The most annoying thing is that I have to do this every time I restart tasseo app server :-( So when I restart tasseo I have to reload Graphite page - I assume so that is re-authenticates ?
Also I noticed that even though when I reload the Graphite tab, Tasseo works for a while and then after some time (dont have exact measures) it stops working - in Chrome's development console I can see that the OPTIONS requests to Graphite are failing - so the GET requests must too.
Anyone ideas ?
