riemann-dash 0.1.1 gem: start_chart: no method nan? for fixnum

[ianrumford]

Using the 0.1.1 riemann-dash gem

riemann/dash/helper/renderer.rb method state_chart has the following line:

if s.metric && !(s.metric.nan?)

I do not understand why but this can generate a no method exception nan? for fixnum.

A simple workaround is e.g.

if s.metric && !(s.metric.nan? rescue true)

but this just conceals the underlying problem.

Fixnums couldn't appear there until recently. The newest version of riemann-ruby-client added support. I'm pretty close to obsoleting that whole ruby dash in favor of the realtime js dashboard; you might give /ws a try.

Would be interested to see / try the realtime dash when your're ready. Realtime is where I want to be eventually.

Check out master from riemann-dash and go to localhost:4567/ws :)
