Support for Raspberry PI

I'm trying to set up sampler to work as a dashboard running on a Raspberry PI.
I managed to get it to compile on the PI but when i try to run it i get the following error:

# sampler --config conf.yml
panic: non-positive interval for NewTicker [recovered]
        panic: non-positive interval for NewTicker

Hi @the-louie,
Could you please share your config file?

[the-louie]

I've done som further testing and found the simplest configuration i can find to break and work.

  - title: This works
    rate-ms: 19327
    sample: echo "HELLO WORLD"

  - title: This breaks
    rate-ms: 19328
    sample: echo "HELLO WORLD"

(Both works when I run it on MacOS 10.14)

@the-louie were you able to make it work in rpi? did you build from src and cross compiled to amd64?

[the-louie]

@aysark Yes, ran it for a year without problem. Just compiled it on the Pi, never done any go stuff before so found a guide that I followed and after some tries it worked. 😄
