error reading file - ENOENT: No such file or directory @ rb_sysopen

Question

I just started exploring smashing (formerly known as dashing).

Based on url here, https://github.com/Shopify/dashing/wiki/Dashing-Workshop

What i am trying to do is just a simple read from local file.

The local file are located in other directory,name googlestatus and it contain:

connected

the jobs/ops.orb contain:

gstatus = puts File.read(./status/googlestatus)

############ scheduler
SCHEDULER.every '1s', :first_in => 0 do |job|
  send_event('response_time', { value: gstatus })
end

but when i run smashing start, it gave me the error below:

A couple of things are wrong with your code:

You need to put the name of the file in quotes in your code, i.e.:
```
puts File.read("./status/googlestatus")
```
Right now, you are (attempting to) read the contents of the file only once during startup. Its once-read value will then be send every seconds without ever being read again. You might want to put the reading of the file into the scheduled block.
Finally, it appears that the file you are attempting to read from doesn't exist (yet) during startup.
