script.rb

"check":{
         "output":"HTTP CRITICAL: HTTP/1.1 503 Service Temporarily Unavailable - pattern not found - 593 bytes in 0.001 second response time |time=0.000500s;;;0.000000 size=593B;;;0\n",
         bla bla

I need to get the first text before the "|". Tried this:

def foo
    @event['check']['output'].split(' | ').first
  end
  
puts foo

And I still get the full text of "output": HTTP CRITICAL: HTTP/1.1 503 Service Temporarily Unavailable - pattern not found - 593 bytes in 0.001 second response time |time=0.000500s;;;0.000000 size=593B;;;0
