bigpanda.json

{
  "bigpanda": {
    "token": "TOKEN HERE"
  }
}

bigpanda.rb

##
## Handle events and sends them to BigPanda API.
##
## If you have the template, you should set the TOKEN placeholder (in curly brackets) to your organization token.
## More details at https://a.bigpanda.io/#/app/integrations/sensu/instructions (you must login first)
##
## This is an edit of BigPanda's official sensu handler made into an extension
##
## The benefit to an extension is sensu won't fork a new process for each even it has to send
## to BigPanda. The resulting forking can add excess load to the server.
