sinatra-health-check
This tiny gem adds graceful stop to your sinatra application.
Stopping apps gracefully allows your running requests to finish before killing the app. It gives some time to configure load balancers before shutting things down.
Usage
Initialize the health check:
require 'sinatra-health-check'
@checker = SinatraHealthCheck::Checker.new
Optionally add subsystems to the Checker:
# mysubsystem responds to :status with a SinatraHealthCheck::Status object
@checker.systems[:mysubsystem] = mysubsystem
Then use it inside your health check route:
get "/internal/health" do
if @checker.healthy?
"healthy"
else
status 503
"unhealthy"
end
end
Deliver a status document showing overall health/status and status of all subsystems:
get "/internal/status" do
headers 'content-type' => 'application/json'
@checker.status.to_json
end
