Currently we can see "CPU", "Memory" and "Network" metrics. Coming from Heroku, I am missing the "response time" (of HTTP requests) and the "throughput" (number of requests broken down by HTTP status code (1XX, 2XX, 3XX, 4XX and 5XX). On top of it, users should be allowed to set automatic alerts (e.g. when getting a 5xx status code, an email is sent to the administrator).
