New Relic - Requests Per Minute

Note: To utilize the New Relic API v2, you must subscribe to the "Pro" plan or use the free New Relic add-on available through Heroku.

Note: New Relic may take up to 4 minutes to process ingested metrics from your application. Consequently, the metric data that HireFire relies on for autoscaling could be delayed by approximately 6 minutes. If this latency poses a problem, you might want to consider using either the HireFire or Logplex strategies. See Guides.
