将我的Heroku应用程序移至Unicorn后，New Relic停止显示除部署之外的任何报告。我尝试了这里建议的解决方案：https://newrelic.com/docs/ruby/no-data-with-unicorn没有运气。我尝试更新所有宝石，现在我收到错误：

有什么想法吗？

我也一样。将以下代码添加到config/initializers/newrelic.rb：
# Ensure the agent is started using Unicorn.
# This is needed when using Unicorn and preload_app is not set to true.
# See https://newrelic.com/docs/ruby/no-data-with-unicorn
if defined? Unicorn
::NewRelic::Agent.manual_start()
::NewRelic::Agent.after_fork(:force_reconnect => true)
