我正在使用New Relic监视我的Rails 4.2应用程序,并且运行良好。
但是,当New Relic向我报告一个用户时,我希望能够知道哪个用户遇到了错误。
我已经读过这篇文章,我相信这可以解释如何在每个控制器的基础上添加自定义属性。
但是,就我而言,我想记录current_user.id为整个应用程序的自定义属性。
我首先想到的是将以下内容放入applications_controller.rb:
class ApplicationController < ActionController::Base
::NewRelic::Agent.add_custom_parameters(
:user_name => current_user.full_name rescue "Not a logged-in user.",
:user_id => current_user.id rescue "Not a logged-in user."
)

...但这导致服务器错误。
有什么建议么?
更新/解决方案
我在上面所做的事情有两个问题。首先,我使用rescue不当。其次,我需要创建一个方法添加这些自定义属性和调用该方法在ApplicationController使用之前的一切before_filter。这是最终为我工作的示例:
class ApplicationController < ActionController::Base
# attempt to gather user and organization attributes before all controller actions for New Relic error logging
before_filter :record_new_relic_custom_attributes
def record_new_relic_custom_attributes
# record some custom attributes for New Relic
new_relic_user_id = current_user.id rescue "Not a logged-in user."
new_relic_user_name = current_user.full_name rescue "Not a logged-in user."
new_relic_user_email = current_user.email rescue "Not a logged-in user."
new_relic_organization_id = current_organization.id rescue "Not a logged-in user."
new_relic_organization_name = current_organization.name rescue "Not a logged-in user."
new_relic_organization_email = current_organization.email rescue "Not a logged-in user."
::NewRelic::Agent.add_custom_parameters(
:user_id => new_relic_user_id,
:user_name => new_relic_user_name,
:user_email => new_relic_user_email,
:organization_id => new_relic_organization_id,
:organization_name => new_relic_organization_name,
:organization_email => new_relic_organization_email
)
end

根据下面的评论者之一,rescue在这种情况下使用不是理想的,我应该使用try:
new_relic_user_id = current_user.try(:id) || "Not a logged-in user."

您可能希望将该代码包含在过滤器中,以使其在控制器操作之前运行,例如:
class ApplicationController < ActionController::Base
before_filter :set_new_relic_user
def set_new_relic_user
::NewRelic::Agent.add_custom_parameters(
:user_name => current_user.full_name rescue "Not a logged-in user.",
:user_id => current_user.id rescue "Not a logged-in user."
)
end
