Add new tags for default rails metrics

[srikanth3006]

Hi,

I have configured yabeda-rails for my rails project and added the following contents in the initializers/prometheus.rb file

Yabeda.configure do counter : counter1, tags: [%s[tag_name]] end

For every API request, i am getting the below default rails metrics

rails_view_runtime_seconds_bucket{controller="controller_name",action="create",status="200",format="html",method="post",le="0.005"} 1.0

I want to add one more tag to the above metric (in fact for all the default rails metrics) which is coming from incoming request.

Ex: i want to add request.subdomains as an additional tag to the above default metrics.

Please help me on how can i do that? Thanks

I was able to get achieve this after adding the below function in my existing base controller.

def append_info_to_payload(payload)
super
new_tag = request.subdomains
payload[:new_tag] = new_tag
end
