nginx_ingress_controller_requests is missing for Ingress

[banbridge]

After fresh installed nginx ingress controller with metrics enabled. we are not able to see few metrics.

go_goroutines Number of goroutines that currently exist. go_goroutines gauge nginx_ingress_controller_bytes_sent The number of bytes sent to a client nginx_ingress_controller_bytes_sent histogram nginx_ingress_controller_ingress_upstream_latency_seconds Upstream service latency per Ingress nginx_ingress_controller_ingress_upstream_latency_seconds summary nginx_ingress_controller_request_duration_seconds The request processing time in milliseconds nginx_ingress_controller_request_duration_seconds histogram nginx_ingress_controller_request_size The request length (including request line, header, and request body) nginx_ingress_controller_request_size histogram nginx_ingress_controller_requests The total number of client requests. nginx_ingress_controller_requests counter nginx_ingress_controller_response_duration_seconds The time spent on receiving the response from the upstream server nginx_ingress_controller_response_duration_seconds histogram nginx_ingress_controller_response_size The response length (including request line, header, and request body) nginx_ingress_controller_response_size histogram
