i am working on creating a new metric in promethus and graphana as the dashboard UI. currently we have a kubernetes ingress controller and we need to send the header data to promethus

(EX : hostname : stackoverflow.com / stackoverflow.in etc )

and the URL path : similar to the API path ex :

1) /api/questions/1234/ask

2) /api/questions/12345/ask

3) /api/questions/123456/ask ) to promethus.

we need to find a way to send the formatted path from ingress to promethus which should be like /api/questions/{id}/ask also

we need to find a way to send the original host from ingress to promethus.

As of now we are not sending this data to promethus

i am new to dashboard stuff can anyone shed some light on how to send those metrics to promethus and create custom metric accordingly.

Regards
