Hi Brian,
Thanks for such clarification. This is a sample one. We want to monitor
much time http_server_requests_seconds_count is being hit with keeping
application="marketplace-service",
uri="/marketplace/live/bid/{auctionId} as filter and every time a post
request is being made it can be count as 1,2,3 and so on. We will only
change the uri in filter rest things are same.
