Hi,

currently the nginx-vts-exporter supports Server requests (1xx, 2xx etc.) and Upstream requests (1xx, 2xx etc.), but what would also be neat is feature already provided by vts plugin -- Upstream requests per backend. Backends are already working for nginx_upstream_requestMsec and nginx_upstream_responseMsec so, I'm assuming here, I think this should not be super difficult to implement.

Current state:

nginx_upstream_requests{code="1xx",instance="$INSTANCE",job="$JOB",upstream="$UPSTREAM"}

Feature request state:

nginx_upstream_requests{backend="$BACKEND",code="1xx",instance="$INSTANCE",job="$JOB",upstream="$UPSTREAM"}

Please let me know whether there's anything not clear about the issue.

All the best
Filip
