%description
exporter_exporter provides a simple reverse proxy for Prometheus exporters. 
It is intended as a single binary alternative to Nginx or Apache for use 
in environments where opening multiple TCP ports to all servers might be 
difficult due to firewalls or policy constraints.

The advantages are:

* A single port can be used to query multiple exporters (to ease firewall configuration concerns).
* Can provide TLS with optional client certificate authentication.
* Provides verification that the target is serving prometheus metrics.
* Can be used to execute scripts that produce prometheus metrics.
* up behaviour is the same as for querying individual collectors.
* Small code size, minimal external depedencies, easily auditable.
