prometheus
Allow source_ip as a parameter
In our use cases, we have machines that have potentially hundreds of virtual interfaces, sitting in different networks We'd like to set the source IP as a parameter instead of having to create ICMP and TCP probers for each interface we have.
I guess concerns are similar as in #1098, in the sense that this could enable probing a private network via proxy (which is exactly what we want in this case), so I would suggest also a config flag to allow this. We don't mind the security issues because the BBE is targeted by a local prometheus instance and is not available from the outside.
What is the fate of #1098 ? I'm not per say extremely interested in dynamic probes (though it's really cool), as most of my config is still static, and AFAIU the dynamic probing doesn't combine config file with http parameters
