npm install statsd-proxyStatsd-Proxy
============
Proxy for etsy/statsd.
Why
---
etsy/statsd comes with a proxy in nodejs,
and we are running it on a single server, proxing a statsd cluster via an
udp port. But we found that this nodejs proxy is losing packets, up to
30~40% sometimes!
Cpus are idle but packets are being lost. In our case, one api call makes one
statsd request, maybe the single udp socket is too busy.
We tried to use SO_REUSEPORT on the original nodejs proxy, this enables
us to bind multiple udp sockets on a single port, but nodejs(or libuv) has
disabled this option, and golang just dosen't have a method setsockopt().
Therefore, we made it in C.
