We use NGINX + Lua [1] to collect real-time diagnostic and performance data from physical machines while they operate. We collect about 150,000 data points (HTTP requests) per second with 2 NGINX servers and 2 Redis servers. We've benchmarked this particular server group up to almost a million req/s before it started to break down (median resp time > 100ms).
