Abstract
End-to-end performance measurement is fundamental to building
high-performance Internet services. While many Internet services
often operate using HTTP over SSL/TLS, current monitors are
limited to plaintext HTTP services. This paper presents
sMonitor, a non-intrusive server-side end-to-end performance
monitor that can monitor HTTPS services. The monitor passively
collects live packet traces from a server site. It then uses a
size-based analysis method on HTTP requests to infer
characteristics of client accesses and measures client-perceived
pageview response time in real time. We designed and implemented
a prototype of sMonitor. Preliminary evaluations show
measurement error of less than 5%.
