From 7397526d0c80251b3006b1b45af754f5ad7adb76 Mon Sep 17 00:00:00 2001 From: Nenad Merdanovic Date: Mon, 3 Oct 2016 04:57:37 +0200 Subject: [PATCH 05/26] MINOR: Add fe_req_rate sample fetch The fe_req_rate is similar to fe_sess_rate, but fetches the number of HTTP requests per second instead of connections/sessions per second.
