- From: Nenad Merdanovic <nmerdan@anine.io>
- 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.
-
- Signed-off-by: Nenad Merdanovic <nmerdan@anine.io>
- (cherry picked from commit ad9a7e9770e673a70fb56ab95be18bf88666d92a)
