Hello,

is there a possibility to get the requests per second generated from pound? I've deactivated logging on my backendservers, so I can't get these value from them ...

With poundctl I can only monitor the active sessions, but not the active requests/minute - right? The logfile grows to fast to get therefrom any infos with grep, wc or such things :(

I'm very interested in any suggestions.

Thanks in advance,
Robert
