would anyone have any thoughts about the idea of adding an api to obtain the system load average? i ask because i need it for an httpd module i'm writing, and i've now got code for linux, freebsd, os x, sunos, and t64u..
no thoughts, uh.
load average is nice but it seems rather specialized and it doesn't really fit anywhere in apr[-util] that I see. load average is one performance metric; I can see where it might be useful to have a common interface for collecting all sorts of performance metrics. For example, if Apache is being used as a load balancer, you could collect performance state metrics from the servers being load balanced, feed that info back to the apache load balancer (on an HTTP response header field, via a special purpose HTTP POST request or out of band) and use it in your load balancing/routing algorithms.
Errr - mod_backhand?
I just don't see that this has a place in apr or apr-util. Maybe a new subproject, apr-perf?
I don't follow your logic - APR is supposed to make the interface to the system portable. Load average is an interface to the system. Why does it need to "fit"? All it needs is support on enough platforms to be considered common and someone who wants to use it.
Sounds like we have both.
Are you seriously suggesting APR should only support things that are obvious extensions of what it already does?
Cheers,
Ben.
