api - how to meter power(watt) of PC components(cpu,memory,disk,etc) in real time? -

-

as question says ,i want monitor value of power(watts) components consumption .especially value of cpu , memory , disk .

when use aida64，i found in computer/sensor ,there data power consumption . want know how did can these data ?

i have idea ,but not sure best way solve question :

  1. there sensors on motherboard ,we can use values of sensors calculate real-time power.

  2. according different os, have apis can utilization of cpu,memory throughout rate , disk i/o rate . using data ,we can build mode of power consumption pc.if there apis,where can find them ?

  3. maybe hardware manufacturer intel has record value of power in real-time ,they put value special register in hardware .we can value through mapping special memory location .

in opinion ,the second way maybe solution monitor software using .but don't know can api.

whats more ,our aim design os-independent real-time power monitor software. so, if there better solutions question ,i appreciate .

hmmm. wasn't sure if should post comment or answer. answer in negative.

at time, can't create os independent software-based non-intrusive power monitor. non-intrusive, mean not putting special instrumentation on motherboard , other hardware. because power technology being used modern processors in rapid flux, each new generation making significant advances. additionally, amount of power related information available software hardware (via pmu events , like) continually increasing more silicon real estate becomes available. example, believe in current processors, can direct thermal information key parts of processor silicon, , temperature, power , current readings various parts of core , uncore.

the best can abstract top layer of monitor lower layers. top becomes os / hw independent while lower levels need platform dependent.

check out papi apis. note apis appear give world, api set. still has implement what's on other side of api.

now if can own special instrumentation, many (most?) motherboards , other hardware have measurement points (some undocumented) provide thermal, current (and power) information. information important debugging devices , platforms.

yii2 - Yii 2 Running a Cron in the basic template -

-
i have seen instructions on running cron in advanced template, cant figure out how on basic template. have following controller in basic controllers folder. <?php namespace app\controllers; use yii\console\controller; /** * cron controller */ class croncontroller extends controller { public function actionindex() { echo "cron service runnning"; } public function actionmail($to) { echo "sending mail " . $to; } } i have navigated root of application , tried these comands yii cron php yii cron im getting unknown comand "cron" i know old question failed find actual answer this. if @ code yii exec file you'll notice requires /common/config/aliases.php file console/config/main.php. can naturally change these or copy on these advanced template. hope solves problem wanting same thing.

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
