php - Logs for an API in symfony 1.4 -

-

i working on rest api in symfony 1.4

i log comes in , out of "api" application. in log/api folder, keep track of api calls in various files. call mymodule/myaction, have 3 files:

  • mymodule_myaction_rq.log requests
  • mymodule_myaction_rs.log responses
  • mymodule_myaction_error.log error responses

i know how manually, adding code @ beginning , @ end of each action. here how go:

class myactions extends sfactions {    /**  * log function  */ private static function customlog($message, $seed, $url, $content, $type) {     $file =  sprintf('%s/%s_%s.log', sfconfig::get('sf_log_dir', "no_log_dir")."/api", $message, $type);     $logger = new sffilelogger(                 new sfeventdispatcher(),                  array('file'=> $file)             );      $logger->log( sprintf("#%s# (%s) %s ", $seed, $url, $content),                     0,                      "info"     ); }  /**   * executes index action   *   * @param sfrequest $request request object   */   public function executeindex(sfwebrequest $request)   {     try {                    $json_msg = $request->getcontent();         // log !!!         $seed = rand();         $current_uri = "http://$_server[http_host]$_server[request_uri]";         self::customlog("availability", $seed, $current_uri, $json_msg, 'rq');                      // api logic set $response_msg                     // ...                      $this->response_msg = $response_msg;          // log !!!         self::customlog("mymodule_index", $seed, $current_uri, $response_msg, 'rs');      }     catch(exception $e)     {         // throw $e;         $this->settemplate("error");         $this->error = $e;          // log !!!         self::customlog("mymodule_index", $seed, $current_uri, $e->getcode().":".$e->getmessage(), 'error');     }    }

here example of logged information:

 mymodule_index_rq.log:  apr 25 11:49:31 symfony [emerg] #958824120# (http://host.local/api_dev.php/users/1/index {"price_km":0.66,"reservation_type":3, "position":{"long":2.139015,"lat":41.37947}}   apr 25 11:56:27 symfony [emerg] #512729287# (http://host.local/api_dev.php/users/1/index {"price_km":0.66,"reservation_type":3,"position":{"long":2.161576,"lat":41.396896}}  mymodule_index_rs.log: apr 25 11:49:32 symfony [emerg] #958824120# (http://host.local/api_dev.php/users/1/index) {"id_availability":539,"alternatives":[{"id_alternative":1,"duration":9,"reservation_type":3,"distance":3.5,"price":1.62,"original_price":2.31}]}  apr 25 11:56:27 symfony [emerg] #512729287# (http://host.local/api_dev.php/users/1/index) {"id_availability":540}   mymodule_index_error.log:  apr 25 11:38:20 symfony [emerg] #1059359810# (http://host.local/api_dev.php/users/1/index) 4205:position out of service area

now tedious...

i understand knowledge of symfony internals, achieve nicely (dryly). here come questions:

  • events may way done. right ? if so, events should use ? how put ?
  • with $request->getcontent(), able content of message sent me. how can pick response content ? (as content of view known after action over, not can done "as usual").
  • well, filters possibly way achieve logging functionnality ?
  • maybe problem sooo standard set in config file ? silly ? or module may doing ?

this level of symfony internals still quite new me, hint, piece of code... welcome !

well, seems filters way it... first, buid filter class in lib folder of app:

<?php class logfilter extends sffilter{   public function execute($filterchain){        $request = $this->context->getrequest();       $response = $this->context->getresponse();        $seed = rand();       $this->customlog($seed, $request->getcontent(), 'rq');        $filterchain->execute($filterchain);            $this->customlog($seed, $response->getcontent(), 'rs');   }   /**  * log  *  @param integer $seed: random number identical across request , response.  *  @param string $content: content of message logged  *  @param type: type of message (rq = request, rs = response)  */ private function customlog($seed, $content, $type) {     // current action information     $modulename = $this->context->getmodulename();     $actionname = $this->context->getactionname();     $message = $modulename."-".$actionname;     $url = "http://$_server[http_host]$_server[request_uri]";      $file =  sprintf('%s/%s-%s.log', sfconfig::get('sf_log_dir', "no_log_dir")."/api-in", $message, $type);     $logger = new sffilelogger(                 new sfeventdispatcher(),                  array('file'=> $file)             );      $logger->log( sprintf("#%s# (%s) %s ", $seed, $url, $content),                     0,                      "info"     ); }  }

register filter in filters.yml configuration file (in app config folder), between security , cache:

rendering: ~ security:  ~  # insert own filters here mycustomfilter:     class: logfilter  cache:     ~ execution: ~

and... !

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2

i need place custom knob image shadow uislider. far have image of 38x38, of there region defines shadow of knob. now while using image, when slide knob extreme ends actual knob not able cover end points, hence end points visible under transparent region of knob image this code using customize uislider uiimage *slidebtimg = [uiimage imagenamed:sliderknobimg]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatenormal]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatehighlighted]; how can implement custom knob shadow beneath it, covering end points?? look inside uislider.h , there methods let customize slider knob , track needed.
