java - How do I change a remote application's logback log level through http (rest)? -


how change remote application's logback log level through http (rest)? to

@controller public class changelog2controller {      @postmapping("/api/testlog1")     public responsemodel testlogeback(@requestbody loglevelmodel levelmodel) {     ...     } }

something ...

@postmapping("/api/testlog1") public responsemodel testlogeback(@requestbody loglevelmodel levelmodel) {     // change log level root logger     logger rootlogger = (logger) loggerfactory.getlogger(logger.root_logger_name);     rootlogger.setlevel(...);      // change log level specific logger     loggercontext loggercontext = (loggercontext) loggerfactory.getiloggerfactory();     logger specificlogger = loggercontext.getlogger("com.some.specific.package");     specificlogger.setlevel(...); }

... parameter passed setlevel() level.info would, presume, derived loglevelmodel.

note: if looking way dynamically change logging configuration , jmx client (rather http client) suffice logback provides jmx configurator yuou can engage adding following logback.xml: <jmxconfigurator />. exposes jmx mbean can use view , set log levels.

edit 1: based on comments below seems requirement might invoke webapplicationa , somehow enable webapplicationa change log level loggers inside webapplicationb? if so, either

  • webapplicationa has use jmxconfigurator mbean exposed webapplicationb. there examples of java jmx clients here , here. however, in order expose jmxconfigurator must have control on webapplicationb's logback.xml and, if so, perhaps have control on webapplicationb's implementation in case might easier expose simple setloglevel rest endpoint in webapplicationb , let webapplicationa invoke rather playing around java jmx client.

    or

  • webapplicationb has expose changeloglevel rest api (with implementation 1 provided above) webapplicationa can invoke.

the other alternative webapplicationa somehow changes logback.xml used webapplicationb , webapplicationb's logback.xml starts looks ...

<configuration scan="true" scanperiod="30 seconds" >     ... </configuration>

... changes made file on webapplicationb's classpath picked within (for example) 30 seconds. but, since webapplicationb's logback.xml embedded in war (or similar) approach seems awkward , undesireable.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

php - Cannot override Laravel Spark authentication with own implementation -

during login process of laravel spark need request token of remote api. api stores exact same users , passwords laravel spark application. therefore need username , non hashed password of user during authentication process. i thought overriding authenticated method solution problem. in routes/web.php override post /login endpoint , pointing endpoint own logincontroller: <?php namespace app\http\controllers\auth; use illuminate\support\facades\log; use illuminate\http\request; use laravel\spark\http\controllers\auth\logincontroller sparklogincontroller; class logincontroller extends sparklogincontroller { /** * create new login controller instance. * * @return void */ public function __construct() { parent::__construct(); } /** * handle successful authentication attempt. * * @param request $request * @param \illuminate\contracts\auth\authenticatable $user * @return response */ public fu...

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
