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

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
