spring - Creating custom Zuul filters -

-

i want implement custom filters zuul proxy. now, know there has been lot of talking subject here , took @ answer provided, examples of filters , spring cloud documentation, went through several times. have tried copy of filters content use, didn't work.

i have eureka server, registering 3 separate services, 1 of them being front door other two, collecting information each of them , retrieving it.

what want able re-route requests zuul receives @ beginning of process, redirect them through particular services, using url parameters determine process should aimed instead of another. have created filter tagged @component annotation, implementing zuulfilter. don't know, how make redirections work, , methods use.

so, question : how can redirect incoming requests different registered services, using url parameters ?

look @ predecorationfilter example matches routes based on url path (ie /myservice). if matches full url sets routehost in ribbon context, otherwise sets serviceid (which use ribbon route). need write similar match on parameter instead.

Listeners to visualise results of load test in JMeter -

-
i want run load test in non-gui mode , save results in .csv file. (i have not modified .properties files, standard information saved) i plan load file , visualise results jmeter’s listeners. which listeners suited purpose? should avoid @ cost, might cause me misinterpret information? (e.g. in view results tree response data empty have - - not saved this. however, there has in fact been response. if saw listener might think there hasn’t been one. since want avoid this, listeners have gain information needed .csv file.) i’d know both jmeter listeners plugins. if running test in non-ui mode ideally should disable listeners in script. use '-l' option store test results .jtl extension. can later open jtl file jmeter. aggregate report or summary report should summarize test results , response time , throughput. if want plot graphs see trends on test duration can use http://jmeter-plugins.org/#/ standard , lib set. i suggest following listeners: response ...
