load testing - PerfMon plugin throwing error (with use of variables) in JMeter distributed Mode -

-

i have implemented perfmon metrics collector (listeners) in jmeter scripts. these listeners have host , port fields. have defined variables these in test plan , using them in listeners.

i tested these scripts in non-distributed mode , worked perfectly.

sample screenshot

now, converted scripts distributed mode. works fine except perfmon listeners throw following error message:

2016/02/29 09:06:35 error - kg.apc.jmeter.perfmon.perfmoncollector: perfmon plugin error: java.net.connectexception: connect: address invalid on local machine, or port not valid on remote machine

this error seemed related invalid value (may these listeners not handle special characters {} $ in distributed mode!!). so, removed variables host/port , instead used hard coded values , worked fine.

so apparently, these listeners not work in distributed mode (if used variables).

is there workaround issue have plenty of perfmon listeners in setup , manually changing them tiresome job.

go jmeter properties instead of jmeter variables, like:

  • substitute ${host} ${__p(host,)}
  • substitute ${port} ${__p(port,)}

  • pass host , port properties values on jmeter master side like:

    jmeter -ghost=target_hostname_or_ip -gport=target_port -s -n -t ....

  • you can have different values on different slaves, in case specify properties in user.properties file (it's located under /bin folder of jmeter installation) like:

    host=10.20.30.40 port=1234

    remember restart jmeter after editing configuration file.

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
