JMeter ile Dağıtık Yük Testi Çalıştırmak

jMeter ile web uygulamalarının yük testini dağıtık olarak gerçekleştirmek mümkündür. Bunun için öncelikle, jMeter testini koşturmak istediğiniz düğümlerde, jMeter'ı sunucu (jmeter-server) olarak çalıştırmalısınız. Örneğimizde, dört ayrı düğümde çalıştırmak yerine, aynı makinada dört jmeter-server prosesi çalıştıracağız. jmeter-server prosesinin belirli bir ağ adresini dinlemesi ve varsayılan port dışında bir portta çalışması için java.rmi.server.hostname ve server_port parametrelerinden yararlanıyoruz:

Düğüm #1

Ardından jmx testini aşağıdaki gibi dağıtık olarak çalıştırabiliriz:

jmeter -n -t google.jmx -R172.17.1.10:4100,172.17.1.10:4200,172.17.1.10:4300,172.17.1.10:4400
