JMeter load-testing: ClassNotFoundException: com.blazemeter.jmeter.threads.concurrency.ConcurrencyThreadGroup

Question

J'essaie des tests de charge non-GUI et distribués JMeter.

Avant d'être distribué, je l'ai testé localement. J'ai installé JMeter sur mon ordinateur portable et mis en place un plan de test ciblant le système testé. J'ai installé le gestionnaire de plugin et j'installe le plugin de threads simultanés. J'ai trouvé mon fichier JMX correct et fonctionnel, j'ai donc décidé de déployer le paramètre distribué.

Je configure trois machines pour la génération de charge: load-1, load-2 et load-3. J'ai installé JMeter comme suit: apt update ; apt upgrade sur tous apt install jmeter sur tous les ont copié les fichiers JAR situés dans/usr/share/jmeter/lib/ext de mon ordinateur portable à tous, dans le même répertoire:

jmeter-plugins-casutg-2.1.jar 
jmeter-plugins-cmn-jmeter-0.3.jar 
jmeter-plugins-manager-0.11.jar 

j'ai commencé le serveur JMeter sur deux d'entre eux comme suit:

export JMETER_HOME=/usr ; $JMETER_HOME/bin/jmeter-server -Djava.rmi.server.hostname=207.112.137.21 
export JMETER_HOME=/usr ; $JMETER_HOME/bin/jmeter-server -Djava.rmi.server.hostname=207.112.137.22 

J'utilise le troisième pour commencer les tests distribués comme suit:

jmeter -n -t ~/JMeter_API_TestPlan.jmx -R207.112.137.21,207.112.137.22 

Le paramètre distrubuted semble démarrer correctement, mais le début de fil échouent probablement à cause d'une classe pas trouvé:

java.lang.ClassNotFoundException: com.blazemeter.jmeter.threads.concurrency.ConcurrencyThreadGroup (pas responsable de la sécurité : Chargeur de classe RMI désactivé)

AI manque un JAR ou un paramètre de configuration?

Le jmeter.log montre les éléments suivants:

Je cours Ubuntu 16.04.2 LTS

Answer 1

1. jmeter-plugins-cmn-jmeter-0.3.jar devrait aller dans le dossier "lib", pas "lib/ext"
2. Vous utilisez JMeter 2.11 qui a plus de 3+ ans, je vous recommande de passer à JMeter 3.2 (ou plus tard) en le téléchargeant manuellement à partir de JMeter downloads page. les dépôts Ubuntu semblent contenir très obsolète la version JMeter
3. Pour éviter tout problème avec les plugins installation manuelle je suggère d'installer les mêmes plugins définis sur l'hôte maître et tous les esclaves en utilisant JMeter Plugins Manager
