This is a java project (maven) to create a gRPC client with JMeter samplers to enable stress testing with JMeter
Build with maven and copy the generated whatalokation-grpc-client-all.jar (target directory) to JMeter lib/ext folder (e.g. /usr/local/apache-jmeter-3.1/lib/ext/) so that the samplers are in the class path
launch JMeter and you should be able to see the classes in the "java request" samplers.
