For benchmark test of the performance of grpc in node, I wrote a demo. But it's hard to write a dead loop in Node.js to send request to the grpc server. So I wrote this project, use jmeter to send request to test the grpc server run in Node.js.
- Create jar library
mvn package
After run , it will create a jar in target\jmeter4grpc-0.0.1.jar. Copy it to the jmeter's lib/ext directory.
- Create a jmeter project
Open jmeter GUI, right click the Test Plan, and then select the Thread Group.
Then right click the Thread Group menu, created just now, and select Java Request.
Double click the Java Request menu, and select com.whyun.jmeter.GrpcSampler.
Then set the paramters of the java request:
- Check whether the jmeter project is OK
Right click the menu of Java Request , and create a result tree listener:
Click the Start button to start the test, and view the result in View Results Tree:
- Start test
Double click the menu of Thread Group, and input Number of Threads(users), 3 for example. And select Forever for Loop Count.
Save current project, and you will get a project file , let's assume it named grpc_bench.jmx. Then run such command:
`jmeter_dir/bin/jmeter -n -t grpc_bench.jmx -l the_result_log -e -o output_dir/``
