nacos grpc 如何压测？

[huayangchan]

想对nacos的grpc做压测，用postman尝试通过grpc发起一个ServiceListRequest，
{
"body": {
"type_url": "",
"value": "IntcImhlYWRlcnNcIjp7fSxcIm5hbWVzcGFjZVwiOlwicHVibGljXCIsXCJzZXJ2aWNlTmFtZVwiOlwiXCIsXCJncm91cE5hbWVcIjpcIkRFRkFVTFRfR1JPVVBcIixcInBhZ2VOb1wiOjEsXCJwYWdlU2l6ZVwiOjIxNDc0ODM2NDcsXCJtb2R1bGVcIjpcIm5hbWluZ1wifSI"
},
"metadata": {
"type": "ServiceListRequest",
"clientIp": "127.0.0.1"
}
}
但返回
{
"metadata": {
"headers": {},
"type": "ErrorResponse",
"clientIp": ""
},
"body": {
"type_url": "",
"value": "eyJyZXN1bHRDb2RlIjo1MDAsImVycm9yQ29kZSI6MzAxLCJtZXNzYWdlIjoiQ29ubmVjdGlvbiBpcyB1bnJlZ2lzdGVyZWQuIiwic3VjY2VzcyI6ZmFsc2V9"
}
}
将响应中的value中进行解码得到：
{"resultCode":500,"errorCode":301,"message":"Connection is unregistered.","success":false}，提示连接未注册，InstanceRequest，HealthCheckRequest也有这种我问题，请问在发起这些请求之前是不是还需要发起别的请求注册连接，才能正常响应ServiceListRequest，InstanceRequest这些请求，能指导一下不。

https://nacos.io/docs/latest/guide/admin/nacos2-naming-benchmark/ 使用nacos-client进行压测

如果要自行模拟请求测试的话， 需要先把连接上之后，先发起ConnectionSetupRequest，注册上连接信息，之后再发起正常的请求。期间需要一直保持HealthCheck

[huayangchan]

我用jmeter+nacos-client试了压测。我是继承了jmeter的AbstractJavaSamplerClient，实现了它的runTest方法，在runTest的方法里先创建好GrpcSdkClient，用GrpcSdkClient.start方法建立起链接，new好注册请求，调用request方法发送请求，但是报错

自行创建的GrpcSdkClient的话，需要您自行管理哈，从报错上看是使用grpc的方式出错了。

建议直接创建NacosNamingSerivce和NacosConfigService进行测试

[huayangchan]

换成创建NacosNameingService的进行测试，也还是不行，报错了：com.alibaba.nacos.api.exception.NacosException: Client not connected, current status:STARTING

Client not connected, current status:STARTING

说明客户端没连上服务端， 排查一下配置是否正确，比如host，端口，以及网络本身是否正常。

我把nacos的项目中的nacos-client模块本地打包，放在jmeter里用，服务能注册上，用maven仓中的nacos-client反而不行

[KomachiSion]

那就不清楚了，社区的压测也是拿jmeter构建nacos-client进行的。
