频繁的 grpc discovery.Discovery、callChaincode、QueryChaincodeDefinition 日志记录在 Hyperledger Fabric Peer 中

Question

一个具有两个对等点和 3 个订购者的 hyperldger 结构网络，链码已安装在两个对等点中，一切正常，但我在对等点上看到以下日志，有人可以告诉发生了什么吗？

Peer-1 显示大量不断出现的频繁 discovery.Discovery 日志。

Peer-2 还显示大量 callChaincode、QueryChaincodeDefinition 日志，但没有 Txns 到来，链上代码没有被调用

Answer 1

不用担心。这只是同行保持 MSP 更新所需的后台工作。我相信一个是锚点，而另一个则试图以一定的时间间隔进行更新。你可以调整日志级别来调试，这对于学习 HLF 来说已经足够了。
