Question

我试图在Cassandra 3.8上应用Cassandra补丁（https://issues.apache.org/jira/browse/CASSANDRA-11569）。我从https://github.com/apache/cassandra/releases/tag/cassandra-3.8下载了源代码当我尝试使用git apply CASSANDRA-11569.patch -v应用修补程序时出现以下错误

有人可以解释这里可能出现的问题吗？

您无需将该补丁应用于Cassandra 3.8。 3.8已经应用了补丁。

可以使用org.apache.cassandra.metrics:type=Messaging,name=* mbeans从JMX访问，例如使用SJK

> java -jar sjk.jar mx -s localhost:7199 -mg -all -b org.apache.cassandra.metrics:type=Messaging,name=* -f Mean

org.apache.cassandra.metrics:type=Messaging,name=dc2-Latency
1539.538401853893
org.apache.cassandra.metrics:type=Messaging,name=CrossNodeLatency
1539.5348413569534
org.apache.cassandra.metrics:type=Messaging,name=dc1-Latency
1131.752
