这听起来像是一个基本问题-但我对所有文献感到困惑。
我在3.11.x上有一个3节点的Cassandra群集,其中有1个种子节点。
我们正在使用位于群集外部的单个线程客户端在此设置中测试蛮力写入吞吐量。
有了nodetool和cqsl,我将如何切实评估以下内容:
Multiple commands produce '/Users/mohsenkhodadadzadeh/Library/Developer/Xcode/DerivedData/walk-fcnteanemrfigmfaalqkvwigvwqc/Build/Intermediates.noindex/walk.build/Debug-iphonesimulator/walk.build/Objects-normal/x86_64/WalkEntity+CoreDataProperties.o':
1) Target 'walk' (project 'walk') has compile command for Swift source files
2) Target 'walk' (project 'walk') has compile command for Swift source files

2) Target 'walk' (project 'walk') has compile command for Swift source files
答案 0 :(得分:0)
最好的方法是使用Opennms或Zabbix之类的工具监视Cassandra的JMX端口,并比较指标(如Mutation,compatcion等)(此处有数百个指标): https://docs.datastax.com/en/cassandra/3.0/cassandra/operations/opsMonitoring.html
