我部署了 hadoop 2 (HDP2),并且想获取我在 ganglia 中的从节点的磁盘 i/o 指标。到目前为止,我没有找到任何相关的指标。
您建议使用或添加到 ganglia 什么指标?
谢谢
您还可以使用此处提供的 Ganglia Python 模块 Disk-stat
As stated by @vishnu: Ganglia Python Module Disk-stat provided here
You can also use gmetric scripts that you would run from cron from here
Finally, you can use collectl and export disk metrics to ganglia, see here
cloudera-manager可以帮助监控集群状态,包括磁盘 I/O
