我在Linux上安装了1个Cassandra 1.1.2节点,我想确定每个CF在高速缓存中占用的大小,以及每个CF占用多少百分比缓存(用于行缓存和键缓存)Cassandra jconsole的高速缓存节点不可扩展
当我通过jconsole连接到此节点,并且我正在扩展jconsole中的org.apache.cassandra.db节点时,“缓存”节点是无法扩展的,尽管根据于:
http://www.datastax.com/docs/1.1/operations/monitoring#monitoring-and-adjusting-cache-performance
它应该是可扩展的。
此外,nodetool的输出也没有包含属性 关键缓存容量,关键缓存大小和密钥缓存的命中率:
