You have to install mx4j-tools.jar. http://wiki.apache.org/cassandra/Operations#Monitoring_with_MX4J
It's a java tool, so it is usable on both windows and linux. Here is the link to dl mx4j-tool.jar : http://www.java2s.com/Code/JarDownload/mx4j/mx4j-tools-3.0.2.jar.zip unzip it and add it to the path of your cassandra libraries, restart the node where it is installed and you should be ok.
