Subject Re: monitor cassandra 1.1.6 with MX4J
Date Tue, 13 Nov 2012 07:43:00 GMT
Thank Michael.

Adding the config to the file I can configure the port and address to use
with mx4j.

Wei Zhu, you are right. If you only add the mx4j-tool to the classpath
cassandra enable mx4j by default using the default port 8081.
