I have tried to connect to it via jconsole. Apart from that I have seen people of this list use Ganglia to collect metrics or just dump to a file. To start off you could easily use FileContext (dumping metrics to file). Check out the metrics config file (hadoop-metrics.properties) under conf directory. Specify file name and period to monitor the metrics. Thanks, Lohit

Could anyone that has any experience on the topic share some info. What is the URL to use to connect to the MBeanServer ? Is it done through rmi, or only through jvm ? Any help is highly appreciated. Please cc me as i am not a member of the list. Regards: Ivan
