How to display performance Metrics information in Opscenter in the Cassandra database

Originally we in (192.168.129.34,192.168.129.35,192.168.129.39 three machine cluster in the correct set up, but in the Opscenter has not received accurate system statistics:

I later studied it because the statistics were sent to this opscenter by the agent of each node, and our Opscenter (on 192.168.129.35) was just a JMX-based management of the system information. So I loaded each node with an agent and turned them on.

The Open method is:

Under the bin of each node's agent directory

Run the./setup 192.168.129.35 192.168.129.xx & To configure the JMX server destination to which you want to send the information

Because we take 192.168.129.35 as the primary server, so the first IP must be 192.168.129.35, the second parameter is the node's own IP address.

For example, to 192.168.129.34 this node for example, we run in the background is

./setup 192.168.129.35 192.168.129.34 &
