Cassandra adding node : opscenter agent not connected

Question

I am using Datastax community edition in two windows PCs(64 bit and 32 bit respectively). After setting the initial configuration in cassandra.yaml, in the Opscenter web interface its showing that "1 of 2 agents connected" and recommending to install opscenter agent.
Node 1(ip: X.X.X.X) Configuration:
Cluster name : Test Center
seeds : Y.Y.Y.Y
listen address :
rpc_address : 0.0.0.0
endpoint_snitch: SimpleSnitch
num_tokens: 256
Node 2(ip: Y.Y.Y.Y) Configuration:
Cluster name : Test Center
seeds : X.X.X.X
listen address :
rpc_address : 0.0.0.0
endpoint_snitch: SimpleSnitch
num_tokens: 256
By default auto_bootstrap attribute was absent so I didn't add that and as per instruction I first stopped the services and after changing this setting I started them.
Q1. Any settings I'm missing ?
Thanks for kindly help.
Edited : From X.X.X.X node, the status of Y.Y.Y.Y node

Answer 1

You need to configure the datastax-agents so they know what machine OpsCenter is running on.

To do this you will need to edit the following line in address.yaml located in C:\Program Files\DataStax Community\opscenter\agent\conf.

stomp_interface:

If X.X.X.X is your opscenterd machine:

set stomp_interface: X.X.X.X for all nodes.

Answer 2

1. you have made a mistake with the seeds. If these 2 nodes are part of the same cluster (and you've indicated that they both have same name "Test Center", then the seeds should be the same, not different. Set seeds: Y.Y.Y.Y in both nodes. Shutdown both nodes. Start node 1, after it is up then start Node 2. Node 2 will get its settings from the seed (Node 1).

2. listen_address: shouldn't be blank. set it to the ip address of the interface that the node will be listening on. I am assuming these are physical machines.
