I'm not sure if I understand your setup correctly.

You have 2 clusters that each have two nodes? Is that correct?

There is nothing wrong in the agent log you have attached, I would recommend checking the log of the main OpsCenter process and attaching that as well.

Hi Nick ,

Thanks for the reply ,Its a single cluster with 2 nodes.

opsecenterd.log shows

unable to collect datacenter rack information, connection was refused by other side:10061.

It sounds like you have installed OpsCenter on both of your machines. OpsCenter is meant to be installed on just one machine. Then the agents for OpsCenter are installed on each of the nodes in your cluster.

Can you verify that you have that setup?

Hi Nick,

I installed the setup datastax community software downloaded from the site
http://www.datastax.com/download/community . so by default both nodes got opscenters
how to remove opscenter as it is a single program or any command you can help me with this is appreciated. I am a newbie in cassandra.

If I'll remove the opscenter than how do I install the agent? As agent files are inside the opscenter only .

Is this a windows install? You can stop the OpsCenter service on the machine that has no agents connected through the windows services interface.

yes this is a window install..There are 2 services opscenter_agent and opscenter_community which to stop I checked If I stop opscenter_communtiy then I will not found the UI on my machine and other one is the agent itself.

opscenter_community is the one you want to stop. The UI is only meant to run on one of your machines. You can configure the opscenter_community process on your other machine so that you can access it with a browser from any machine.

The article I linked has the information fo that.

ok that is thank you for the help.

one more help Nick, if I get unavailable exception in opscenterd.log how to remove that.

That indicates that OpsCenter failed to write to to Cassandra because one of your nodes is down. That likely means the replication factor on the OpsCenter keyspace is set to 1. If you update it to 2, then OpsCenter will be able to write with one of your nodes down.

Hi Nick,
still I am not able to access the UI of other machine using this
http://IP of other machine]:8888/opscenter/index.html

opscenterd.log shows

WARN: Unable to collect datacenter, rack information: Failed query to http://*.*.*.17:61621/cluster/datacenter?node_ip=*.*.*.99 : Connection was refused by other side: 10061: No connection could be made because the target machine actively refused it..

mine is *.*.*.17 other one is *.*.*.99
*.*.*.99 machine is server one acting perfectly .

That error in the log means it can not connect to the agent on that machine. It shouldn't affect the UI however.

Did you change the 'interface' property in the opscenter conf file? You will need to update that to be '0.0.0.0' or '<ip of machine>' before you can access the web interface from an external host.
