   Is Cassandra/DSE properly running on your local machine? If so, make sure you're using whatever IP you've configured for rpc_address in cassandra.yaml.

   I executed the "dse cassandra -t" and it works fine.
   After that for getting the display I executed the command "opscenter -f" from opscenter 2.1 directory.

   For starting the agent I executed "bin/opscenter-agent -f". Server agent gets connected.

   But than while going to browser "http://10.3.248.46:8888" where 10.3.248.46 is the ip address of my server; it asks for the cluster hosts where I entered 10.3.248.46 and presses add cluster it gives error. I guess I am missing configuration somwhere.

   Logs I already gave in my earlier post.

   rpc_address I have set to 10.3.248.46. Do I need to reboot the server after changing??

   Pl. help!!

   If you've changed rpc_address, you will have to restart DSE for it to take effect. Let us know if that doesn't work.

   I restarted DSE and than I tried to login to browser "http://10.3.248.46:8888" I get following welcome page:

   Welcome to DataStax OpsCenter!
   To get started, fill in your existing cluster's information below.Help
   Cluster Hosts/IPs (newline delimited)

   JMX Port

   Thrift Port

   Add credentials (optional)
   Add Cluster

   When I enter Cluster Hosts/Ip as 10.3.248.46 and then click add server I get Error saying "Error creating cluster: Unable to connect to cluster"

   Are you able to 'telnet 10.3.248.46 9160'? That will verify whether or not DSE is properly listening on the standard thrift port on that interface.

   Can you also change the log level in opscenterd.conf from INFO to DEBUG? You can do this via the level property in the [logging] section. Once you change that, you'll need to restart the opscenter process and try adding your cluster again.

   When i did the telnet I get the following result:

   telnet 10.3.248.46 19160
   Trying 10.3.248.46...
   Connected to 10.3.248.46.
   Escape character is '^]'.

   I changed the log level as well to DEBUG and than restarted it. Again the same error as previous.

   Hi Mbulman...its working now...there was a problem with thrift port...it was supposed to be 19160 but by default it was coming as 9160...I modified it to 19160 and it starts working....Thanks a lot for all your help. :)
