I have 2 node Cassandra cluster with datastax-agent up and running(one seed node) also nodetool status showing healthy.
In the 3 node I have opscenter install and the UI is loading fine with a blank screen, when I saw the var log it's complaining 'NO cassandra connection available for hostlist with a invalid unsupported version'(paster the log details message below). Any help is highly appreciated
2017-02-25 06:33:06+0000 [CLUSTER_NAME] ERROR: Control connection failed to connect, shutting down Cluster: ('Unable to connect to any servers', {'SEED-IP': })
2017-02-25 06:33:06+0000 [CLUSTER_NAME] WARN: No cassandra connection available for hostlist ['SEED-IP'] . Retrying.
I was using an old version of opscenter which was not matching the version of dse. Here is the map for your refference.

For my 6 node cluster, I am unable to cqlsh <ip> to the cluster. It gives me :
Connection error: ('Unable to connect to any servers', {'192.168.19.2': ProtocolError("cql_version '3.3.1' is not supported by remote (w/ native protocol). Supported versions: [u'3.4.4']",)})
But, I checked nodetool status, all my nodes are up and running. Also, I am able to contact the cluster via client.
For the cassandra.yaml on each node, I set the following parameters:
listen_address: node's ip
broadcast_address: node's ip
rpc_address: node's ip
broadcast_address: left blank
seed node: same two ips in each nodes
What seems to be the issue?
Update:
I am able to cqlsh from other nodes but not from the first nodes. I can observe that while working on the first node, I somehow messed up with its cqlsh version. Is it possible to change it?
Connection error: ('Unable to connect to any servers',
{'192.168.19.2': ProtocolError("cql_version '3.3.1' is not supported

You do have different versions of cassandra installed or using the wrong driver. You want to upgrade to your drivers for connecting to your cluster as 3.4 seems to be a 3.10.x cluster while your driver only supports 3.0.x.
I am facing issue when I try to connect opscenter-agent to opscenter . In UI when we put any node ip it's shows Error creating cluster: Timeout while adding cluster. Please check the log for details on the problem.
In opscenter log I getting below error

Im tring t build up an Hawkular Server in Windows 7 - unfortunately this server works with a Cassandra DB - ive installed the newest version and in the starting process of Hawkular I got following error:

Cassandra DB is online and I can connect to localhost:9160 with the Cassandra CQL Shell - but not the hawkular server - have I forgotten something?
From the log, the port Hawkular is trying to use is 9042. Make sure of this setting in your cassandra.yaml
start_native_transport: true
native_transport_port: 9042
The port you are using (9160) is thrift port.
I can only take a stab in the dark with such limited information.
However you said you connected to localhost:9160. In the log it mentions "127.0.0.1:9042".
hi everybody im using OpsCenter 5.2.0 and agent connected to opscenter
bout no Disks in Dashboard I have error on datastax-agent log
ERROR [os-metrics-7] 2015-08-23 21:00:37,095 Short os-stats collector failed: Process failed: df --print-type --no-sync --block-size=1G --local
I am unable to connect to to the cassandra. By this I mean that when I try cassandra-CLI, or pycassaShell I get the following error:
Exception connecting to localhost/9160. Reason: Connection refused.
I have tried using a few non-defaul ports but to no joy.
I am running cassandra version 1.0.7
I have tried bounding the service, using restart, stop, start, and force-restart.
Run jps command under root user and kill CassandraDaemon if you will see it. After this you will start Cassandra again.
My problem was cassandra was not even starting. Solution was to start Cassandra!
I had the same issue in cassandra, After rename var/lib/cassandra/data to var/lib/cassandra/data1 then cassandra is working fine, If cassandra alloted maximum memory is full then it will throw connection refuse exception
