I'm not able to monitor my Cassandra 1.0 cluster with the free version of opscenter 1.3. It seems that OpsCenter can't find any node even if it knows the cluster. it displays:
My Cluster (Cassandra )
I have got 2 nodes with IPs x and y. I installed OpsCenter on the node x. My cluster is correctly installed :
nodetool -h localhost ring ->
Address DC Rack Status State Load Owns Token
x datacenter1 rack1 Up Normal 7.87 MB 80.00% 0
y datacenter1 rack1 Up Normal 1.43 MB 20.00% ....
I configured this 2 nodes with :
x (cassandra.yaml) ->
cluster_name: My Cluster
y (cassandra.yaml) ->
cluster_name: my cluster
x (opscenterd.conf) ->
interface = myaddresswhichdoesntmatter.com
The rest of the configuration is the default one.
There is one more weird thing. When I decommission or removeToken of the y node, Opscenter immediatly displays the node x as being up:
Any Ideas? Did I do something wrong?
Should you need further informations, please let me know.
