Hi,

I did setup a master-master-master(node0-.21, node1-.22, node2-.23) ring replication and it work well.I have check the slave status and all of the node having correct master. I finished install MEM at another server, and i installed MEM agent at node0 , node1, node2.

The master slave relation is like below
node 0 - slave of -> node 1 - slave of -> node 2 - slave of -> node 0

However , i discover that the replication tab at dashboard does not display not display correct replication details(suppose to be ring not tree) , which is shown as below:

And the server details for node0 is also wrong, which it display node2 host and ip address instead of node0 host and ip adress as below:

There is unmonitored master at picture a, .21 which is node0. As you can see in picture b, node0 server details is wrong thus i believe this is what causing the unmonitored master and the replication display as tree instead of ring.

I am wondering what can i do to solve this so that it display correct server details?
Thanks.

Best regards,
Leong
