"You can find cluster name in ui/Cluster Management Page and admin/System Status pages"
Negative. I can't see it in any place you have mentioned - hence why I posted in this forum. I find it bizarre it can't be found anywhere. The liagent.ini file calls for Cluster name (highlighted in red below)
Interesting this site mentions Cluster name "can be anything you like"

vROps 6.4 - Sample
I've just re-read this and believe there is no Cluster name;
this tag need to be set with the same value for all vROps cluster nodes
What I make of the above statement is to keep the clustername tag consistent per liagent.ini for the vROps Cluster Nodes
[common|filelog]
tags={"vmw_vr_ops_appname":"vROps", "vmw_vr_ops_clustername":"Cluster1", "vmw_vr_ops_clusterrole":"Master", "vmw_vr_ops_nodename":"Node1", "vmw_vr_ops_hostname":"1.2.3.4"}
Below are the details about each of the tags.
vmw_vr_ops_appname:value should be set to "vROps"
vmw_vr_ops_clustername: this tag need to be set with the same value for all vROps cluster nodes
vmw_vr_ops_clusterrole: the tag value to be either the Master, Replica, Data, or Remote Collector based on the node's role in the vROps cluster
vmw_vr_ops_nodename: this tag can be updated
vmw_vr_ops_hostname: typically contains the IP or FQDN of the vRealize Operations Manager node
As the doc states this can be anything
If (in our case) you have more than one vrops cluster this enables you to distinguish between the two when doing your quarries other wise both clusters would return results. Just put a meaningful name in this field that represents your cluster.
If you have a 4 node cluster then put the same value in for each node
