We have initialized a new 3 node cluster today. with couchbase version 4.6.3 and I could see the graphs which we refer for the ongoing stats are not plotted regularly. Graphs are broken in the middle or not continuous.
Please let me know if there is any problem and any required logs. I have attached the screenshot of the GUI here.
This happens when the cluster manager (ns_server) couldn’t fetch statistics for that period.
This commonly happens when the system is heavily loaded or there are network or scheduling issues. Are you running on a virtualised platform?
Yes, couchbase nodes are VMs. and each VM is 8vCPU,32GB RAM configured. This node used only as a DB node and when broken graphs was observed there was 2 or 3 ops was happening on couchbase side which you can observe from the previously attached graph.
