Connecting Cloud Innovators: Building Community at .NEXT 2024
Hi @RAMESH BABU, thanks for the suggestion. But even if I left it alone for an hour or so, it was still “No uncaptured traffic flows were detected”. I've been chasing this problem for a long time. Today, I realized that the basic setup might be wrong. I wrote about this setup in the topic: How do I configure physical nic(s) to appear on the Virtual Networks screen?
Today, when I selected Microsegmentation on PC, showed “Precheck Successful” in a short time and I was able to Enable Microsegmentation. The reasons for failure related to ntp was not enabled and the cluster startup failed to come up. Why was PC a little sluggish… that when I first synchronized ntp on PC, time was about 30,000 seconds late (or future, I forget whether it was plus or minus). But, well, thanks to your help, I can test Microsegmentation.
Thx. Cluster start command worked. The PC web management screen also works. But still “AHV Free Memory Minimum 1GB for each Prism Central VM” showed up. nutanix@NTNX-10-10-13-197-A-PCVM:~$ cluster start2020-06-29 20:40:47 INFO zookeeper_session.py:143 cluster is attempting to connect to Zookeeper2020-06-29 20:40:47 INFO cluster:2784 Executing action start on SVMs 10.10.13.197Waiting on 10.10.13.197 (Up, ZeusLeader) to start: SSLTerminator Medusa DynamicRingChanger InsightsDB InsightsDataTransfer Ergon Athena Prism AlertManager Catalog Atlas Uhura SysStatCollector ClusterConfig Mercury APLOSEngine APLOS Lazan Kanon Delphi Metropolis Flow Magneto Search XPlay KarbonUI KarbonCore ClusterHealth NeuronWaiting on 10.10.13.197 (Up, ZeusLeader) to start: SSLTerminator Medusa DynamicRingChanger InsightsDB InsightsDataTransfer Ergon Athena Prism AlertManager Catalog Atlas Uhura SysStatCollector ClusterConfig Mercury APLOSEngine APLOS Lazan Kanon Delphi Metropolis Flow Magneto Search XPlay Kar

@AnishWalia20thank you for your thoughtful response. The node that showed smallest “Memory free” was 56983MB among four nodes. Ntp server(s) referenced by Prism Central was 127.0.0.1, so I fixed it. But still “AHV Free Memory Minimum 1GB for each Prism Central VM” showed up, so I rebooted Prism Central. Then another problem came up… when I look at Prism Central url in my browser, I see "Prism Services have not started yet. Later." and Prism Element's dashboard has "Prism Central – Disconnected". When I logged in to Prism Central with ssh and ran ncli, ncli replied: Connection refuse. What's going on? Prism Central – Disconnectednutanix@NTNX-10-10-13-197-A-PCVM:~$ ncliError: Connection refused (Connection refused)
