I have health check warning in vCenter 6.7 health saying:
This issue occurs when the UDP heartbeat message sent by ESX/ESXi hosts is not received by vCenter Server. If vCenter Server does not receive the UDP heartbeat message, it treats the host as not responding. ESX/ESXi hosts send heartbeats every 10 seconds and vCenter Server has a window of 60 seconds to receive the heartbeats. This behavior can be an indication of a congested network between the ESX/ESXi hosts and vCenter Server. Click the Ask VMware link above for more details and a resolution.
I have checked everything, it seems there are no network connectivity issues.
Which log can help me to find which exact host have this "missing UDP heartbeat message" issue?
Tnx.
