Hello,
I am on on a vCloud environement version 5.1.2 with vShield manager also on version 5.1.2-1263988.
I have a lot of error message on System Events on vShield manager interface on most of the Edges (136 Edges deployed).
It happens for both Edge VMs and Edge Gateways. This is the list of messages : (a screenshot is joined also)
| Number | Severity | Code | Message |
|---|---|---|---|
| 1 | Informational | 30041 | vShield Edge Gateway has recovered and now responding to health check. |
| 2 | Informational | 30042 | vShield Edge VM has recovered and now responding to health check. |
| 3 | Critical | 30032 | vShield Edge appliance with vmId : vm-26898 not found in the vCenter inventory |
| 4 | Critical | 30034 | None of the vShield Edge VMs found in serving state. There is a possibility of network disruption. |
| 5 | Major | 30033 | VShield Edge VM not responding to health check. |
I suppose that I may have network issues but what I need to know in order to go further in debug with network team is the exact hleath check test made by vShield Edge to generate these kinf of events, for example : is it from vShield manager to vShield Edge on port TCP 443 ?
Any idea on how health check works or any explanation on these messages is very welcome 
Thanks in advance.

Hello,
I managed to solve this with VMware Support a while ago, it was a know bug on vCNS 5.1.2. You can find this on the resolved issues section of the VMware vCloud Networking and Security 5.1.3 Release Notes : "Both vShield Edges in an HA pair go into Active mode".
For the heartbeat, it uses automatic local IP adresses between the 2 VMs, example :
- Active Edge IP : 169.254.1.1
- Backup Edge IP : 169.254.1.2
- Heartbeat ports : UDP 694 and 3780
- Heartbeat default timeout : 6 seconds
- Config sync : TCP 873
- Sync interval : 10 seconds
I hope this helps someone else 
Regards,
