When trying to view data from various tabs for an edge; Paths, Flows, applications, sources, Destinations, nothing is displayed.
In some cases, VCE is displaying an error message "Connectivity through the Edge Service Gateway is down" and link connectivity also displayed as disconnected.
SD-WAN Edge
One possible reason is something caused the edge to run out of disk space, diagnostic bundles will also fail if there's no free disk space.
Please open a support request to have the VeloCloud support team to investigate.
Once the disk space is cleared up, the missing data will start to populate in the VCO. The VeloCloud support team will be able to further advise on the cause and how to prevent it from happening again.
