This post will walk you through the steps needed to capture the incoming/outgoiing traffic on Tier0 gateway uplink level. The result will be a PCAP file that can be imported into a packet analyzer such as Wireshark for further troubleshooting and analysis.
I came into a scenario recently where we need to decommission a cluster from a provider PVDC where that cluster also contains workloads already provisioned by the customer through the VCD tenant portal. In order to do so, we need to migrate a bunch of workloads for an organization from the orgVDC under workload cluster 1 knowing that both workload cluster 1 and cluster 2 are part of an elastic PVDC spanning both clusters. There may be other ways to do the migration but I want to share my simple procedure that I followed which may help others in case the hit the same use case. Always keep it simple!
