The DogStatsD source must have full support for Origin Detection, which includes:
container ID extension (e.g., counter:1|c|c:acdea168264a08f9aaca0dfc82ff3551418dfd22d02b713142a6843caa2f61bf for resolved container IDs, or counter:1|c|c:in-1273114 for container cgroup controller inode)
entity ID tag (e.g., counter:1|c|#dd.internal.entity_id:7e87a71f-5f07-4d4f-8560-d7dbe666c66b)
UDS-based peer socket credentials (uses SO_PEERCRED to get the process ID of the sending client, which is then resolved to the container ID it belongs to)
External Data extension (stringified list of additional origin attributes, e.g. counter:1|c|e:it-false,cn-nginx,pu-3413883c-ac60-44ab-96e0-9e52e4e173e2)
