DLQ Center
The DLQ Center is your action inbox for dead-lettered events, everything that failed in a way that won't resolve itself on retry.
How it's organized
Events are grouped by failure class rather than listed one by one, so you're looking at "412 events failing with the same downstream timeout" instead of 412 separate rows. Each group shows a sample reason, how many events are in it, how old the oldest one is, and a severity level (Critical, High, or Low). Filter the whole view by time range: all time, last 24 hours, or last 7 days.
What you can do
Click Inspect on a group to open it in Event Explorer, pre-filtered to exactly those events, so you can look at individual payloads and timelines.
Coming soon Replaying dead-lettered events straight from the dashboard isn't available yet. For now, use the DLQ Center to see what failed and why, then fix the underlying issue in your consumer or producer and let it reprocess normally.
