ironmesh-peers

IronMesh peer detail

Show every known peer with full metrics, including retry breakdown by reason and session rekey history. Useful for diagnosing a flaky peer.

When to use

• After ironmesh-status shows a peer offline or with a high retry count
• When tracking down why bandwidth to a specific peer is low
• Before a rekey investigation — confirm session_rekey_count is what you expect

How to run
