Many compared with `pulls`: changes arrive from several sides at once. | | `relay.treeForwards` | `tree_forwards_total` | Changes passed on along writers' trees ([`peers.md`](peers.md)): a sync message per child, at once, instead of an announcement and a pull. | +| `relay.treeFromOthers` | `tree_from_others_total` | Sync messages along a writer's tree, carrying changes, from a peer other than our parent in it: a change sent twice, or the parent and the child working out the tree differently. Near zero while the trees work; against `treeForwards` swarm-wide, the share of passes that went to the wrong child. | +| `relay.treeMissed` | `tree_missed_total` | Changes of writers in whose trees this node has a parent that came another way (pulled, with an answer, in a delta): the tree didn't bring them, or not first. Some while members come and go; growing with every write, a tree that doesn't work here. | | `relay.blobRequestsDropped` | `blob_requests_dropped_total` | Blob requests not answered because too many were being answered; the requester asks again or asks another peer. Also logged as a warning, at most once a minute with the count. | ## Topology |
