CLUSTER COUNT-FAILURE-REPORTS returns how many other primaries currently report the given node as possibly failing, as far as the receiving node has heard. Reports expire after a multiple of cluster-node-timeout, so only recent ones count. Once enough primaries report a node, it is marked as failed and one of its replicas can take over, so the count helps you see why a node is or is not being failed over.

Return value

Case RESP2 RESP3

Compatibility

Same as Redis 7 and Valkey 8. It also answers with cluster mode off, where the only known node is the server itself.
