KR.ADMIN LIST-SILENT-MEMBERS
Lists cluster members suspected to be unresponsive.
Syntax
Section titled “Syntax”KR.ADMIN LIST-SILENT-MEMBERSParameters
Section titled “Parameters”None.
Return Value
Section titled “Return Value”RESP3 array of bulk strings. Each element is the member ID of a member that has been detected as silent. Returns an empty array when all known members are alive.
Behavior
Section titled “Behavior”Returns the IDs of cluster members whose heartbeats have not been observed for longer than the configured
maximum_silent_period. This reflects the local failure-detection state of the responding node, not a cluster-wide
consensus.
Only other RUNNING members are tracked. The local member is excluded from the known-members set and therefore never appears in the result.
A member is marked as silent when its heartbeat has been missing for longer than maximum_silent_period. If a
previously silent member resumes sending heartbeats, it is automatically removed from this list.
Requires cluster initialization.
Errors
Section titled “Errors”| Error | Condition |
|---|---|
ERR cluster has not been initialized yet | The cluster must be initialized first. |
