ClusterNode is a datatype for a node in the a LogScale cluster.

This datatype is used by the datatype, Cluster, which is used by the cluster() query field. It's also used by the Segment, which is used by the segment() query.

ParameterTypeRequiredDefaultStabilityAvailabilityDescription
assignedTasksNodeTaskEnumyes Short-Term The datatype for this is an enumerated list of values. See NodeTaskEnum.
bootedAtDateTimeyes Long-Term The date and time, in the ISO-8601 instant format (e.g., 2022-12-03T10:15:30.00Z), when the host was booted.
canBeSafelyUnregisteredBooleanyes Long-Term Whether the node can be safely unregistered.
clusterInfoAgeSecondsFloatyes Long-Term The age of the cluster information in seconds.
consideredAliveUntilDateTime  Short-Term The date and time, in the ISO-8601 instant format (e.g., 2022-12-03T10:15:30.00Z), for when the node is to be considered alive or active.
currentSizeFloatyes Long-Term The size in gigabytes of data currently on this node.
evictionStatusEvictionStatusyes Long-Term The data describing the status of eviction. See EvictionStatus.
freeOnPrimaryFloatyes Long-Term The size in gigabytes of the free space on this node of the primary storage location.
freeOnSecondaryFloatyes Long-Term The size in gigabytes of the free space on this node of the secondary storage location. Zero if no secondary is configured.
hasDigestRoleBooleanyes Long-Term Whether the node can process Kafka partitions.
hasStorageRoleBooleanyes Long-Term Whether the node has local segment storage.
humioVersionStringyes Long-Term The version of LogScale used by the cluster node.
idIntyes Long-Term The unique identifier of the cluster node.
inboundSegmentSizeFloatyes Long-Term The size in gigabytes of data this node needs to receive.
isAvailableBooleanyes Long-Term Whether the node is considered up or down by the cluster coordinated. This is based on the lastHeartbeat field.
isBeingEvictedBoolean  Long-Term Whether the node is marked for eviction. The Falcon LogScale cluster will start to move segments, digesters and queries it contains.
lastHeartbeatDateTimeyes Long-Term The last time, in the ISO-8601 instant format (e.g., 2022-12-03T10:15:30.00Z), a heartbeat was received from the node.
nameStringyes Long-Term The name of the cluster node.

primarySizeFloatyes Long-Term The size in gigabytes of the data currently on this node that are in the primary storage location.
reasonsNodeCannotBeSafelyUnregisteredReasonsNodeCannotBeSafelyUnregisteredyes Long-Term The reasons the node cannot be safely unregistered. See ReasonsNodeCannotBeSafelyUnregistered.
secondarySizeFloatyes Long-Term The size in gigabytes of the data currently on this node that are in the secondary storage location. Zero (i.e., 0) if no secondary is configured.
solitarySegmentSizeFloatyes Long-Term The size in gigabytes of data that only exists on this node - i.e. only one replica exists in the cluster.
supportedTasksNodeTaskEnumyes Short-Term A list of supported tasks. See NodeTaskEnum.
targetSizeFloatyes Long-Term The size in gigabytes of data once the node has received the data allocated to it.
timeSinceBootedLongyes Long-Term The time since the last boot.
timeSinceLastHeartbeatLongyes Long-Term The time since a heartbeat was received from the node.
totalSizeOfPrimaryFloatyes Long-Term The total size in gigabytes of the primary storage location on this node.
totalSizeOfSecondaryFloatyes Long-Term The total size in gigabytes of the secondary storage location on this node. Zero if no secondary is configured.
