clusterStats

The clusterStats object contains statistical data for a cluster. Many of the volume-related statistics contained in the object are averaged for all volumes in the cluster. You can use the GetClusterStats method to retrieve this information for a cluster.

Object members

This object contains the following members:

Name Description Calculation Type
actualIOPS Current actual IOPS for the entire cluster in the last 500 milliseconds. Point in time integer
averageIOPSize Average size in bytes of recent I/O to the cluster in the last 500 milliseconds. Point in time integer
clientQueueDepth The number of outstanding read and write operations to the cluster. N/A integer
clusterUtilization The cluster capacity being utilized. N/A float
latencyUSec The average time, in microseconds, to complete operations to a cluster in the last 500 milliseconds. Point in time integer
normalizedIOPS Average number of IOPS for the entire cluster in the last 500 milliseconds. Point in time integer
readBytes The total cumulative bytes read from the cluster since the creation of the cluster. Monotonically increasing integer
readBytesLastSample The total number of bytes read from the cluster during the last sample period. Point in time integer
readLatencyUSec The average time, in microseconds, to complete read operations to the cluster in the last 500 milliseconds. Point in time integer
readLatencyUSecTotal The total time spent performing read operations since the creation of the cluster. Monotonically increasing integer
readOps The total cumulative read operations to the cluster since the creation of the cluster. Monotonically increasing integer
readOpsLastSample The total number of read operations during the last sample period. Point in time integer
samplePeriodMSec The length of the sample period, in milliseconds. N/A integer
servicesCount The number of services running on the cluster. If equal to the servicesTotal, this indicates that valid statistics were collected from all nodes. Point in time integer

timestamp The current time in UTC+0 format. N/A ISO 8601 date string
unalignedReads The total cumulative unaligned read operations to a cluster since the creation of the cluster. Monotonically increasing integer
unalignedWrites The total cumulative unaligned write operations to a cluster since the creation of the cluster. Monotonically increasing integer
writeBytes The total cumulative bytes written to the cluster since the creation of the cluster. Monotonically increasing integer
writeBytesLastSample The total number of bytes written to the cluster during the last sample period. Monotonically increasing integer
writeLatencyUSec The average time, in microseconds, to complete write operations to a cluster in the last 500 milliseconds. Point in time integer
writeLatencyUSecTotal The total time spent performing write operations since the creation of the cluster. Monotonically increasing integer
writeOps The total cumulative write operations to the cluster since the creation of the cluster. Monotonically increasing integer
writeOpsLastSample The total number of write operations during the last sample period. Point in time integer
