NetApp Cluster-Mode Disk Performance

Table: NetApp Cluster-Mode Disk Performance

Metric	Description
Disk Busy	Time base for the disk-busy calculation.
Consistency Point Read Blocks	Number of blocks transferred for consistency point read operations per second.
Consistency Point Read Blocks Avg	Average number of blocks transferred in each consistency point (CP) read operation during a CP check.
Consistency Point Latency	Average latency per block in microseconds for consistency point read operations.
Consistency Point Read	Number of disk read operations initiated each second for consistency point processing.
Disk Busy %	Percentage of time there was at least one outstanding request to the disk.

Guaranteed Read	Number of disk read operations initiated each second for RAID reconstruct or scrubbing activities.
Guaranteed Write Blocks	Number of blocks transferred for guaranteed write operations per second.
Guaranteed Write Blocks Avg	Average number of blocks transferred in each guaranteed write operation.
Guaranteed Write Latency	Average latency per block in microseconds for guaranteed write operations.
Guaranteed Write	Number of write read operations initiated each second for RAID reconstruct or scrubbing activities.
Blocks Skipped IOPS	Number of blocks skipped in skip-mask write operations per second.
# Disk IOPS	Total number of disk operations per second involving initiated data transfer.
