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. |
