Description |
Measurement Unit |
Interpretation |
| Sys_cpu_util |
Indicates the percentage of CPU utilized by the Data Domain storage system. |
Percent |
A sudden increase in this value could indicate an unexpected/sporadic spike in the CPU usage of the system. A consistent increase however could indicate a gradual, yet steady erosion of CPU resources, and is hence a cause for concern.
|
| Disk_read_rate |
Indicates the rate at which data is read from the disks of this storage system. |
KB/Sec |
|
| Disk_write_rate |
Indicates the rate at which data is written to the disks of this storage system. |
KB/Sec |
|
| Disk_busy |
Indicates the percentage of time the disks were busy processing requests in this storage system. |
Percent |
|
| Nvram_read_rate |
Indicates the rate at which data is read from the NVRAM of this storage system. |
KB/Sec |
|
| Nvram_write_rate |
Indicates the rate at which data is written to the NVRAM of this storage system. |
KB/Sec |
|
| Data_transmitted |
Indicates the rate at which data is transmitted for replication in this storage system. |
KB/Sec |
The Data Domain replication option leverages its deduplication capability, thus substantially reducing the amount of backup data that needs to be migrated to a remote site. Replication provides rapid local and remote restores from the storage system.
A high value is desired for these measures. |
| Data_received |
Indicates the rate at which data is received for replication by this storage system. |
