System Load Tool
The System Load tool is used to view and monitor the system load statistics over a specified time period. The time period is controlled with a selectable date range in the lower left-hand-side of the screen. The selectable date range for the load is the last 24 hours, the last 7 days, and the last 30 days. The load chart is divided into three general areas: ideal, warning, and alarm:
- Ideal area: If the system load is primarily in this area, it is within guidelines and thus will result in optimum backup performance.
- Warning area: There are times when the load level will largely remain in the ideal area but will occasionally spike into the warning area, and this is to be expected depending upon backup schedules or daily operations that are taking place on the appliance. However, if the load level stays in the warning area for extended periods of time, it is indicative of a high load that could lead to longer backup times if a DPU or vaulting times if a DPV.
- Alarm area: The appliance's system load can occasionally spike into the alarm area. If it does, monitor backup times periodically and check to see that the load level decreases out of the alarm area. If the load remains in the alarm area and does not decrease over a period of days or weeks, consider adding an additional appliance. If a DPU, register some of the clients and assigning backups to another DPU to lessen the load on this DPU. If a DPV, reassign some of the DPUs to another DPV for vaulting.
