This of course reduces the time period to see historical data. You can also choose to increase the reduction factor to be able to store more data for a longer time. | This of course reduces the time period to see historical data.

The time printed in parentheses represents the worst-case graph resolution based on the chosen resolution and reduction factor. | The time printed in parentheses represents the worst-case graph resolution based on the chosen resolution and reduction factor. | ||
Note: Regardless of these settings, the graph values are always converted to represent a value per second (when applicable). For example, the packets per second for IP addresses will always be a value literally per second even if the resolution is larger or smaller than one second. | Note: Regardless of these settings, the graph values are always converted to represent a value per second (when applicable).

The shown value is scaled to match this view. Especially with sub-second resolution this might be misleading. | The shown value is scaled to match this view. Especially with sub-second resolution this might be misleading. | ||
For instance, if there is a network element sending one packet per second and the resolution is set to 100 millisecond, the value might be shown as 10 packets per second as each sample point is scaled to represent an value per second. | For instance, if there is a network element sending one packet per second and the resolution is set to 100 millisecond, the value might be shown as 10 packets per second as each sample point is scaled to represent an value per second. | ||
For a detailed investigation it is recommended to select a specific time interval since the total packet counters shown in all statistics are unscaled and represent the actual values. | For a detailed investigation it is recommended to select a specific time interval since the total packet counters shown in all statistics are unscaled and represent the actual values. |
