=== External timestamps === | === External timestamps === | ||
When this option is enabled, the system will use timestamps contained in the packet data instead of timestamps measured at packet arrival. Currently, only the Arista timestamp format is supported. If this option is enabled, packets without an external timestamp will not be analyzed. The current number of packets that are dropped because they do not contain an external timestamp is displayed in the active interface overview table of the top-user dashboard. If there are no packets with external timestamps arriving the time of the packet processing will effectively stand still and most graphs will not make progress in live-mode. | When this option is enabled, the system will use timestamps contained in the packet data instead of timestamps measured at packet arrival.

=== Memory utilization limit === | |||
This option allows to reduce the limit until old data is removed from the in-memory database. By default the system tries to target 90% memory utilization. In some case, the load might be too high to match this limit. A smaller limit may enable the system to keep the target memory utilization and perform better in general. | |||
