* Data stored for last: This value describes for how long the Multimeter contains information from past traffic.

The storage duration depends on the network traffic, the configuration settings, but also the amount of memory available in the system.

Once the memory is fully utilized, older data will be automatically removed in favor of new data.

* Packets stored in ring buffer for last: If a storage device is used for a packet ring buffer, this time indicates for how long packet data has been stored in the buffer.  
* Packets stored in ring buffer for last: If a storage device is used for a packet ring buffer, this time indicates for how long packet data has been stored in the buffer.  
This means that network traffic can be extracted from the past within this time period.  
:This means that network traffic can be extracted from the past within this time period.  
The duration may be larger than the data store time or even shorter, depending on the actual network traffic and the size of the storage device and ring buffer.

The available memory should always be used as much as possible and the cleanup mechanism ensures that approximately 90% of the system memory is in use.

If the load hits 100% for a longer period of time, it means the system is overloaded for the current network traffic.

When this happens, usually some network traffic can no longer be analyzed and packet drops occur.
