This page contains multiple sections about different parameters of the system. | This page contains multiple sections about different parameters of the system. | ||
The System description describes system parameters such as the firmware version and the installed CPU cores and memory. | The System description describes system parameters such as the firmware version and the installed CPU cores and memory. | ||
The System utilization summarizes statistics about the current utilization which depends on the actual network traffic. | The System utilization summarizes statistics about the current utilization which depends on the actual network traffic. | ||
* Processing packets since: This is the time since the packet processing has been started. This can be the uptime of the system but packet processing can be manually restarted for various reasons (replaying pcap files, clearing all data, changing some configuration settings, etc.) | * Processing packets since: This is the time since the packet processing has been started.

* Data stored for last: This value describes for how long the Multimeter contains information from past traffic. | * 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. | 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. | Once the memory is fully utilized, older data will be automatically removed in favor of new data. | ||
* Estimated data store time: This value is calculated based on the current data store time and the memory utilization. It gives an indication for how long data can be stored once the memory is fully in use (which is automatically adjusted to 90%). | * Estimated data store time: This value is calculated based on the current data store time and the memory utilization.

* 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 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. | ||
* Memory utilization: The current utilization is printed together with a graph about the change of the utilization over time. | * Memory utilization: The current utilization is printed together with a graph about the change of the utilization over time. | ||
The Multimeter uses an automatic cleanup mechanism to remove old data in favor of new data. | The Multimeter uses an automatic cleanup mechanism to remove old data in favor of new data. | ||
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. | 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. | ||

The Status page lists possible problems occurred during packet processing. This includes bypassed packets in case of system overload, program restarts, and other problems. | The Status page lists possible problems occurred during packet processing.
