Module settings

Some measurement modules have separate settings that influence the level of information measured.

Capture traffic

A detailed description about the capture module configuration settings can be found in :Capture module.

IP statistics

The IP module can be configured to store less information for significant less memory usage and slightly better performance.

• Store connection information for every IP: This option is enabled by default. When enabled, the IP measurement module stores every connection for each IP. This includes historical packet counter so you can see for individual connection at which time the connection transferred which amount of data. Connection data will be stored as long as possible regarding the total memory usage. Disabling this option will increase the minimum storage time significantly.
• Store layer 7 protocol information for every IP: The network protocols and their historical traffic data is stored for each IP if this option is enabled. Disabling this option will increase the minimum storage time slightly.
• Track number of new connections for every IP: When this option is enabled, TCP connections per IP will be tracked. Connections are divided into valid and invalid connections for server and client direction and the amount is shown. Disabling this option will increase the minimum storage time slightly.
• Store traffic history graph for IP peers: This option allows enabling or disabling the traffic history graph that is shown per peer in the "Peers" tab for an IP. Disabling this option will increase the minimum storage time slightly.
• Enable RTP measurement: This option allows enabling or disabling of RTP related statistics that are shown in the "RTP statistics" tab for an IP. Jitter and MOS calculation in the :Sip module` also depends on this switch. Disabling this option will increase the minimum storage time slightly.

Interface and MAC throughput

The throughput measurement module can measure interface throughput with a configurable resolution. The module can report its measurements via IPFIX or generate incidents as soon as a configured threshold exceeds. It can be configured as follows:

• Duration of one measurement interval in milliseconds: The measurement interval in milliseconds. For each interval all packets are aggregated until the interval duration is over and a new interval starts.
