The burst analysis module measures throughput per interface or MAC address and displays utilization graphs for fast recognition of bursts. | The burst analysis module measures throughput per interface or MAC address and displays utilization graphs for fast recognition of bursts. | ||

The burst analysis module measures throughput for every interface in a 1 ms interval. Measurement is always done on layer 1, the packet length accounting setting is ignored. | The burst analysis module measures throughput for every interface in a 1 ms interval.

Together with the interface throughput incidents you can easily see when bursts occured and how long they lasted. | Together with the interface throughput incidents you can easily see when bursts occured and how long they lasted. | ||
=== Utilization 100% configuration === | |||
Next to the graph the configured '''Utilization 100%''' threshold is shown and can be configured by clicking on the change link. | |||
For interfaces either the link speed or any other Mbit/s value can be used. For MAC addresses the tx and rx thresholds can be configured. | |||
The traffic’s bandwidth will be shown as '''Utilization >> 100%''' if it is larger than 105% of the configuration value. | The traffic’s bandwidth will be shown as '''Utilization >> 100%''' if it is larger than 105% of the configuration value. | ||
In case of PCAP analysis, the interface speed cannot set in advance since the interface numbers or not known and may differ from the interface of the device. Therefore, the [[Pcap analysis module#Analysis profiles|analysis profiles]] can be used to configure the interface speeds for each interface in the PCAP file or for all interfaces all together. | |||
