Top Devices (Last Hour v Last Week Hour)

This is a summary of traffic across the busiest infrastructure devices over the past hour. Infrastructure devices are routers sending flow as well as other Layer-2 devices that are not sending flow but sending ARP and CAM Tables. The information displayed includes:

• Avg Bits/s: average traffic per second per device.
• Percentage: this is the proportion of all traffic over the past hour seen by a particular system/router.
• Position relative to the same hour last week: this is the percentage increase or decrease in traffic per second per device compared with the same hour last week.

When more than ten devices are registered, the full list can be displayed by clicking the drill down icon. This displays a tabular version of all the data, with a CSV export option.

Top Interfaces (Last Hour v Last Week Hour)

This is a summary of traffic across the busiest interfaces over the past hour. The information displayed includes:

• Avg Bits/s: average traffic per second.
• Max: this is maximum traffic volume seen in the data set.
• Percentage: this is the proportion of all traffic seen by a particular interface.
• Position relative to the same hour last week: this is the percentage increase or decrease in traffic per second per interface compared with the same hour last week.

When more than ten interfaces are registered, the full list can be displayed by clicking the drill down icon. This displays a tabular version of all the data, with a CSV export option.

See Configuration > Infrastructure Devices for setup instructions.

Top Traffic Groups (Last Hour v Last Week Hour)

This graph shows the traffic associated with the busiest traffic groups over the past hour. The information displayed includes:

• Avg Bits/s: average traffic per second per traffic group.
• Percentage: this is the proportion of all traffic over the past hour seen by a particular traffic group.
• Position relative to the same hour last week: this is the percentage increase or decrease in traffic per second per traffic group compared with the same hour last week.

When more than ten traffic groups are registered, the full list can be displayed by clicking the drill down icon. This displays a tabular version of all the data, with a CSV export option.

Top Applications (Last Hour v Last Week Hour)

This graph shows the traffic associated with the busiest applications over the past hour. The information displayed includes:

• Avg Bits/s: average traffic per second per application.
• Percentage: this is the proportion of all traffic over the past hour seen by a particular application.
• Position relative to the same hour last week: this is the percentage increase or decrease in traffic per second per application compared with the same hour last week.

When more than ten applications are registered, the full list can be displayed by clicking the drill down icon. This displays a tabular version of all the data, with a CSV export option.

Top Source Addresses (Last Hour v Last Week Hour)

This graph shows the traffic associated with the busiest source IPs in the past hour. The information displayed includes:

• Avg Bits/s: average traffic per second per source IP.
• Percentage: this is the proportion of all traffic over the past hour seen by a particular source IP.
• Position relative to the same hour last week: this is the percentage increase or decrease in traffic per second per source IP compared with the same hour last week.

When more than 10 IP addresses are registered, the full list can be displayed by clicking the drill down icon. This displays a tabular version of all the data, with a CSV export option.

Top Destination Addresses (Last Hour v Last Week Hour)

This graph shows the traffic associated with the busiest destination IPs in the past hour. The information displayed includes:

• Avg Bits/s: average traffic per second per source IP.
• Percentage: this is the proportion of all traffic over the past hour seen by a particular destination IP.
• Position relative to the same hour last week: this is the percentage increase or decrease in traffic per second per destination IP compared with the same hour last week.

When more than 10 IP addresses are registered, the full list can be displayed by clicking the drill down icon. This displays a tabular version of all the data, with a CSV export option.
