Measures reported by TopDestTest

If the NetworkInterfaceTest test reveals that a specific interface is handling an abnormally high volume of traffic or is consuming bandwidth resources excessively, you may want to know where this traffic is headed. This is where the TopDestTest test helps!

This test discovers the top-n destinations (in terms of volume of traffic) of the netflows through each interface on a target device, and for each destination, reports the data traffic (in bytes and packets) leading to or coming from that destination. This way, the test points you to the destinations that generate the maximum traffic. The bandwidth used by each destination when receiving / transmitting data is also reported, so that you can quickly identify those destinations for which traffic has been consistently bandwidth-intensive.

Outputs of the test : One set of results for every top-n destinations (in terms of traffic volume) on each interface supported by the target device.

First level descriptor: Interface name

Second level descriptor: Destination

Metrics are also reported for an Others descriptor. Netflow statistics pertaining to all destinations that are not the top-n sources are aggregated and presented against the Others descriptor for each interface.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
bytes Indicates the total amount of data transmitted and received by this destination during the last measurement period. KB Compare the value of this measure across destinations to identify which destination host is contributing to the high level of network traffic.

Use the detailed diagnosis of this measure to determine the top netflows (in terms of the volume of data transacted) to this destination, and the amount of data transacted in bytes and packets in every flow. With the help of this detailed diagnosis, you can quickly compare the top netflows, know which netflow generated the maximum traffic, and figure out to which destination that traffic was headed. Once the problem destination is isolated, you can then investigate why traffic to that destination is high.
packets Indicates the total number of packets transmitted and received by this destination during the last measurement period. Packets Compare the value of this measure across sources to identify which destination host is contributing to the high level of network traffic.
bytesPerSec Indicates the rate at which this destination transmitted/received data. Kbps  
packetsPerSec Indicates the rate at which this destination transmitted/received packets. Packets/sec  
trafficRate Indicates what percentage of the total traffic on this interface was to this destination. Percent A value close to 100% for this measure indicates that traffic to this destination is imposing the maximum load on the network. If users complain of a latent network, you can compare the value of this measure across destinations to accurately identify the destination that is responsible for any congestion on the network.
BWUtilized Indicates the bandwidth utilized by this destination. Percent A value close to 100% is indicative of excessive bandwidth utilization by this destination when receiving data.

If users complain of a latent network, you can compare the value of this measure across destinations to accurately identify the destination that is responsible for any congestion on the network.
in_traffic Indicates what percentage of total incoming traffic on this interface pertains to this destination. Percent  
out_traffic Indicates what percentage of total outgoing traffic on this interface pertains to this destination. Percent  
in_bw Indicates the percentage of bandwidth utilized by traffic coming into this interface when receiving data for this destination from different sources and when receiving data from this destination. Percent A value close to 100% is a cause for concern as it implies a potential congestion in incoming traffic on this interface.
out_bw Indicates the percentage of bandwidth utilized by traffic going out of this interface when transmitting data to this destination and when transmitting data for this destination to a source. Percent A value close to 100% is a cause for concern as it implies a potential congestion in outgoing traffic on this interface.
in_octets Indicates the amount of data received by this destination. KB Compare the value of this measure across destinations to know which destination is receiving maximum data over this interface.
out_octets Indicates the amount of data sent by this destination. KB Compare the value of this measure across destinationsto know which destination is transmitting maximum data over this interface.
in_packets Indicates the number of packets sent by this destination. Number  
out_packets Indicates the number of packets received by this destination. Number  
in_octetsRate Indicates the rate at which data is received by this destination. Kbps If the value of this measure consistently drops for this destination, it could indicate an incoming traffic congestion.
out_octetsRate Indicates the rate at which data is sent by this destination. Kbps If the value of this measure consistently drops for this destination, it could indicate an outgoing traffic congestion.
in_packetsRate Indicates the rate at which packets are received by this destination. packets/Sec If the value of this measure consistently drops for this source, it could indicate an incoming traffic congestion.
out_packetsRate Indicates the rate at which packets are transmitted by this destination. Packets/Sec If the value of this measure consistently drops for this destination, it could indicate an outgoing traffic congestion.
