Expert Symptoms, Analyses, and Network Entities

Analyses

High rates of recurrence of specific symptoms or single instances of particular network events cause the software to assert that the network has a real problem. These are logged as analyses. Analyses should be investigated immediately. Counters for analyses can be used to trigger alarms.

Press the Analyses tab on the Expert window to view the diagnoses derived from the current packet analysis. Analyses display exactly like symptoms. See Figure 10- 1 and Figure 10-3 for examples.

Tables in the Detail Area for Analyses

The first list displays which types of diagnoses and how many of them are found in the connections between the two network stations.

The second list displays the network traffic of the first network station. It shows how many packets and bytes of data are sent and received by the station. It shows how many broadcast packets the station sent and the MAC addresses associated with the station.

The third list displays the network traffic of the second network station, if present.

The fourth list displays the network traffic between the two network stations. It shows how many packets and bytes of data are sent from the first to the second and the second to the first.

Entities

Surveyor extracts information from the data stream to form its network entity data- base. Entities can be DLC stations (physical and logical link layers), network stations (network layer), connections (transport layer), sessions (session layer), applications (presentation, and application layers), a subnetwork, a router, or other useful data entities.
