Traffic Analyzer
Monitoring traffic in terms of its volume is very useful for performance and
capacity planning purposes. At times it is also useful to understand the type
of traffic that is flowing through the network. In the event of an unexpected
increase in traffic, it can be very helpful to analyse the traffic by protocol
type e.g. IP, ARP, RARP, IPX, and be able to compare to previous analysis data.
The Traffic Analyzer probe looks inside the Ethernet packets and unravels them
to reveal the type of protocol that they are carrying. This probe is able to
show bandwidth usage between source and destination addresses broken down by
protocol. It is possible to set up various profiles to aggregate source and
destination addresses in to networks or subsets of networks. These profiles
can be separately monitored with different threshold values for alerting purposes.
The probe comes predefined with a set of system counters such as all Ethernet
traffic or all TCP/IP traffic.
All the data from this probe can be passed to the Service Level Manager for
inclusion in performance trending reports.
