System tab shows performance and system traffic for NetFlow module= . Traffics available are:
UDP Packets show number of received and discarded packets. Viewing = packet collection is useful for checking if your NetFlow Analyzer experienc= ed some packet losses.
To access this view, go to Top N > System > UDP Packe= ts.
In some critical events such as network attack, having some amount of pa= cket losses is acceptable.
It is up to you to decide much buffer memory to reserve in order to coll= ect as much data as possible during overflows.
Number of flows gives you statuses on the data processing.
Flows are categorized into:
To analyze flow processing, go to Top N > System > Flows= strong>.
Dropped flows occur once your buffer is full. Flows received upon are no= t processed and displayed, and their amount is visible in the Dropped field= .
Unlicensed flows (dark red on the graph) mean that your network devices = are exporting more flows than your license allows. These flows will not be = processed by aggregator and, therefore, information provided by them will n= ot be included when creating and displaying traffic. If flows appear in the= Unlicensed field, you should upgrade your license. Read more about License Upgrade.
Within Performance overview you can see various metrics that show how ef= ficient is your application.
Available metrics are:
Keep an eye on the Heap memory and how it is affected by the increase in= monitored nodes and counters (each time you add a node or create a TopN ru= le this numbers are modified).
