Add Port and Netflow Processing Threads links at top of page.

Located at System > Receivers.

Here you can view and edit GigaFlow's defined Netflow receivers.

It is important to ensure that the installation is ready to listen. Senders on your network will be configured to send to the GigaFlow server address and to a defined port; these must match the receivers.

GigaFlow is built to receive and process flow records and session-based syslogs. GigaFlow can also process syslog messages relating to specific user or IP authentication details.

Flow records are processed automatically into the flow databases. The records are also checked against blacklisted IPs and against defined Profilers. See System > Blacklists and Profiling.

The syslog messages are sent to the syslog processor for parsing.

Existing Ports

Here you can see the existing listener ports available and if they are receiving flows or syslogs.

You can select the number of ports to show from the dropdown menu above the table, i.e. 10, 25, 50, 100 or all. The default is 50 items. The total number of ports is displayed at the top of the table. The information displayed includes:
