Position the mouse cursor over the NetFlow Database icon to view the database edition and current size (in megabytes). For more information, please see About NetFlow Monitor database and service icons. Position the mouse cursor over an icon to view size and status information. These icons display information about the NetFlow Monitor database, archive database, and NetFlow Monitor service. NetFlow Monitor database and service iconsĭatabase and service icons are located in the bottom right of the page. Use the links at the bottom of the interface details to view the Interface Details and Interface Overview reports, as well as the NetFlow Interface Properties. The status of the interface either Up, Down, or Unknown. The speed at which data is flowing from the interface. The speed at which data is flowing to the interface. The type of the interface for example, Ethernet CSMA/CD. The last time traffic transmitted over the interface. The Interface Traffic report for the last half-hour is displayed at the top of the interface's details. Note: A link for the WhatsUp Gold Device Status report appears only if the source is monitored in WhatsUp Gold. Use the links at the bottom of the source details to view the NetFlow Source dialog, and the WhatsUp Gold Device Status report. Note: If any traffic has been received within the last 30 minutes, the traffic status is displayed as receiving. Whether NetFlow Monitor is receiving traffic from the source either receiving, or not receiving. The last time traffic was received from the source. The number of flows per minute (fpm) reported by the source for the last half-hour. The percentage of packets received versus packets lost by the source since the collector service was started. The number of packets sent from the source but not received by the collector since the collector service was started. The number of packets the collector received from the source since the collector service was started. The version of NetFlow the source uses when exporting NetFlow data. Consult this workspace report for information on configuring your routers to send NetFlow data, and for other general NetFlow Monitor configuration information. Note: If you have no enabled NetFlow sources at this time, a Welcome workspace report is displayed on the right side of the NetFlow Home page. The right side of the page gives detailed information about a selected source or interface. Outgoing traffic is reported as a percentage of usage according to the interface's speed, and as the number of outgoing bytes per second (bps). Incoming traffic is reported as a percentage of usage according to the interface's speed, and as the number of incoming bytes per second (bps). For more information, see Configuring NetFlow sources. If you still do not see the router listed, check to see that the router is configured to send NetFlow data. Tip: If you do not see a source listed that you would like to monitor, first go to the NetFlow Sources dialog to configure source settings. Note: Interfaces can be hidden if you do not see an interface listed on this workspace report, check to see if it has been hidden via the NetFlow Interface Properties. For each source, the number of flows per minute (fpm) generated by all interfaces on the selected source over the last half hour is displayed. Use the collapse and expand buttons to show or hide source interfaces. Associated interfaces for each source are below the source name. In the list, sources are organized at the top level. Routers and switches that have been configured to send NetFlow data to NetFlow Monitor and are enabled in NetFlow Monitor are listed in this column. The left side of the page lists each of the monitored sources and the interfaces associated with each source. You can also access NetFlow Monitor database and Data Collector Service information using the links at the bottom right side of the page. Use this page to view high-level information about network traffic and flows and to drill deeper into each interface for more detailed information. ![]() So, in the above scenario, even if netflow-sampler is chosen as 'both', traffic would not be seen as different with respect to ingress and egress.The NetFlow Monitor Home page provides overview information about the network sources that NetFlow Monitor is monitoring. ![]() If the connection is from Client to Server, either it is download or upload, it is still in the same direction and is in one session.ġ) If the client downloads or uploads still it is in one session. Rx: Monitor received traffic on this interface.īoth: Monitor transmitted/received traffic on this interface. Tx: Monitor transmitted traffic on this interface. The following options are available for the Netflow sampler:
