However, even with around-the-clock monitoring, every network is susceptible to bandwidth hogs, which can put enterprises at risk if they cause business-critical applications to slow down. Network administrators are the linchpin for maintaining a sound network infrastructure, which can often be a daunting task since you need to monitor and manage the network and servers 24x7. Network Bandwidth Monitoring Challengesįree Network Traffic Analyzer Why should you analyze network traffic?.Network Bandwidth Monitoring Best Practices.Intelligent Traffic Management with NBAR.Network Based Application Recognition(NBAR).Use a packet capture tool, such as WireShark, on the relevant interface and port to verify that the device is exporting data as expected. Verify that each interface for which you want to collect and view data is actively being monitored in SolarWinds NPM.įor any interface that you need to add to SolarWinds NPM, see Network Discovery Using the Network Sonar wizard.If your network device is of a different vendor, see the documentation of the vendor. Configure your network devices to export NetFlow data for each interface for which you want to collect the data.įor more information, see Device Configuration Examples.įor information on enabling NetFlow for Cisco Catalyst switches, see Enabling NetFlow and NetFlow Data Export (NDE) on Cisco Catalyst Switches.įor information on enabling NetFlow on Cisco ASA devices, see the SolarWinds KB Understanding Cisco ASA NetFlow.If you see a network device in your NetFlow Sources and you do not intend to collect NetFlow data from it, you can eliminate unnecessary traffic by turning off the export of data at the device.
