Do you have appropriate resources?
When running in either Performance mode or Professional mode a min 50G of disk is required and more depending on the number of Devices exporting to Netflow Auditor.
If using Netflow Auditor in Professional Mode a much large allowance of space should be available to record the flows. Flows can be profuse. Please see the knowledge base item NetFlow Auditor Sizing - Planning Disk Space Requirements
When using Netflow Auditor in Professional Mode or when using Netflow Auditor external Enterprise collector it is prudent to identify flows that can be reduced or even completely aggregated using Data Collection Tuning
.How many CPU's?
Multiple CPU’s will significantly speed query and processing time. Is Netflow configured correctly?
Check all interfaces are set to “ip flow ingress” to ensure NetFlow Auditor captures all the traffic in and out. Is SNMP accessible
Confirm and SNMP is correctly configured on your router and it can be reached and resolved from the Netflow Auditor server. If your SNMP is not setup correctly interface names cannot be resolved and interface bandwidth cannot be discovered.
Go to Configuration -> Device and enter your SNMP community string per Device or change the global snmp password in the Site administration screen. Click the line, click modify, enter string, click confirm, wait a few minutes. The resolve will take longer if the number of interfaces is large. Setup some base configurations
