FlowTracker generates RRD-based graphs of flow data on an ongoing basis, much like FlowScan and CUFlow. Each graph you create is called a tracker. One tracker graphs either inbound or outbound traffic, but not both. FlowTracker is much more flexible than FlowScan, but that flexibility also makes it unsuitable for customers or management to access directly.
Like FlowScan, FlowTracker creates RRD files from
flow-capture files as they're created. Rather than moving flow files, however, FlowTracker uses two processes to watch the
flow-capture directories for changes and to read each new flow file as it's closed. If these processes stop, FlowTracker will not update RRDs for new flows or create new graphs.
