The Flow Quality Analyzer (FQA) is a tool available since Flowmon version 12. FQA provides a quick and easy way to assess the quality of flows arriving at the collector without the need for third-party software.
To run the FQA, use the following command:
fqa <start|startd|stop> [udp_port] [collection_time] [max_used_disk_space_mb]
The main difference between actions start and startd is that startd will run the analyzer in a detached mode, that is, leaving the current terminal open for additional work.
Default parameters are 330s for collection time and 300MB for space used for capture. If these parameters are not provided, defaults are used.
The FQA will run alongside the Flowmon Collector and capture a copy of all arriving flows for analysis, thus using additional disk space. Depending on the capture size, the analysis could take some time.
