RFlow Collector

Discussion in 'DD-WRT Firmware' started by Wikking, Mar 25, 2005.

    I've tested the DD-WRT Firmware on a small network (3 WRT54G) and set the AP's to transmit RFlow / MACupd. But i have two major problems!

    First: The Upload/Download statistics is upated when download/upload of the file is finished.
    Second: Data is only recorded on the machine with RFlow Collector and not on the router itself!

    So my questions are:
    Is there a possibility to get "real" realtime data from the AP's? Cos if im lithstening to internet radio( for example) the program indicates that there's nothing downloaded at all (till i stop streaming). which is not correct...i swear! ;-)
    And second question: Is there a possibility to store the recorded data on one of the AP's and collect it once a day or once a week? And not having an extra machine runin all the day just to store statistics data!

    i dont think that it can do the real time logging.

    you can get realtime traffik data with snmp, but only for the interfaces. for the independent user statistic there is no real realtime way.

    logging data on the wrt itself is a little bit critical. if the memory is full, the wrt imediatly reboots and all is lost. so i will not do this. the wrt itself is not a logging station. its a router. realize that. it should be fast and not overloaded with functions. the centralized account management is really usefull if you log 30 - 50 WRT AP's on only 1 machine with detailed client statistics. thats why we created it and thats how we're using it here

    Im well aware of the memory problem! But i don't want such a detailed logging for each client. I thougt about a simple uipload/download logging for each client without ports. Or better a counter that has to be reset after tranfering the data to a specific machine in the network.

    It would be nice if there was a montly running total that got reset every month or 30 days (depending on your ISP) to track your total use for the month.

    we are already working in a mini rflow for the internal web server. but its too far to speak, "its ready now". the biggest problem is still the layout since this page is dynamicly created

    Sounds great.. The router is probably the best place to track in and out traffic for the network, since if it goes off line there can not be any traffic.

    Taking this one step further, I had a crazy feature idea.. Since QOS can already detect traffic and set a priority, I was thinking to help curb bandwidth use and going over ISP limits some sort of auto block or bandwidth reduction could be placed on specific protocols or categorys..

    Such as when you transfer 50 GB in a month all bulk traffic is blocked or gets its bandwidth cut in half.

    It can be hard to manage you monthly bandwidth use with multiple users on your connection. This would force limits.
