    I have a WRT54g v3.1 running DD-WRT sp1 (4-13-06)...

    I am trying to figure out what is the best tool to use to monitor my network and bandwidth. I have WinXP.

    Here is what I have found so far:
    1. LinkLogger - $50
    2. WallWatcher - FREE
    3. Rflow Collector - FREE

    Which is best and why?
    Please let me know if there is something else better out there.

    I used RFlow Collector is free and included in the dd-wrt firmware. Haven't ry the others you mentioned, but they seem more details

    Any chance these app's effect the CPU and Memory load on the WRT54g differently?

    If this can be proven, I would expect the Rflow Collector to be the best (preformance wise) since BrianSlayer wrote it, and it might work better with DD-wrt then the others...

    Any thoughts?

    Hmm. I would tend to doubt it.

    Most of these packages work by capturing the log data that is sent from the router. The router sends the same data on the same UDP/IP port to whatever IP address you tell the router to send it to, then the reporting application simply captures those logs and analyzes them.

    The only load is the router having to take the event and do a simple send of the data using the UDP port to the specified IP address. The router does not know, and is not affected by, exactly what app receives and processes the data it sent.

    I can see where different packages could have a serious impact on CPU/memory usage on the PC they are running on, but frankly the load on the router should be exactly the same no matter what package is capturing the data (in fact, since these are UDP packets with no acknowledgment expected, the load on the router should be the same even if nothing is capturing them - the router is just tossing log entries into the void).

    How about Ntop? :thumb:

    I think what you are looking for is something like PRTG or MRTG - the log viewers are simply syslog viewers, they cant really tell you that much about your bandwidth or utilization.

    The PRTG or MRTG tools use SNMP to collect real time data from the router.
