<div dir="ltr"><div><font face="arial, sans-serif">I really like to use Mikrotik's "The Dude" for the SNMP graphing and value history. It has a lot of value, though it may not do some of the really fancy things (ie: Google Earth API's) that other applications do. But for free, it's a powerful tool to use in conjunction with the Mikrotik appliances (and other vendors if you're willing to add the MIBs)!</font></div>

I don't know that I'd replace that with the last good value, as that's no longer a true representation of the network, but I don't think I'd be opposed to having that data be potentially in the info box, though it would require some more work to set up.</span><br style="font-family:arial,sans-serif;font-size:13px">
