[c-nsp] sla metrics report

[Tom]

Hello
I'm trying to see if anyone used any open source tools that shows you
a nice sla metric for rtt or packet loss just like these from savvis
and internethealthreport:

http://ipsla.savvis.net/Matrix.jsp?report=T&region=US-US&refresh=60

http://www.internethealthreport.com/Main.aspx?xAxis=Metric&yAxis=Origin&zAxis=Destination&nAxis=Period


The source for these would  be Cisco's IP SLA

Thank you.
