Anyone have recommendations for applications that graph
traffic/measure bandwidth through routers and/or servers? something
like mrtg? and/or something that measures latency? something like
smoke ping?
You should define better how you want to implement this. For instance
are you going to be using SNMP (which can snarf stats from another
machine), are you going to measure the local NI on the host itself,
or are you going to actually measure packets passing a "gate" by
sniffing them? Also are you interested in historical data or are
lossy solutions like RRD OK?
There's bmon, which is a bandwidth monitor that's very simple.
Available through fink. Runs even on my
Linksyshttp://people.suug.ch/~tgr/bmon/
ntop also runs on the local host and there's even a version I have
installed on my Linksys WRT54GS.
MRTG isn't "dead" but still widely used.
Cacti is good.
And on the high end their's HP OpenView.
And if you tcpdump to a database there's no end to what you can
accomplish in terms of reporting, graphing, latency detection, ...
This last solution is what we do for an ISP. Very powerful.
