list of isp realtime perfomance

(Some people use the phrase "weather report" instead of "traffic report")

1. What technology are you getting from the ISP (Frame Relay, MPLS, PPP, etc.)?
2. What is a use for the service (Internet, dedicated circuit, voice circuit, etc)?
3. What do you use the connection for (Internet browsing, Internet hosting, IP Telephony, etc.)
4. .... etc.

There are hundreds variants of using an ISPs. And depending of your goal, some tools could be useful in one case, and useless in another. For example, if you use the Internet for just browsing, the performance may be affected by (a) Your carrier, (b) intermediate circuits, (c) destination carrier, and (d) end host. For TCP applications jitter or latency have minimum impact, while for VoIP may be crucial. Most applications just do a PING or TRACEROUTE to a host you pick, but you cannot really tell why it behave one way or another. You need to decide what is most critical for you (for example, for VoIP "round trip delay", jitter, latency, etc.) and look for tools, provided by the router manufacturer. In case of Cisco, you may spend some money, and implement a Cisco NAM (Network Analysis Module). Or get IP SLA collector, and configure it to monitor your VoIP peers. Or get a span session to a sniffer, which will analyze traffic in a real time. But if you use a service for an Internet hosting, then you may be more interested in a TCP performance, in application response time, etc. And getting back to a technologies, you use. If you suspect, it's a "last mile issue", monitor a router for a technology-specific parameters, like dropped packets, "slowdown packets", etc.
