I understand that, but the graphs are quit misleading. For example, I was
installing software last week that made the graphs in my real-time monitor
nearly flat-line at 5Mbps for 40 minutes. I went back and looked at the MRTG
graphs and it showed one tiny spike at 2.5Mbps.
The real "problem" arises because our ISP bases almost all of their planning
off of these graphs. During these times where I watch the W2K3 network monitor
and see it flat-line with traffic, the network response time becomes
horrendous, making it almost unusable for 15-20 minutes at a time. When I
report this, they always response with a statement saying we're not coming even
close to our bandwidth limit (according to MRTG), and that bandwidth cannot be
the problem.
I'm trying to figure out how to use the "ISA Server Performance Monitor" to
show them the problem, but haven't quite gotten that down yet.

Well, don't forget that MRTG polls your router at each five minutes. If it
wasn't allocating your bandwidth during the whole 5 minutes, it won't flatline
;)

Does ISA 2004 support SNMP? I was trying to figure out a way to get
MRTG to graph the traffic.
On that same note, what do you guys think of MRTG? One of my ISPs
literally swears by it, convinced that that what MRTG shows is exactly
what you are using, and it is causing us a lot of problems. I have
numerous examples of times when I've maxed out my bandwidth, causing it
to flatline the real-time monitors, and MRTG will show me using only a
third of my allocated bandwidth.
