[mrtg] Introduction and Question

I am new to this list and would like to introduce myself. I am currently
the IT Director of a mid-sized law firm. We have 25 locations throughout
the United States varying in size. I have used MRTG for network monitoring
in one form or another for about 12 years.
Now, my question; we are monitoring our 25 locations from a data center in
Atlanta. Our latency to varies from between 30ms to 55ms depending on the
location. We currently have our polling interval set to 5 minutes which I
believe is the default. Of course this is controlled by Cron (we are
running on Linux). Is it reasonable for me to think that I can set the
polling interval to 5 seconds and get a good response? My experience in
general has been that getting results back from the SNMP queries of the
routers takes longer than this. Net/net I end up with missed samples etc.
If this is not reasonable, can you recommend a tool that can help me get
this level of granularity on network performance? My suspicion is that I
will need to take a distributed approach placing an MRTG box at every
location and have it watch the WAN port for that location. With this
approach is it reasonable for me to expect a polling interval of 5 seconds
to be successful?
Any thoughts, recommendations, etc is greatly appreciated.
