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. ======================== Gary L.
