We're monitoring about half a dozen web sites at our provider over the internet with content scan. We get about a dozen or so single poll misses every day. We're monitoring for a string near the end of the pages to make sure we can at least load them that far. The misses appear at random, and don't seem to be connectivity-related. Granted there's an implied problem with doing this over the Internet, but pings always work and the pages never seem to have a problem from a user point of view.
We've increased the timeouts to 30 seconds, but that doesn't appear to help much, if at all. I'm not convinced this is normal. Circuit bandwidth at either location and sustained device latency in the path are for sure not the issue...at least that we can tell with sniffers and other apps. WhatsUP is 8.0, but it was the same at 7.2. Map polling is once per minute. There are only 25 or so devices on this particular map. Server is a dual 2G CPU, 2B memory, running Gig Ethernet and both ends have a 10Mb pipe to the Internet. No other problems with whatsup...runs very clean managing about 350 devices and interfaces including 27 regional offices over frame-relay. Using ping instead of content scan results in no failures. Before I go and change log triggers to 2 or more, does anyone else have any ideas? Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
