I see that you are using WhatsUp Gold v8.0 and that means that you already have a fix 
to what we called the "chunking" problem.

ie:

Expect=<html>.*</html>

If <html> is found in the 1st chunk of data received and </html> is not found in the 
1st chunk but in a subsequent chunk then the check should pass OK - but was not until 
v8.0.

So..  a couple of questions to help clarify things:

1) How big are the pages being monitored?

2) Are the pages dynamic?

3) Is the string being looked for an exact string or based on an expression?

Subject: [WhatsUp Forum] HTML Content Scan 


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?
