[Zope] error-handling product?

[Dylan Reinhardt]

Hi all,

So I'm in the habit of configuring standard_error_message to kick out an 
e-mail under certain error conditions.

That usually works fine, except now I've got a site that -- for reasons not 
worth going in to -- creates hundreds of errors per day because there's one 
feature that actually depends on *not finding* an image file.  Suffice it 
to say that wasn't my first choice of how to design it.  Be that as it may, 
I don't want to suppress reporting of "not found" errors, just those that 
follow a particular pattern... and that takes me at least a couple steps 
beyond what DTML should be asked to do.

I'm thinking of writing an error-handling product, but since errors are 
such a basic fact of life, I'd be surprised if something didn't already 
exist.  A Google search on zope, error and product turns up nothing of 
interest, of course... the words are used together far too commonly.

Does anyone know if such a thing already exists?  If so, would you be so 
kind as to point me to it?

TIA,

Dylan
