Website stats: What is the average rate of error messages to overall impressions?

An AIMS member sends in the following question...

Is it standard practice to include 404 error messages in website reports?

If so, is there an average/acceptable error rate/percentage of overall impressions? So for example if a site gets 1 million page impressions a month, error messages should make no more than 2% of that overall amount.

Can anyone jump in with what they've found?
