Does ELMAH have flood protection implemented and enabled by default?

Can anyone confirm that Elmah implements flood protection behavior and that this behavior is enabled by default, or is easily enabled via web.config? If so, is the time threshold configurable?

I proposed setting up the Elmah database schema to our database, but our DBA has legitimate concerns about error logs consuming significant storage space if an error occurs across the board for our hundreds of thousands or millions of web visitors. I thought I had seen behavior in Elmah to filter out duplicate exception logs if a 开发者_运维技巧certain time threshold had not been met, but I have not been able to validate this behavior doing a Google search for documentation on this feature.

In case you have not seen it, Scott Mitchell's article "Keeping ELMAH's Error Log Size In Check" touches on this subject, and may help.
