Analysing elmah logs

I am using elmah in some of my web application. I am wondering are there any reporting utilities or tools can analyse/scan all the logs and produce a report to show me the common errors in the log. I liked the one at http://demo.l4ndash.com/PageDashboard/Dashboard.aspx but it is for Log4Net and not Elmah.

What are Elmah logs?

ELMAH (Error Logging Modules and Handlers) is an application-wide error logging facility that is completely pluggable. It can be dynamically added to a running ASP.NET web application, or even all ASP.NET web applications on a machine, without any need for re-compilation or re-deployment.

Taken from a post on ELMAH's Google Group:

ELMAH permits you to download the entire log as a CSV. Using this option, you have two ways to analyze the data with existing tools. For example:

Excel for a quick analysis

Microsoft Log Parser as a more comprehensive query and analysis tool
