ArcGIS Server logs are great but the built-in management system is very bare bones. It would be great to have a more robust system for emailing alerts, errors, etc...
Does anyone use any third party log management systems or have created their own add-on?
for example, did you try SQLLog (http://www.arcgis.com/home/item.html?id=dc2f18833a6a48139a19aad11a5a93af )?
As soon as the log data is stored in your database you could think of writing some scripts to analyze events, send mails, create charts and reports etc.
