If you have ever looked in the /cfusion/log/ directory you have probably seen one or more of the many Cold Fusion generated error/information logs. These text files can easily grow to hundreds of MB and contain the best indicators of 'what happened'. As with any other service or application, regular review of system logs should be part of normal administration. Unfortunately, because of their large size and the fact that the data is segmented into so many logs, it is difficult to get a complete picture of performance, problems, and failure.
Developers who work on a dedicated server can use the Cold Fusion Administrator to view these logs. This can be accomplished clicking on "Log Files" and then downloading the entire log via a browser. Unfortunately, this is usually not possible given the size of most logs and remote connection speed.
For shared developers, the critical information is unavailable due to the nature of the shared environment and security. In most cases, a developer only knows what a site user tells them or what they trap using CFTRY/CFCATCH and CFERROR. Even with these mechanisms in place, the larger picture is unavailable and the majority of performance issues go unnoticed and unattended.
