In many cases, it s best not only to detect and catch errors but to log them as well. For example, some problems may occur only when your web server is dealing with a particularly large load. Other problems might recur intermittently, with no obvious causes. To diagnose these errors and build a larger picture of site problems, you need to log errors automatically so they can be reviewed later. The .NET Framework provides a wide range of logging tools. When certain errors occur, you can send an e-mail, add a database record, or create and write to a file. We describe many of these techniques in other parts of this book. However, you should keep your logging code as simple as possible. For example, you ll probably run into trouble if you try to log a database error to another table in the database. One of the best logging tools is provided in the Windows event logs. To view these logs, select Settings Control Panel Administrative Tools Event Viewer from the Start menu. By default, you ll see three logs, as shown in Figure 7-6.

Figure 7-7. Event information One of the potential problems with event logs is that they re automatically overwritten when the maximum size is reached (typically half a megabyte) as long as they re of at least a certain age (typically seven days). This means application logs can t be used to log critical information that you need to retain for a long period of time. Instead, they should

be used to track information that is valuable only for a short amount of time. For example, you can use event logs to review errors and diagnose strange behavior immediately after it happens, not a month later. You do have some ability to configure the amount of time a log will be retained and the maximum size it will be allowed to occupy. To configure these settings, right-click the application log, and select Properties. You ll see the Application Properties window shown in Figure 7-8.
