Where Are My IIS Logs?

Although you may have bucket loads of logging taking place in your web applications/sites, the IIS logs can be helpful in certain circumstances. Use the following steps to track down these tucked-away log files:

1. Open Internet Information Services (IIS)
2. Right-click the desired web site and select properties
3. On the Web Site tab, at the bottom is the Active Log Format; select the properties button next to it
4. You'll now have a box that contains the log file directory and the log file name. Together they make the full log path.

In this window you can also change useful settings like what request/response details are recorded in the logs. Some useful options not selected by default are bytes sent, bytes received and referrer (useful for tracking 404s in certain cases).

Extracting useful info from these log files is another blog post all together ;)
