If you're involved with troubleshooting your Cognos 8 environment then you should become familiar with your logging tools. From within Cognos Connection you can set the logging levels for your C8 environment. This will allow key information such as user logons, error messages, and report requests to be captured in the log files such as cogserver.log.
You would set the level of detail to log through the Server Administration tool. It will provide you with 5 levels of logging -- Minimal, Basic, Request, Trace, Full. You should review the performance impact on your environment before keeping the selected logging level. It would be a safe assumption that a FULL logging setting should not be applied to your PRODUCTION environment. It is recommended to set your environments to either Basic or Request logging levels.
