These files contain general logging of Nutrient Workflow events as well as critical and informational messages helpful in troubleshooting if problems occur. If these files become large on your system, you can delete them at any time. Some of these logs will only show up if you have debug turned on in the nutrient workflow\app\settings\settings.config file. We are asked often what to look for in these files when implementing a monitoring tool. The answer is that you probably shouldn't. The Nutrient Workflow application has numerous self-checks embedded in the code. So, even though a message may appear in a log, there is a very good chance that the application already either worked around the issue or retried the same activity successfully before you are even alerted of an error. A good rule of thumb is that the Nutrient Workflow logs files should only be used to assist in troubleshooting user-facing issues. Almost every critical error will have a corresponding negative user interface impact. **nutrient workflow\app\scheduler\logs (v6 only):** * _< YYYY-MM-DD>_scheduler.log - contains information regarding scheduled reports and processes depending on your logger-config.json configuration. _ **nutrient workflow\app\service:** * _< instancename>_exceptions.xml_ - contains mostly critical and some noncritical errors relating to the function of Nutrient Workflow. Typically errors that cannot get logged to the database because of a database connectivity issue or any other system issues are logged here. If for some reason Nutrient Workflow does not function after an upgrade or a server reboot / IIS restart, you will want to take a look at this file. * __ _exceptions.xml - _contains error messages relating to the descriptor. As an example, _connections_exceptions.xml will show errors relating to database connections. * _SystemSettings.log_ - contains a log of the number of Nutrient Workflow instances and the number of settings per instance. For most installed customers this should be 1 and 47 respectively. It writes to this file anytime the first user hits the site after an application pool recycle or service restart. This is a verbose log and contains information as well as errors. **nutrient workflow\app\webserver\iisnode:** * _< servername>-<#>-stderr-<##>.txt _- contains both critical and non-critical messages relating to the function of Nutrient Workflow. If for some reason Nutrient Workflow does not function after an upgrade or a server reboot / IIS restart, you will want to take a look at this file. Most real errors will appear in this file along with verbose messages. * _< servername>-<#>-stout-<##>.txt _- contains both critical and non-critical messages relating to the function of Nutrient Workflow. If for some reason Nutrient Workflow does not function after an upgrade or a server reboot / IIS restart, you will want to take a look at this file. Most real errors will appear in this file along with verbose messages **nutrient workflow\app\webserver\logs:** * _< YYYY-MM-DD>_session\_stats_.log _- contains license usage stats. * _< YYYY-MM-DD>_error_.log _- contains errors of all kinds depending on what area of the application was affected (process, route, etc). This should be one of the first logs to look at when a user reports an error or an issue. * _< YYYY-MM-DD>_info_.log _- contains informational messages of all kinds depending on what area of the application was affected (process, route, etc). * _< YYYY-MM-DD>_warning_.log _- contains warnings of all kinds on what area of the application was affected (process, route, etc). **nutrient workflow\app\windowsservices:** * _< instancename>_exceptions.xml_ - contains mostly critical and some non-critical errors relating to the function of Nutrient Workflow. Typically errors that cannot get logged to the database because of a database connectivity issue or any other system issues are logged here. If for some reason Nutrient Workflow does not function after an upgrade or a server reboot / IIS restart, you will want to take a look at this file. * _SystemSettings.log_ - contains a log of the number of Nutrient Workflow instances and the number of settings per instance. For most installed customers this should be 1 and 47 respectively. It writes to this file anytime the first user hits the site after an application pool recycle or service restart. This is a verbose log and contains information as well as errors. * _< instancename>_sync\_log.xml_ is updated every time the [ADSync](https://www.nutrient.io/guides/workflow-automation/faq/how-do-i-import-active-directory-users-into-nutrient-workflow-using-adsync.md) application is run. It contains success and error logging. **nutrient workflow\app\windowsservices\tp\_logs:** This directory contains logs and errors from the Nutrient Workflow Task Processor. Error files are named yyyymmdd_tp.error. These files will list each instance the processor was able to hit, and the count of the notifications sent for reminders as well as the number of task timeouts for that instance. This is logged every time the Task Processor runs, which is every 5 minutes by default. **nutrient workflow\app\windowsservices\em\_logs:** This directory contains logs and errors from the Nutrient Workflow Email Monitor. Error files are named yyyymmdd_em.error. **ERROR\_LOGGER** This is a table that resides in your Nutrient Workflow database. You can run a select statement directly against the table with the tool of your choice to view its contents Aside from the files, folders, and tables listed above, the windows event logs will also hold valuable information in case of a problem. Normally the event logs are most useful for analysis if the files above are not being updated or recreated after deletion. The main locations for logged events for the application are in the \nutrient workflow\app\webserver\logs directory as well as the \nutrient workflow\app\webserver\iisnode directory. --- > Part of [Frequently asked questions](/guides/workflow-automation/faq.md) ## Related pages -
