ThingWorx Model Definition and Composer > System > Logs
  
Logs
The logs record information in regards to what is running and what is happening, particularly errors. A Recording Level can be set for each log in Monitoring>Configure. Depending on the Log Level , you will receive more and more granularity of what is going on in the system. The logs are kept in separate files on the server in /ThingworxStorage/logs.
* 
Monitor your log sizes and purge them consistently, by backing up the files first or discarding them.
Each of these logs can be filtered using the Date/Time filter, the User filter, the Levels range, and can be limited to a number of Rows. The content that is logged to a particular log is governed by the settings configured in the System Property Editor.
Application Log
The Application Log contains all the messages that the ThingWorx application logs while operating. Depending on your settings, this can display errors only or each individual execution that the platform performs.
Communication Log
The Communication Log contains all communication activity with ThingWorx.
Composer Log
The Composer Log records all activity performed in the Composer and its interaction with the platform layer.
* 
The Composer Log is not available in ThingWorx 8.3 and later.
Configuration Log
The Configuration Log contains all the messages that the ThingWorx application generates in regards to any create, modify, and delete done in ThingWorx . For example, if a Thing or Mashup is created, modified or deleted, it will log that information.
* 
This is currently not usable for roll-backs.
Database Log
The Database Log contains all messages related to database activity.
Security Log
The Security Log contains all the messages that the ThingWorx application generates in regards to Users. This can be logins as well as page requests depending on the Log level.
Script Log
The Script Log contains all the messages that the ThingWorx application generates while executing JavaScript services. You can use the logger.warn (or info, trace, debug, error. By default, the log displays warn and error, so we recommend using warn) function to log information to this script log from the services you are running. Generally, ThingWorx will only publish errors to this log incurred while running a service.
Script Error Log
The Script Error Log contains the stack trace for scripts created in the platform and is only available in the ScriptErrorLog.log file located in ThingworxStorage/logs.
