Like CET log files, Catalogues also create log files for logging error messages and other valuable information for debugging.

Each log entry is timestamped. The logs are also rotated like CET logs.

There should be 5 log files with the first one named Catalogue.cmtxt, followed by Catalogue1.cmtxt and so on. They are ordered by the time they are created.

The logs can be found at

• C:\Users\user\AppData\Local\CET Data\VersionNumber

Content

What the logs contain.

• The date the log was started
• Setup of connection and if the relevant ports are open.
• The list of registered catalogue database files along with their id.
• The status of the background sync task used to sync the catalogues
  • This can include information such as the duration between the current and previous sync.
  • If the download queue is busy
• The number of files queued to download for each catalogue, with some names of the files that are downloaded
• The catalogues that are being registered locally in CET as the system loads up.

Navigation

Similar to error navigation for CET log. Clicking in CET Studio on an error or warning should bring you to the location of where the error/warning occurred.

Common Errors

netstat failed.

Couldn’t find available ports for connection
