Enable Tracing in SENTINEL – Requires restart of SENTINEL service (Label Print Manager) after making changes.

SENTINEL Manager > Tools > Tracing > Activate Tracing

  1. Trace Level = Highest
  2. Trace Files Path = C:\TEKLYNX_TRACE\SENTINEL
  3. Max File Size (kb) = 10240

*Note: Older versions of SENTINEL did not have the “Highest” setting. To enable the highest level of tracing, the screen needs to be configured as above, then hold CTRL + Shift and type DEBUG.  Once done a screen will pop up in French, and this will enabled the “Highest” setting

Log files in SENTINEL are not the same as trace files but can be useful for tracking down timestamps of the problem. These files are configured per SENTINEL watch, and most likely will not be consolidated with other trace files. Consolidation into Trace files directories might be necessary to understand the issue. If not, please take not of relevant logs and capture them accordingly.

Note: Remember to turn the logging off when you are done.

Important Note

Take note of the folder location for the log file. You will need to navigate back to it the recover the log files.
