# Processing logging

> Enable trace logging for the FlexiCapture Processing Server and Processing Stations in Processing Server Monitor, and tune log size, count, and level.

Enable trace logging for the Processing Server and Processing Stations in the Processing Server Monitor, and then fine-tune the log files through the registry.

By default, processing logs are saved in `%ProgramData%\ABBYY\FlexiCapture\12.0\FlexiBr[Svc]\Logs`.

## Set up logging using the registry

You can adjust Processing Server and Processing Station logging through the following registry key: `HKEY_LOCAL_MACHINE\SOFTWARE\ABBYY\FlexiCapture\12.0\FlexiBr`.

You can modify the following parameters:

* `LoggingManagerMaxLogFileSize` — maximum allowed size of one log file in bytes (1 MB by default).
* `LoggingManagerMaxOldLogsFilesCount` — maximum allowed number of log files (10 by default).
* `LoggingManagerMaxOldLogsFilesSize` — maximum total size of all log files in bytes (10 MB by default).
* `LoggingLevel` — level of logging detail from 1 (minimum detail) to 9 (maximum detail). `LoggingLevel` is set to 5 by default.
* `LoggingFilter` — the types of events that will be logged.\
  Sample filter string: `+Licensing;+AppState;-*;+Monitoring`. This filter enables the Licensing and AppState logs. The Monitoring log is disabled by the `-*` mask.
