The UiPath.Vision.Host Diagnostic logs enable you to collect information regarding OCR engine errors.
To collect information regarding OCR errors, you can enable the generation of the diagnostic log files by adding the following
lines to the
<Installation Folder>\NLog.config
file:
<target xsi:type="File" name="visionHostFile" fileName="${LogDirectory}/${shortdate}_VisionHost.log" layout="${time} ${level}
${message}" concurrentWrites="true" />
<logger name="UiPath.Vision.Host.exe" minLevel="Trace" writeTo="visionHostFile" final="true" />
Note: Editing the
NLog.config
file requires administrator permissions.
The log files are generated at the path specified in the
<Installation Folder>\NLog.config
, under the visionHostFile
parameter. The default value is %localappdata%\UiPath\Logs\${shortdate}_VisionHost.log
.
Note: Editing the
NLog.config
