 ## NuixDiagnostics
 
-When there is a problem, it is helpful to capture a snapshot of the state of things for trouble shooting purposes.  In the Nuix Workbench GUI we can generate a diagnostics file with the click of a button.  When using the Java engine API we have to do a bit more work.  The class [NuixDiagnostics] provides a method [saveDiagnostics](https://nuix.github.io/Nuix-Java-Engine-Baseline/com/nuix/javaenginesimple/NuixDiagnostics.html#saveDiagnostics-java.lang.String-) which can generate a Nuix diagnostics file for you.  The method accepts as an argument the directory (as a String or [java.io.File](https://docs.oracle.com/javase/8/docs/api/java/io/File.html)) to which the diagnostics zip will be saved.  The generated zip file will automatically be given a time stamped name in the form `NuixEngineDiagnostics-yyyyMMddHHmmss.zip`, for example `NuixEngineDiagnostics-20200408113545.zip`.
