Accessing Log Files

If you need support using our products, you can shorten response times by sending us your log files. Accessing the log files is different in Windows and Linux:

Windows

Since
mvIMPACT Acquire 2.11.9

You can access the log files in Windows using wxPropView. The way to do this is described in Accessing log files.

Linux

Since
mvIMPACT Acquire 2.24.0

You can access the log files in Linux via /opt/mvIMPACT_Acquire/data/logs .

You can also extract the directory using the following command

env | grep MVIMPACT_ACQUIRE_DATA_DIR

or change the directory directly via

cd $MVIMPACT_ACQUIRE_DATA_DIR/logs

For older versions:

Like on Windows, log files will be generated, if the activation flag for logging called mvDebugFlags.mvd is available in the same folder as the application (however, using Windows log files will be generated automatically, because the applications are started from the same folder). By default, on Linux the mvDebugFlags.mvd will be installed in the installation's destination folder in the sub-folder "apps". For example, if the destination folder was "/home/workspace", you can locate the mvDebugFlags.mvd like the following way:

user@linux-desktop:~$                                                           // <- Starting the console window, you will be in the home directory: /home/
user@linux-desktop:~$ cd workspace/apps/                                        // <- Change the directory
user@linux-desktop:/home/workspace/apps$ ls -l                                  // <- List the directory

For log file generation you have to execute your app from the folder where mvDebugFlags.mvd is located. E.g. if you want to start wxPropView:

user@linux-desktop:/home/workspace/apps$ ./mvPropView/x86/wxPropView            // <- Start the executable from the folder, where \b mvDebugFlags.mvd is located.

Another possibility would be, to copy the mvDebugFlags.mvd file to the folder of the executable:

user@linux-desktop:/home/workspace/apps$ cp mvDebugFlags.mvd ./mvPropView/x86/wxPropView // <- Copy the log activation flag
user@linux-desktop:/home/workspace/apps$ cd ./mvPropView/x86/                            // <- Change the directory
user@linux-desktop:/home/workspace/apps/mvPropView/x86/$ ./wxPropView                    // <- Start the executable

Afterwards, several log files are generated which are listed in files.mvloglist. The log files have the file extension .mvlog. Please send these files to our support team.
