Overview
Troubleshooting information aims to provide resolutions to specific issues that can occur while using or configuring the VFC to WFE Metadata Integrator.
Configuration
See VFC to WFE Metadata Integrator Configuration Guide for more information on the configuration process.
Log files
The VFC to WFE Metadata Integrator offers extensive log configuration functionality, which can be amended to provide more information when troubleshooting.
The Integrator writes its log to the following file:
where INSTALLDIR is the installation directory of the Integrator, and YYYYMMDD represents the current date. The log file path is configured in the Serilog section of the appsettings.Production.json file.
A new log file is created both at set time intervals and when the log file size exceeds the value configured in the appsettings.Production file. The default configuration defines the time interval as every day, and the log file size as 100 MB.
The previous log file gets added to a .tar.gz file. The location where the archived log files are saved can be configured in the Internal section of the appsettings.Production file. By default, they are saved in a folder called Archived that is placed within the Logs folder. By omitting the parameter to configure the archived folder path, the archived log files are placed in the Logs folder, next to the active log file.
You can configure the archived log file compression level and the number of archived log files that are kept. When the maximum number of archived log files is reached, the oldest archive file is removed.
Refer to the Configuration Guide for more information on logging configuration.
If you require more detailed logging for troubleshooting, you can change the logging settings for the Integrator by editing the appsettings.Production configuration file.
Section | Parameter | Description | Default value |
|---|---|---|---|
Serilog | MinimumLevel | Log level setting of the application. Only increase the log level temporarily when you are doing troubleshooting. Leaving the log level on Debug/Verbose level can have an adverse effect on system performance which could lead to data loss in critical situations. | Information |
Serilog | fileSizeLimitBytes | Maximum size of a log file in bytes. If a file reaches the file size limit, the next log message is written into the next file. | 104857600 |

Troubleshooting steps
- Verify that the appsettings.Production.json file has been created.
- Verify that the Log folder and a log file in it have been created.
- Verify that the configured parameters in the WFE, VFC, Secrets, and DataMapping sections of the appsettings.Production.json file are accurate.
