(9.0+) Statistics API logging
Statistics API generates the following log files:
- StatisticsService_YYYYMMDD_HHMMSS
The log file name contains the date and time since the last restart of Statistics API service.
Statistics API's yaml file is used to configure the following:
- Where the active files are located
- What log level to write logs
Statistics API's yaml File Location
This can be located on each server in the registry
- HKEY_LOCAL_MACHINE\SOFTWARE\Virtual Hold
- InstallationLocation
The folder InstallationLocation is appended with \Dashboard
example = C:\Program Files (x86)\Virtual Hold Technology\Dashboard
The name of the yaml file is: vht_stats_api-config.yml

When troubleshooting an issue, be sure to set the log level to the appropriate level to capture all the necessary information.
