Configuring error logging
The error log, error_log.csv, is a comma-separated values (CSV) file.If you use the default error logging extension, ErrorLoggingExt, you can set the logging level to the following settings:
*Information
The error log records messages that trace iHub behavior.
*Warning
The error log records warnings. The errors do not necessarily affect the operation of iHub.
*Severe
The error log records errors that can result in iHub failure if you do not correct them.
*Fatal
The error log records critical errors from which iHub cannot recover and that can result in failure.
