Data transformers convert raw cluster data in the relational database into a format usable for reporting and analysis.
There are logging levels that determine the detail of messages that the data transformers record in the log files. In decreasing level of detail, these levels are ALL (all messages), TRACE, DEBUG, INFO, WARN, ERROR, FATAL, and OFF (no messages).
By default, the data transformers log messages of INFO level or higher (that is, all INFO, WARN, ERROR, and FATAL messages).
The data transformer log files are located in the datatransformer subdirectory of your Platform Analytics server log directory:
Data transformers are installed as scheduled tasks. Change the schedule of data transformer services as you would for scheduled tasks (see Scheduled tasks).
