  • Memory stack operations,
  • Application events.

Before the system evernts are written to ETL file, they are buffered and then saved to log and compressed in binary format to save space. Report files can take a large amount of space, so it is adviced to track the amount of available space on disk to where they are written. Tracerpt command can be used to parse event trace logs to search for relevant information using various filters.
