Data Storage

PAtools provides the following methods to save your test run data:

  • Cyclic measurement (default): Stores data acquired with different frequencies in different files.
  • One shot measurement: Manually triggers the recording of a single record set that is saved in a separate file.
  • Post-mortem dump: Automatically writes to disk in specific error situations. You may also trigger post-mortem dump manually.
  • Circular buffer: Saves data in a ring buffer for a longer time range than post-mortem dump.
  • Long term measurement: Records slowly changing values.

The following sections provide a description of the concepts of these different storage options. The usage and the configuration are explained in separate chapters.
