Audit Trails

ASTRA provides two levels of audit trail to independently record all operator actions that create, modify, or delete electronic records. Each entry in the audit trail is time-stamped, and records the operator performing the actions, as well as the computer where the actions are performed. In the screen shot below, the general view of the system log is displayed, along with the option to display the experiment log.

System log

The system log is always associated with the database where the data is stored. This audit trail cannot be separated from the data associated with it. The system log records actions such as:

  • Logins, login attempts, and logouts
  • Data creation, modification, and deletion
  • Database connections and disconnections
  • Import and export of data from the database

Experiment log

Each experiment has a separate log that records all actions within the experiment that affect the data. The experiment log is always with the experiment, and cannot be reset. The experiment log records actions such as:

  • Changes to instrument configuration settings
  • Changes to analysis methods
  • Collection of data
  • Electronic signatures executed to the experiment
  • Changes in presentation methods
