Tag logs

A tag log is a file of recorded tag values. Profinity can replay it onto the live tags later, so that rules, alerts, derived tags, and dashboards react as they did when the data was captured. The TAG File Logger or TAG SFTP Logger (Secure Shell File Transfer Protocol) writes the log, and TAG LOG REPLAY under TAG UTILITIES plays it back.

  • Log tags to a file: record the tags in selected collections to a CSV or JSON Lines file.
  • Replay a tag log: play a recorded log back onto your live tags, which requires Replay tag changes.
