Useful information

  • It will work best with logs that contain real problems (otherwise you might not see anomalies)
  • Result quality improves with larger file sizes and multiple related logs.
  • We support any plain text log with a timestamp at or near the beginning of most lines.
  • You may use this tool as many times as you want. You'll also be offered free access to our full service.

How does it work?

Machine learning structures each event and builds a “dictionary” of event types. This lets us reliably learn normal patterns and detect anomalies. Anomaly factors include: first occurrence of an event, change in frequency or periodicity and correlations across files or streams. You can read more about it here.
