Useful information

  • The best way to see our anomaly detection in action is to upload logs that contain real problems.
  • Result quality will improve greatly with larger file sizes and when using multiple related logs.
  • We support any log that has plain text 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.


All data is encrypted in flight and at rest and deleted after your report has been created.

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.
