FAQ

What log formats are supported?

The analyzer handles common formats such as syslog, JSON log lines, and Postfix/SMTP mail logs. Paste raw lines and it will parse the fields it recognizes.

What does the structured report include?

You get anomaly detection, a key-event timeline, and a list of suggested action items prioritized by severity, so you know what to fix first.

Is my log data sent to a server?

No. Analysis runs locally in your browser, so sensitive log contents stay on your machine.

Can it help with non-SMTP server logs?

Yes. While it is tuned for mail logs, it also parses general syslog and JSON lines to surface anomalies and timelines.
