English narration and permanently visible English captions accompany this recording of the October 31, 2026 Parser Studio Web UI. The examples come from published original manufacturer documentation or upstream-authored test fixtures, not from fabricated demo messages.

Practice along with the video

Keep this page open to pause or replay the demonstration while working in a second tab. Before you begin: Download all practice samples as a ZIP · Open Parser Studio

Use the source files above exactly as shown in the video. Each file contains the public documented sample events used during the recording, with source attribution and SHA-256 checksums in the ZIP bundle.

Copy the exact logs used in the video

Use the copy icon on each code block, then paste the entire content into Parser Studio. Each line is one unmodified event from the published source. Do not omit difficult events or replace values to force a passing result.

Follow the current on-screen steps

Open Auto Parser, enter manufacturer Snort and product Snort 3, then paste only the one original alert.
Click Analyze Logs and inspect the 0 of 1 log event parsed completely result. Preserve the whole alert and its unparsed regions.
Use Fix with ChatGPT and inspect the generated source-bearing prompt. Prepare ChatGPT Prompt, then Copy Prompt only after confirming that external sharing is allowed.
The new recording ends at the prompt-review stage; it does not pretend an external ChatGPT result was returned. To continue yourself, paste the model response into ChatGPT result JSON and select Check ChatGPT Result.
For a reviewable proposal, add the two independent holdout alerts under Different examples to test the fix and check Confirm test examples are different. Test before applying or downloading. The optional recipe displayed above is educational, not automatically trusted.

Expected review outcome

The original Snort alert_fast sample is not fully parsed at first. The updated video demonstrates the actual prompt preparation and privacy boundary; an external ChatGPT answer and independent holdout validation remain separate user steps. Do not treat successful source extraction or generated files as evidence of full vendor/firmware coverage, target import acceptance, or live Stellar Cyber deployment compatibility.

Recovery path

For a different log shape, keep the original records and examine the highlighted source spans, following the related workflow. Only apply additional parsing rules after different examples pass a separate regression test. Never delete failing events merely to obtain a passing total.

Original log provenance

Customer logs may include private information. Review, sanitize and manually approve any excerpt before copying it into an external ChatGPT conversation. The Auto Parser does not automatically share those logs.
