Use this tool to check a Marshall SDK or firmware log against known-good reference traces without reviewing it line by line. You can give it:
  • A log file (.txt or .log)
  • An Excel certification workbook, where each sheet is treated as one test
  • Log text pasted directly, on the Paste log text tab
The tool runs it through the same nine checkpoints Nayax uses when reviewing your certification tests: boot handshake, reader state, vend and authorization flow, and session close. The Checkpoints & Scenario Tags page documents each one.
Everything runs locally in your browser. Log files never leave your machine, except for the “Learn more” links, which open Nayax’s documentation.

Setting the timing threshold

The timing anomaly threshold sets how large a gap between two consecutive events in the log the tool flags as unusual. Gaps appear in the log as +Xms. The default is 15000 milliseconds, which is 15 seconds. Raise the threshold when a test includes an intentional long wait, such as a 24-hour idle test, a session timeout, or a stress test. For a one-hour wait, set it to 3600000. If you leave the default in place, the tool reports a failure on timing that is really the test working as designed.

​
Reading the results

Each log or sheet gets a verdict badge:
  • ALL CHECKS PASSED: every checkpoint passed, no action needed.
  • REVIEW RECOMMENDED: at least one checkpoint raised a warning worth a manual look. Not necessarily a bug.
  • FAILED CHECKS FOUND: at least one checkpoint failed outright and needs attention.
Below the badge, a trace strip shows one dot per checkpoint, in the same colors:
  • Green: pass
  • Amber: warning
  • Red: fail
  • Hollow gray: not applicable to that log
For any checkpoint that isn’t green, a “Suggested fix” box explains the likely cause and links to the relevant documentation. An evidence line shows the exact log line the checkpoint was based on.
