Raw Messages

Display incoming topic data in an easy-to-read collapsible JSON tree format.

Use message path syntax to specify the message path you want to inspect.

As new messages are received for a given path, the collapsible JSON tree will show just the latest data. You will be able to expand and collapse keys, and have those changes persist across playback.

Compare messages by showing additions (green), deletions (red), and changes (yellow) to their fields across 3 categories:

  • "previous message" – Compare consecutive messages for a given message path
  • "other source" - Compare messages from different data sources for a given timestamp
  • "custom" – Compare different topic messages for a given timestamp
