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.

A link to the topic's schema is at the top of display for easy reference.

Drilling down to a primitive value (i.e. number, string, boolean) will display that value in large text.

Diff mode

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

Click "Copy msg" to copy the current topic message to your clipboard.

Click the icon next to the message path to expand or collapse all nested fields in the displayed message.
