Notification Feed

Notification Feed is the live log viewer: severity-filtered messages from /rosout, with optional timestamps and node names. Use it during long autonomous runs, anytime you want the robot's own log voice visible alongside the dashboard. For raw topic data including non-log messages, Topic Log (Pro) is the broader inspector. For your own publish events, Publish Log.

Point Log Topic at /rosout, which auto-fills Message Type to rcl_interfaces/msg/Log. Set Min Severity to Warning so the feed only surfaces what needs attention during a long Nav2 run, then drop it to Info while debugging a specific failure. Leave Auto-scroll on for hands-off monitoring, off when you want to scroll back through what just happened without the view jumping.

• Min Severityfilters messages after they've already reached /rosout; it doesn't touch the node's own logger level. If you set it to Debug and still see nothing, raise the verbosity on the robot, not in Tinca.
• The subscription is capped at 20 Hz regardless of Max Entries; a node logging faster than that has entries dropped before severity filtering ever sees them.
• Switching Log Topicwipes the buffer immediately, so swap topics only when you're done reading, not mid-incident.
