Overview

This node is publishes pipeline metadata to Lumeo Dashboards periodically or when a trigger condition is met. You can use it for reporting and dashboards.

How to Use

This node can publish 3 types of metadata to the Lumeo Dashboard.

Metadata Type	Description	When to Use
Node Metadata	This includes Node-specific metadata such as Line Counter Node's line crossing metadata or Occupancy Monitor node's occupancy metadata. Refer to Node's documentation for information on what metadata is published to the Dashboard.	Use it to publish Node-specific stats such as line crossings, or occupancy numbers.
Object Attributes Metadata	This includes object types and object attributes that are added to an object by AI Model Node or specific Recognition nodes.	Use it to capture and display attributes (such as license plate numbers, vehicle types, barcode values, colors, etc.) \n \nNote that if you are just trying to count object attributes you are better served by using the Node Metadata instead of publishing Object Attributes.
Event Metadata	This publishes an event to the Dashboard every time specific Trigger Conditions are met.	Use it to publish counts of custom events that are not already being published by Node metadata -- such as a car making an illegal left turn.

Dashboard Setup

After deploying a Pipeline with this node, create a Lumeo Dashboards and add a Data widget to it to visualize the data.

Properties

Property	Description	Type	Default	Required
`nodes_to_publish`	Controls which node metadata to publish. Options: - `none`: Disable publishing - `all`: Publish all supported nodes - `specific`: Publish only specified nodes	enum	`all`	No
`node_ids_to_publish`	Publish metadata for the specified Node ID, when `nodes_to_publish` is set to `specific`. Ex. `annotate_line_counter1`, `annotate_queue1`	node	null	Yes
`trigger`	Publish node metadata when this condition evaluates to true. Uses default triggers if not specified. Example: `nodes.annotate_line_counter1.lines.line1.dir1_objects_crossed_delta > 0`	trigger-condition	null	No
`objects_to_publish`	Controls which object metadata to publish. Options: - `none`: Disable publishing - `node_related`: Publish objects related to specified node - `pattern_matched_objects`: Publish objects matching metadata pattern - `type_matched_objects`: Publish objects of specific types	enum	`none`	No
`object_match_patterns`	Metadata patterns to match objects to publish. Only used when `objects_to_publish` is set to `pattern_matched_objects`. Example: `nodes...*.cur_dir1_objects`	metadata-list	null	No
`object_types`	Object types to publish (blank means process all). Only used when `objects_to_publish` is set to `type_matched_objects`. Example: `car`,`person`,`car.red`	model-label	null	No
`event_type`	Metrics event type to publish. Used to filter or count specific events in dashboard. Example: `car_stop_and_go`	string	null	No
`event_trigger`	Publish metrics event when this condition evaluates to true. Example: `nodes.annotate_line_counter1.lines.line1.dir1_objects_crossed_delta > 0`	trigger-condition	null	No
`metrics_tag`	Tag to apply to published metrics for filtering/grouping in dashboard. Example: `mymetric`	string	null	No
`objects_only_new_updated`	If true, only publish objects when first seen. If false, publish both new and updated objects	bool	true	No
`object_track_lifespan`	Number of frames to track objects to prevent duplicate reporting when new/updated option is set	number	600	No
`interval`	Minimum time in seconds between consecutive publish actions	float	5	No
`use_stream_clock`	If true, report timestamps from stream for correct timing when processing files	bool	false	No
`use_camera_as_source`	If true, report linked camera as source for camera streams and Universal bridge clips	bool	false	No
