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.) Note 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

Object	Value
`nodes_to_publish`	Publishes node metadata for specified nodes (that appear prior to this node in the PIpeline). `none` : Disable publishing. `all` : Publish all supported nodes . (Default) `specific` : Publish only the specified nodes using `node_ids_to_publish`
`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`
`trigger`	Publish specific node metadata just when this condition evaluates to true. Uses default triggers if not specified. Use with `nodes_to_publish` set to `specific`. Optional. Ex. `nodes.annotate_line_counter1.lines.line1.dir1_objects_crossed_delta > 0`
`objects_to_publish`	Publishes object attributes depending on object's properties meeting the specified criteria. `none`: Disable object attribute publishing. `node_related`: Publish attributes for objects related to Specific Node (above) `pattern_matched_objects` :Publish attributes for objects specified by Metadata pattern `type_matched_objects` :Publish attributes for objects matching a specific type.
`object_match_patterns`	Publish object metadata for objects specified by this pattern. Use with `pattern_matched_objects` Ex. `nodes...*.cur_dir1_objects`
`objects_only_new_updated`	Publish only New/Updated Objects If true, only publishes new/updated objects.
`object_types`	Object types to publish (unset means process all). Use with `type_matched_objects`. Ex. `car`,`person`,`car.red`
`object_track_lifespan`	Object Track Lifespan (Frames) Number of frames for which an object is tracked to prevent duplicate reporting when the New/Updated option is set.
`event_type`	Metrics Event type to publish. This can be used to filter/count specific events in the Dashboard. Ex. `car_stop_and_go`
`event_trigger`	Publish a Metrics Event just when this condition evaluates to true. Ex. `nodes.annotate_line_counter1.lines.line1.dir1_objects_crossed_delta > 0`
`metrics_tag`	Tag published metrics with this tag to make it easier to filter or group them in the Dashboard.
`interval`	Min Interval (seconds) Minimum time between consecutive publish actions
`use_stream_clock`	Use timestamps from Stream? If true, reports timestamps from the stream. Enable to report correct time information when processing files.
