By default, Proxus stores all ingested data in its internal high-performance Time-Series database (ClickHouse). However, you often need to stream this data simultaneously to other systems, such as a cloud platform (AWS, Azure), a corporate data lake, or another MQTT broker. For more information about the internal database, see ClickHouse Integration.
This is managed via Targets.
The Data Splitter Architecture
A "Target" is a destination for your telemetry. You can attach multiple targets to a single device. Proxus acts as a high-speed data splitter, sending a copy of the normalized data to all active targets in parallel.
- SYSTEM INTERNAL DB: The default target. Used for internal dashboards, alerts, and historical analysis.
- External Targets: Custom destinations like Kafka, InfluxDB, or AWS IoT Core.
Transport Strategy
Each target defines a Transport Strategy that controls how data is forwarded:
- Pass Through: Sends every data point to the target (best for full fidelity storage).
- On Change: Sends only values that changed (reduces bandwidth for high-frequency tags).
Use Pass Through for complete historical archives and On Change when you want to minimize outbound traffic.
Configuring Targets
You manage targets on a per-device basis. This allows you to control exactly which data leaves the edge, optimizing bandwidth and storage costs. For more about device configuration, see Add Device and Device Profiles.
Navigate to Device
Open Data Management > Devices and select the device you want to configure.
Open Targets Tab
Click on the Targets tab in the detail view. You will see the SYSTEM INTERNAL DB listed by default.
Link a Target Profile
- Click the Link button in the toolbar.
- Select a pre-configured Target Profile from the list (e.g., "Corporate InfluxDB" or "Cloud MQTT Bridge").
- Click OK.
Before linking a target to a device, you must first define its connection details (URL, Credentials, Strategy) in the Integrations section of the platform. For more information about target configuration, see Integrations Overview.
Verify Connection
The device will immediately begin streaming data to the new target. Check the Status column in the grid to ensure the connection is healthy.
The Store & Forward guarantee applies to all targets independently. If your cloud connection drops but the internal DB is fine, the Edge Gateway will buffer the cloud data locally. Once the connection is restored, it flushes the buffer automatically without losing a single data point. For more details about this architecture, see Stateless Edge Architecture.
