Store

## **Storage Type Selection:**

- Local Storage

- Alibaba Cloud Storage (OSS)

- AWS S3 Storage

- ~~Huawei Cloud Storage~~ (OBS)  removed in version V3.3.3.0.

- ~~Minio Storage~~  removed in version V3.3.3.0.

**Storage content includes system applications and cover image data.**

**Notes:**

1. Once the application is uploaded, the storage method cannot be changed, so please choose carefully.

2. When using Minio, Alibaba, Huawei, or AWS S3 storage in the standalone version, modify the configuration file "LarkXR_Standlone\larkxr-center\application.properties" by setting pxy.host.as-admin-render-mixed-node to false to trigger synchronization.

3. When switching from local storage to object storage in the standalone version, restart the admin and agent services.

**The default storage method is local storage:**

- Stored on the central management node.

- Applications are by default stored in the "appli" folder under the deployment directory of the central node. If you need to change the application storage location, select the application program save path in the LarkXR central service manager's configuration management.

**Alibaba Cloud OSS Storage Configuration:**

- Modify the protocol, bucket name, endpoint, Key, and Secret in \larkxr-center\application.properties.

## **Saving VR Monitoring Data:**

Choosing to enable saving will store VR usage data in the database (lark_metrics) and retain data within the specified **VR monitoring data retention period**.

> **Description of lark_metrics fields:**

- client_render_latency: Client rendering latency

- decode_latency: Decoding latency

- transport_latency: Transmission latency

- encode_latency: Encoding latency

- server_render_latency1, server_render_latency2: Not used

- cmd_upload_latency: Command upload latency

- total_latency: Total latency

- feel_latency: Not used

- black_edge_degree: Black edge degree

- client_fps: Client FPS

- server_fps: Server FPS

- rtt: Round-Trip Time (network round-trip delay simulated using application-layer data)

- packet_rate, packets_lost_in_second, total_sent: Not used

- sent_rate: Throughput rate (sending rate)

- frame_rate: Frame rate

- resolution_ratio: Resolution ratio

## **Saving Server Utilization Data:**

Choosing to save will generate a CSV file in the "ServerUsageData" drive under the deployment directory, with the file being split every day at 1 a.m.

Note: Please be cautious when enabling data saving, as it may lead to storage wastage.
