HLSDASH

HLSDASH is an open-source platform for monitoring, visualization, and management of large-scale IT environments. It provides a high-level view by aggregating metrics, logs, and traces from multiple data sources into a single dashboard, while supporting drill-down to individual services and components. The project emphasizes reliability, scalability, and ease of integration with existing observability stacks.

HLSDASH stands for High-Level System Dashboard. It originated as an internal monitoring tool at a cloud services provider and was released as an open-source project in 2020. The project is maintained by a community-driven governance model with core maintainers and contributor guidelines.

Key features include templated dashboards, role-based access control, alert rules, and built-in anomaly detection. It offers connectors for Prometheus, OpenTelemetry, Elasticsearch, InfluxDB, and other cloud-native data sources. The platform provides a RESTful API and a declarative dashboard language for reproducibility, along with export/import capabilities and a plugin architecture to extend data sources and visualizations.

Architecture-wise, HLSDASH comprises a data ingestion layer, a query and aggregation service, and a rendering front-end. It uses a modular plugin system to add data sources and visualizations, supports multi-tenant deployments, and can run on-premises or in the cloud. The design emphasizes scalability and interoperability with common observability tools.

Reception and usage: The platform has been adopted by enterprises and service providers seeking unified visibility across hybrid environments. It emphasizes compatibility with popular observability tools and can be integrated into existing CI/CD pipelines and incident-management workflows.

Limitations: Deployment complexity, performance considerations for very large metric sets, and dependency on stable data sources can pose challenges. Communities recommend careful resource planning and incremental rollout.
