Admin UI

Mium includes a built-in React web application for chatting with LLMs, managing settings, and administering the cluster.

Technology Stack

  • React 18 with TypeScript
  • Vite build system
  • Tailwind CSS for styling
  • Recharts for metrics visualization
  • React Router DOM for navigation

Pages

Chat (Default Home)

The primary interface for interacting with LLMs:

  • Conversational chat with tool-calling capabilities
  • Create and manage multiple chat sessions
  • Resume previous conversations with full context
  • Export conversations to PDF, PPTX, or XLSX

Routes: /, /c/:sessionId

Settings

User-level configuration pages:

  • Profile (/settings/profile): User profile management
  • LLM (/settings/llm): Configure LLM provider connection (API key, model selection)
  • Connections (/settings/connections): Manage tool connections (Ontul, Snowflake, GitHub, Slack)
  • Password (/settings/password): Change password

Admin Pages (Admin-Only)

Administrative pages visible only to admin users:

  • Dashboard (/settings/admin/dashboard): Cluster metrics and health — query throughput, latency, JVM heap usage, and worker status visualized with Recharts
  • Topology (/settings/admin/topology): Node registry and cluster topology — active Masters and Workers with node status
  • IAM (/settings/admin/iam): User, group, policy, and organization management with a visual policy editor
  • KMS (/settings/admin/kms): Key management interface for viewing and managing encryption keys

REST API

All operations available in the Admin UI are also accessible via the REST API on the Admin HTTP server (default port 8090):

  • Auth: /admin/auth/login, /admin/auth/logout, /admin/auth/refresh, /admin/auth/password
  • IAM: /admin/iam/users, /admin/iam/groups, /admin/iam/policies, /admin/iam/organizations
  • Connections: /admin/connections
  • KMS: /admin/kms
  • Chat: /admin/chat/sessions, /admin/chat/messages
  • Monitoring: /admin/monitoring/topology, /admin/monitoring/metrics, /admin/monitoring/logs

Metrics

Mium collects JVM and cluster metrics from all nodes:

  • CPU usage, heap usage, thread count (per node)
  • Node health and availability
  • Cluster-wide aggregated metrics on the Dashboard

Metrics are collected from Workers via the NIO protocol (METRICS_REQ opcode) and visualized in the Dashboard.

Real-Time Log Streaming

The Admin UI supports real-time log tailing from any node in the cluster, providing observability into Master and Worker operations without SSH access.
