Dynamo TUI is a powerful Terminal User Interface designed for real-time monitoring of NVIDIA Dynamo deployments. Modeled after K9s, Dynamo TUI offers a seamless experience for users managing ETCD services, NATS messaging, and Prometheus metrics, all in a concise and intuitive layout.

Key Features

• ETCD Discovery: Monitor all ETCD activities dynamically, keeping track of namespaces, components, and endpoints.
• Hierarchical View: Utilize a structured three-column display to efficiently visualize the relationships between Namespaces, Components, and Endpoints.
• Health Monitoring: Access visual indicators that represent the current statuses — Ready, Provisioning, or Offline — of your services.
• NATS Monitoring: Track connection statuses, message statistics, and details about JetStream streams.
• Prometheus Metrics: Optionally scrape metrics related to TTFT, TPOT, throughput, and queue depth for deeper insights into system performance.
• Keyboard Navigation: Navigate effortlessly with Vim-style (hjkl) and arrow-key controls, enhancing the user interaction experience.

Usage Example

Dynamo TUI can be executed simply as follows:

# Basic usage (connects to local ETCD + NATS)
dynamo-tui

# With Prometheus metrics endpoint
dynamo-tui \
  --metrics-url http://localhost:9100/metrics \
  --metrics-interval 3s \
  --nats-interval 2s

# With custom ETCD/NATS endpoints
dynamo-tui \
  --etcd-endpoints http://etcd1:2379,http://etcd2:2379 \
  --nats-server nats://nats-server:4222

Dynamo TUI integrates various components ensuring a robust monitoring system:
