gpu-hot

GPU Hot is a lightweight, web-based real-time monitoring dashboard for NVIDIA GPUs. It runs as a self-hosted Docker container and supports single-machine or multi-node cluster monitoring with sub-second metric updates.

What gpu-hot is

FastAPI backend with NVML GPU monitoring and WebSocket streaming; frontend uses Chart.js for historical visualization. Supports NVIDIA SMI fallback for older GPUs, multi-node hub aggregation, and per-process metrics collection.

Quickstart

Get the gpu-hot source

Clone the repository and explore it locally.

terminalbash

Best use cases

MLOps cluster monitoring

Monitor GPU utilization, temperature, power, and memory across 1–100+ GPUs in training clusters. Hub mode aggregates metrics from multiple nodes into a single dashboard without requiring GPU hardware on the hub machine.

Development and debugging

Real-time per-process GPU metrics help identify which applications consume GPU resources. Useful during model development and optimization cycles where rapid feedback on resource usage is critical.

DevOps and infrastructure health checks

Self-hosted deployment avoids external dependencies; Docker integration simplifies rollout to existing infrastructure. Lightweight polling design (paused when idle) minimizes overhead in production environments.

Implementation considerations

  • NVIDIA Container Toolkit required; verify driver compatibility and GPU access inside containers before deployment.
  • Process monitoring requires `--pid=host` and `--init` flags, which grant container access to host process namespace—evaluate in security-sensitive environments.
  • Multi-node hub mode relies on HTTP connectivity between nodes; ensure firewall rules allow port 1312 and monitor network latency for aggregation delay.
  • Metrics are stored in-memory only; implement external scraping (e.g., Prometheus `/api/gpu-data` endpoint) if long-term retention is needed.
  • UPDATE_INTERVAL tuning affects CPU usage during idle periods; default 0.5s is aggressive for many-GPU setups; increase if CPU cost is a concern.

When to avoid it — and what to weigh

  • Requires managed SaaS monitoring — GPU Hot is self-hosted only. If your organization requires vendor-managed monitoring with SLAs, incident escalation, or integration with managed observability stacks, evaluate hosted alternatives.
  • Non-NVIDIA GPU environments — Designed for NVIDIA GPUs only (via NVML/nvidia-smi). AMD, Intel, or other accelerator types are not supported.
  • Critical alerting and automation — No native alerting, webhooks, or integration with incident management systems. Not suitable as the primary monitoring tool if you need automatic escalation or remediation.
  • Complex data retention and compliance — In-memory historical data only; no built-in persistence layer or compliance-focused audit logging. Projects with retention or regulatory reporting requirements should extend with a metrics backend.

Security considerations

Process monitoring via `--pid=host` exposes container to host process information; limit deployment to trusted networks and assess impact in multi-tenant environments. No authentication or TLS for dashboard or WebSocket; place behind reverse proxy with auth if exposed outside internal networks. In-memory metrics include process names and GPU usage, which may be considered sensitive in shared infrastructure.

Alternatives to consider

Grafana + Prometheus (with NVIDIA DCGM exporter)

Enterprise-grade stack with persistent storage, alerting, and multi-datasource dashboards. Higher operational complexity but better for large-scale and compliance-driven deployments.

NVIDIA DCGM + Kubernetes monitoring

Native NVIDIA solution integrated with Kubernetes; better job-scheduler correlation. Requires more infrastructure and NVIDIA licensing in some tiers.

Commercial platforms (Wiz, OctoML, Lambda Labs)

Managed SaaS with alerting, team access, and cloud-native integrations. Trade-off: external dependency, no self-hosting, vendor lock-in risk.

gpu-hot FAQ

Can I use GPU Hot in a Kubernetes cluster?
Not natively. Deploy via DaemonSet or StatefulSet; hub mode requires a separate Pod. Lacks Kubernetes service discovery, so NODE_URLS must be manually configured or templated.
Does GPU Hot persist metrics to disk?
No. Historical data is in-memory only during the session. For long-term retention, scrape the `/api/gpu-data` endpoint with Prometheus, InfluxDB, or similar.
What is the overhead of GPU Hot on GPU training jobs?
Negligible. NVML polling is CPU-bound and pauses when no dashboard clients are connected. Typical idle CPU ~0%; impact on GPU memory or training is minimal.
How do I secure the dashboard if deployed on a public network?
GPU Hot has no built-in auth. Use a reverse proxy (nginx, Caddy) with TLS and basic auth, or restrict access via firewall rules to internal networks only.
