How to integrate Scaphandre with Grafana for energy dashboards?

Scaphandre exposes metrics via Prometheus; set up Prometheus to scrape Scaphandre's HTTP endpoint, then use Grafana to visualize the data. An example dashboard is provided at metrics.hubblo.org as shown in the README.

Does Scaphandre work on cloud instances like AWS EC2?

Scaphandre requires access to hardware power sensors, which are often not exposed in public cloud environments. It might work on bare metal cloud instances but typically not on standard virtualized ones due to sensor limitations.

Scaphandre or PowerTOP: which should I use for Linux power monitoring?

PowerTOP is focused on diagnosing power issues and tuning in real-time, while Scaphandre is designed for continuous metric collection and integration with monitoring tools. Use Scaphandre for long-term tracking and PowerTOP for optimization tasks.

What sensors does Scaphandre use to measure power consumption?

Scaphandre primarily uses Intel's Running Average Power Limit (RAPL) interfaces on supported CPUs for bare metal, and leverages hypervisor features for virtual machines. Check the documentation for specific sensor requirements and compatibility.

Can Scaphandre monitor GPU power usage?

The current features do not explicitly mention GPU monitoring; it focuses on CPU and system-level power via sensors like RAPL. GPU support may be limited or planned for future releases, so verify the roadmap for updates.

How accurate is Scaphandre compared to physical power meters?

Accuracy depends on the underlying hardware sensors; Intel RAPL provides estimates that are generally reliable but may have variances. For precise measurement, complement with physical meters where possible, as Scaphandre is software-based.

What is Scaphandre?

Scaphandre is a metrology agent designed to measure electric power and energy consumption of technology services and applications. It provides detailed metrics that help organizations and individuals understand the energy footprint of their systems, enabling data-driven decisions to improve sustainability. The agent supports various platforms and integrates with popular monitoring tools to streamline energy consumption analysis.

Target Audience

System administrators, DevOps engineers, and sustainability-focused tech teams who need to monitor and optimize the energy consumption of their infrastructure, including bare metal hosts, virtual machines, and Kubernetes clusters.

Value Proposition

Developers choose Scaphandre for its lightweight design, multi-platform support, and seamless integration with existing monitoring stacks like Prometheus. Its unique ability to expose power metrics to virtual machines breaks the opacity of cloud and virtualized environments, providing transparency for sustainability initiatives.

Overview

Use Cases

Best For

Measuring energy consumption of bare metal servers in data centers
Monitoring power usage of QEMU/KVM virtual machines from the host
Integrating energy metrics into Prometheus-based observability pipelines
Tracking sustainability metrics for Kubernetes workloads
Providing energy consumption transparency to clients in cloud or hosted services
Analyzing power efficiency of applications running on Windows or Linux systems

Not Ideal For

Projects requiring real-time power monitoring with millisecond precision
Cloud environments without exposed hardware power sensors (e.g., standard public cloud VMs)
Teams wanting a fully managed, dashboard-included energy monitoring solution out of the box
Legacy systems without modern power measurement interfaces like Intel RAPL

Pros & Cons

Pros

Lightweight Design

Scaphandre aims for near-zero overhead in resource and power consumption, as stated in its philosophy, making it suitable for continuous monitoring without significant impact on system performance.

Multi-Platform Support

It works on GNU/Linux, Windows 10/11/Server, and Kubernetes, with packages for RHEL, Debian, and Windows, ensuring broad compatibility across diverse infrastructures.

Prometheus Integration

Exposes metrics as a Prometheus HTTP exporter and supports push mode to Prometheus Push Gateway, seamlessly fitting into existing observability stacks for easy data collection.

VM Metric Transparency

Unique ability to expose power metrics from hypervisor to virtual machines, allowing VM-level energy tracking as if on bare metal, as detailed in the features for QEMU/KVM.

Cons

Early Stage Limitations

The project is in early development, as warned in the README, which means features may be incomplete, documentation sparse, and APIs subject to breaking changes.

Hardware Dependency

Relies on specific power sensors (e.g., Intel RAPL) and hypervisor features; if unsupported, measurement is impossible, limiting its applicability to modern hardware only.

Setup Complexity

Requires configuration for different outputs and platforms, with separate installation guides for Linux and Windows, which can be cumbersome and time-consuming to implement.
