Wave Autoscale Agent

Description

Wave Autoscale Agent is a high-performance metrics collection agent designed for Kubernetes and OpenShift clusters. Written in Rust, it provides node-level performance data and resource utilization metrics for intelligent autoscaling decisions.

The agent runs as a DaemonSet on each Kubernetes/OpenShift node, collecting real-time container metrics via cAdvisor including CPU usage, memory consumption, disk I/O, network traffic, and pressure stall information (PSI). It aggregates and processes these metrics to enable the Wave Autoscale platform to make data-driven scaling decisions.


Key Features:
- High-performance Rust implementation for minimal overhead
- Real-time container and node metrics collection
- Integration with cAdvisor for comprehensive container metrics
- Support for CPU, memory, disk I/O, network, and PSI metrics
- OpenShift-compatible security context (non-root, arbitrary UIDs)
- Built on Red Hat UBI 9 Minimal
- Multi-architecture support (amd64 and arm64)
- Includes health check endpoints for Kubernetes liveness/readiness probes

Technical Specifications:
- Language: Rust 1.89.0
- Base Image: Red Hat UBI 9 Minimal
- User: Non-root (UID 1001)
- License: Check repository for license information
- Health Check: Process-based monitoring via pgrep

This agent is part of the Wave Autoscale platform ecosystem and works in conjunction with the Wave Autoscale cAdvisor container to provide comprehensive autoscaling capabilities for containerized workloads.
