eBPF-powered instrumentation for Linux with near-zero overhead. Capture CPU, scheduler, I/O, network, and syscall metrics at the resolution your systems demand.
Rezolus covers the full observability workflow — from collection to analysis.
Collects system metrics via eBPF with near-zero overhead. Exposes data over HTTP for downstream consumers.
Serves Prometheus-compatible metrics with configurable histogram percentiles. Scrape-ready.
Captures high-fidelity metric snapshots to Parquet files for benchmarking and performance analysis.
Maintains a rolling ring buffer on disk. Trigger snapshots via signal or HTTP for post-incident analysis.
Interactive web dashboard with PromQL support. Explore recordings or stream live from a running agent.
AI-guided analysis tools. Query recordings with PromQL, detect anomalies, and correlate metrics.
curl -fsSL https://install.rezolus.com | bashThis adds the package repo, installs Rezolus, and starts the agent as a systemd service. Supports Debian, Ubuntu, Rocky Linux, and Amazon Linux.
rezolus view http://localhost:4241Streams live metrics from the agent into an interactive web dashboard. The agent listens on 0.0.0.0:4241, so you can also point the viewer at a remote host.
Requires Linux kernel 5.8+ and root. See full installation docs for building from source or managing services individually.
Nine sampler categories covering the full Linux performance stack.
Usage, frequency, perf counters, cache, TLB
NVIDIA and Apple Silicon metrics
Usage, vmstat, NUMA allocations
Traffic, errors, ethtool counters
Connect latency, jitter, retransmits
Latency distributions, request counts
Runqueue latency, context switches
Counts and latency by type
Self-monitoring: CPU, memory, I/O
Everything you need to deploy and operate Rezolus.
