Rust profiler for CPU, memory, SQL, HTTP, and async performance, with Prometheus and Grafana support.

No outside reports on file

Hotpath is a legitimate profiling tool, but its performance data is sensitive and should be protected; ensure Prometheus endpoints are only accessible to authorized services and networks.

Based on public adoption and transparency signals as of Oct 21, 2026. Our opinion, not a code audit or security guarantee.

About Hotpath

Hotpath is a Rust-based profiler that measures CPU, memory, SQL, HTTP, and async performance in applications. It sends performance data to Prometheus and can display it in Grafana dashboards. It helps developers find slow code and bottlenecks.

Who it’s for

Rust developers who want detailed performance monitoring and profiling data for their applications. Teams using Prometheus and Grafana for observability.

Alternatives

pprof (Google's profiling library, supports multiple languages)
Flamegraph (Rust profiling and visualization tool)
perf (Linux built-in CPU profiler)
Grafana Pyroscope (observability platform for continuous profiling)

Setup

Check these steps against the project’s own instructions before running anything.

Follow the project's README. The project is Rust-based, so installation and integration steps depend on your application setup and will be documented in the repository at https://github.com/hotpath-rs/hotpath (opens external site).

Why this grade

CC — Moderate risk signals

Signal-based grade (3/7 points): well starred on GitHub, public source code. This reflects adoption and transparency, not a code review.

Popularity and upkeep

These are public popularity signals, not a maintenance check. Look at the repository’s commit history and open issues.

Risks to watch for

Sensitive performance data: Profiling data may reveal application internals, database queries, or API call patterns that could be exploited if exposed.
Network access to Prometheus: The profiler connects to Prometheus endpoints and could be tricked into sending data to attacker-controlled servers if configuration is modified.
Indirect code injection: If profiler output is used in web dashboards without proper sanitization, malicious query names or slow-path labels could inject code.
Resource overhead: Profiling adds CPU and memory overhead; misconfigured sampling rates could degrade application performance or cause denial of service.

How to lower the risk

Least-privilege permissions

Run the profiler with minimal privileges needed to monitor target processes.
Restrict Prometheus write access to the profiler service only.

Network isolation

Keep Prometheus and Grafana on private networks, not exposed to the internet.
Use firewall rules to limit which hosts can reach monitoring endpoints.

Monitoring

Log all profiler connections and configuration changes.
Alert if profiling data is sent to unexpected destinations.

Red flags to watch for

Changes to Prometheus endpoint URLs or credentials.
Unusual spikes in profiling data or resource usage from the profiler itself.
Profiler accessing files or systems outside the target application.
