A telemetry and logging aggregation server that ingests from multiple protocols, transforms data in-flight, and emits to multiple destinations.
Cernan is a telemetry and logging aggregation server that collects data from multiple protocols, transforms it in-flight, and ships it to various aggregation services. It solves the problem of handling bursty telemetry without load shedding while providing reliable data processing.
Operations staff and application engineers who need to aggregate and transform telemetry and logs from distributed systems.
Developers choose Cernan for its reliability, multi-protocol support, and ability to perform in-flight data transformations without dropping data during traffic bursts.

Has minimal CPU and memory requirements per the README, making it suitable for resource-constrained deployments without compromising performance.
Designed to handle bursty telemetry without dropping data, ensuring reliability during traffic spikes as highlighted in the project description.
Supports multiple interfaces for telemetry and log ingestion, allowing flexible data collection from diverse sources like syslog or custom protocols.
Enables in-flight manipulation, such as converting log lines to telemetry metrics, providing real-time data processing capabilities.
The original repository is no longer maintained, forcing users to rely on a fork with potentially inconsistent updates, community support, or documentation.
Requires Rust installation and tooling, which adds setup complexity and may be unfamiliar to teams accustomed to more common languages like Go or Java.
Uses TOML files and command-line arguments for setup, which can be less intuitive than GUI-based tools and requires manual tuning for advanced features.
