Micromegas is an observability system designed to provide unified insights into complex applications. It allows you to collect and analyze logs, metrics, and traces in a single, scalable database. Our goal is to help you spend less time reproducing bugs and more time understanding and improving your software's quality and performance.
- Empower developers with comprehensive insights, eliminating time-consuming bug reproduction.
- Quantify issue frequency and severity to allow better priority management.
- Provide detailed traces based on high-frequency telemetry to enable a deep understanding of every issue.
- 🚀 Unified Observability: Store and query logs, metrics, and traces together to get a complete picture of your application's behavior.
- ⚡ Low-Overhead Instrumentation: Client-side instrumentation adds minimal overhead, averaging just 20 ns per event in the calling thread.
- 🌊 High-Frequency Data Collection: Built to handle up to 100,000 events per second from a single instrumented process.
- ☁️ Scalable & Cloud-Native: The backend is designed to scale horizontally, capable of ingesting data from millions of concurrent processes using object storage (S3) and PostgreSQL.
- 💰 Cost-Efficient by Design: Keep costs low with tail sampling and on-demand ETL. Raw data is stored cheaply and only processed when you need to query it.
- 🔍 Powerful SQL Interface: Query your data using a powerful and familiar SQL interface, powered by Apache DataFusion and accessible via Apache Arrow FlightSQL.
Micromegas consists of several key components:
- Instrumentation Libraries: Lightweight libraries for your applications (available in Rust and Unreal Engine) to send telemetry data.
- Ingestion Service (
telemetry-ingestion-srv): A scalable service that receives telemetry data and writes it to blob storage. - Analytics Service (
flight-sql-srv): A DataFusion-powered service that exposes a FlightSQL endpoint for running queries against your data. - PostgreSQL Database: Stores metadata about processes, streams, and data blocks, keeping the object storage indexable and fast to query.
- Object Storage (S3/GCS): Stores all raw telemetry payloads and materialized query results in Parquet format.
Unlike traditional observability platforms with opaque and often escalating costs, Micromegas offers a transparent and orders of magnitude more efficient solution. With Micromegas, you can afford to record billions of events without relying heavily on sampling, gaining a complete and accurate picture of your systems. By leveraging your own cloud infrastructure, Micromegas drastically reduces your observability spend, especially at scale.
