Overview
Thanos is a set of components that can be composed into a highly available metric system with unlimited storage capacity, which can be added seamlessly on top of existing Prometheus deployments.
Thanos leverages the Prometheus 2.0 storage format to cost-efficiently store historical metric data in any object storage while retaining fast query latencies. Additionally, it provides a global query view across all Prometheus installations and can merge data from Prometheus HA pairs on the fly.
Concretely the aims of the project are:
- Global query view of metrics.
- Unlimited retention of metrics.
- High availability of components, including Prometheus.
Architecture Overview
Getting Started
Features
- Global querying view across all connected Prometheus servers
- Deduplication and merging of metrics collected from Prometheus HA pairs
- Seamless integration with existing Prometheus setups
- Any object storage as its only, optional dependency
- Downsampling historical data for massive query speedup
- Cross-cluster federation
- Fault-tolerant query routing
- Simple gRPC "Store API" for unified data access across all metric data
- Easy integration points for custom metric providers
Thanos Philosophy
The philosophy of Thanos and our community is borrowing much from UNIX philosophy and the golang programming language.
- Each sub command should do one thing and do it well
- eg. thanos query proxies incoming calls to known store API endpoints merging the result
- Write components that work together
- e.g. blocks should be stored in native prometheus format
- Make it easy to read, write, and, run components
- e.g. reduce complexity in system design and implementation
Releases
Master should be stable and usable. Every commit to master builds docker image named master-<data>-<sha>.
We also perform minor releases every 6 weeks. During that, we build tarballs for major platforms and docker image.
See release process docs for details.
Contributing
Contributions are very welcome! See our CONTRIBUTING.md for more information.
Community
Thanos is an open source project and we value and welcome new contributors and members of the community. Here are ways to get in touch with the community:
- Slack: #thanos
- Issue Tracker: GitHub Issues
