Today, at the ongoing KubeCon 2019, Grafana Labs, an open source analytics and monitoring solution provider, announced that Loki version 1.0 is generally available for production use. Loki is an open source logging platform that provides developers with an easy-to-use, highly efficient and cost-effective approach to log aggregation.

The Loki project was first introduced at KubeCon Seattle in 2018. Before the official launch, this project was started inside of Grafana Labs and was internally used to monitor all of Grafana Labs’ infrastructure. It helped ingest around 1.5TB/10 billion log lines a day.

Released under the Apache 2.0 license, the Loki tool is optimized for Grafana, Kubernetes, and Prometheus. Just within a year, the project has more than 1,000 contributions from 137 contributors and also has nearly 8,000 stars on GitHub.

With Loki 1.0, users can instantaneously switch between metrics and logs, preserving context and reducing MTTR. By storing compressed, unstructured logs and only indexing metadata, Loki is cost-effective and simple to operate by design. It includes a set of components that can be composed into a fully-featured logging stack. Grafana Cloud offers a high-performance, hosted Loki service that allows users to store all logs together in a single place with usage-based pricing.


Loki’s design is inspired by Prometheus, the open source monitoring solution for the cloud-native ecosystem, as it offers a Prometheus-like query language called LogQL to further integrate with the cloud-native ecosystem.

Tom Wilkie, VP of Product at Grafana Labs, said, “Grafana Labs is proud to have created Loki and fostered the development of the project, building first-class support for Loki into Grafana and ensuring customers receive the support and features they need.” He further added, “We are committed to delivering an open and composable observability platform, of which Loki is a key component, and continue to rely on the power of open source and our community to enhance observability into application and infrastructure.

Grafana Labs also offers enterprise services and support for Loki, which includes:

  • Support and training from Loki maintainers and experts
  • 24 x 7 x 365 coverage from the geographically distributed Grafana team
  • Per-node pricing that scales with deployment
