Grafana Loki Documentation
Like Prometheus, but for logs!
Grafana Loki is a set of components that can be composed into a fully featured logging stack.
Unlike other logging systems, Loki is built around the idea of only indexing metadata about your logs: labels (just like Prometheus labels). Log data itself is then compressed and stored in chunks in object stores such as S3 or GCS, or even locally on the filesystem. A small index and highly compressed chunks simplifies the operation and significantly lowers the cost of Loki.
Note: You can use Grafana Cloud to avoid installing, maintaining, and scaling your own instance of Grafana Loki. The free forever plan includes 50GB of free logs. Create an account to get started.
