Loki is a horizontally-scalable, highly-available, multi-tenant log aggregation system inspired by Prometheus.
It is designed to be very cost effective and easy to operate. It does not index the contents of the logs, but rather a set of labels for each log stream.
This is free and open source software.
A Loki-based logging stack consists of 3 components:
- promtail is the agent, responsible for gathering logs and sending them to Loki.
- loki is the main server, responsible for storing logs and processing queries.
- Grafana for querying and displaying the logs.
- Stores compressed, unstructured logs and only indexing metadata, Loki is simple to operate and cheaper to run. Send logs in any format, from any source, using a wide array of clients.
- 100% persistence to object storage.
- Build metrics and generate alerts from your log lines.
- Indexes and groups log streams using the same labels you’re already using with Prometheus, enabling you to seamlessly switch between metrics and logs using the same labels that you’re already using with Prometheus.
- Tail your logs in realtime to see the logs as they come into the system, update the logs after every certain time, view logs for a particular date, etc.
- Works well for storing Kubernetes Pod logs. Metadata such as Pod labels is automatically scraped and indexed.
- Native support in Grafana (needs Grafana v6.0).
