Loki is a log aggregation system inspired by Prometheus. It does not index the contents of the logs, but rather a set of labels for each log stream. Compared to other log aggregation systems, Loki: - does not do full text indexing on logs - indexes and groups log streams using the same labels as Prometheus, allowing to seamlessly switch between metrics and logs using the same labels - has native support in Grafana 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 Additionally 2 other components are provided: - logcli to run LoqQL queries against a Loki server - loki-canary to audit the log capturing performance of Loki

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

Additionally 2 other components are provided:

|
- logcli to run LoqQL queries against a Loki server
