Loki: like Prometheus, but for logs.
A Loki-based logging stack consists of 3 components:
-
promtailis the agent, responsible for gathering logs and sending them to Loki. -
lokiis the main server, responsible for storing logs and processing queries. - Grafana for querying and displaying the logs.

Promtail
Promtail is an agent which ships the contents of local logs to a private Grafana Loki instance or Grafana Cloud. It is usually deployed to every machine that has applications needed to be monitored.
It primarily:
? Discovers targets
? Attaches labels to log streams
? Pushes them to the Loki instance.

Loki
- 安裝 Loki斤贰；Loki Documentation；
Loki is a horizontally-scalable, highly-available, multi-tenant log aggregation system inspired by Prometheus.
- LogQL: Log Query Language.
LogQL is Loki’s PromQL-inspired query language. Queries act as if they are a distributed grep to aggregate log sources. LogQL uses labels and operators for filtering.
