sysutils/loki 3.5.3 OpenBSD

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
