Logging

observability
description
Centralized log aggregation, indexing, and search for structured and
unstructured log streams emitted by applications, infrastructure, and
platform components. Core concerns include log shipping (Fluentd,
Fluent Bit, Vector), retention policies, cardinality, and cost.
Popular implementations: the ELK/EFK stack (Elasticsearch/OpenSearch +
Logstash/Fluentd + Kibana), Grafana Loki (label-based log aggregation
paired with Grafana dashboards), Splunk (enterprise), and managed
offerings (AWS CloudWatch Logs, Datadog Logs, Papertrail). Structured
JSON logging is preferred over plain text for machine-readable queries.
Closely integrated with the Metrics and Tracing stack parts.
