Observability terms
You cannot fix what you cannot see
Running software in production without observability is flying blind. Metrics, logs, traces, dashboards, alerting, and the three pillars of observability give you the insight needed to understand what your system is actually doing under real conditions. This category covers the tools, patterns, and vocabulary of production-grade visibility.
Log Aggregation (ELK/Loki)
Log aggregation collects logs from all services into a central searchable store — ELK (Elasticsearch+Logstash+Kibana) for full-text search, Loki (Prometheus-style) for cost-efficient label-based search.
