ELI5 — The Vibe Check

Real Talk
Log aggregation systems collect, parse, index, and store log data from distributed sources into a centralized platform. Tools like the ELK stack (Elasticsearch, Logstash, Kibana), Grafana Loki, Datadog Logs, and Splunk provide search, filtering, alerting, and visualization capabilities.
