Log Aggregation

Definitions

1. The practice of collecting, centralizing, and indexing log output from many distributed services and hosts into a single searchable system. Tools like the ELK stack (Elasticsearch, Logstash, Kibana), Grafana Loki, Datadog, and Splunk are common log aggregation platforms.

   In plain English: Gathering logs from many different servers and applications into one place so you can search through all of them at once.

   Example: "Without log aggregation, debugging a request that crosses five microservices means SSH-ing into five boxes and grepping five different log files."
