一覽

Elastic Stack (ELK: Elasticsearch, Logstash, Kibana) is the industry standard for observability. Ingest logs from 1000s of servers, search them instantly, visualize metrics (CPU, memory, latency), trace requests across microservices. Critical for production systems: detect anomalies, debug performance issues, forensics on failures. Learning takes 4-6 weeks; mastery (pipeline optimization, advanced queries, architecture) takes 3-6 months. Specialists earn $110-170K+ because every cloud company relies on Elastic Stack; downtime from observability failure is costly ($10K/min for SaaS).

什麼是 Elastic Stack Observability

Elastic Stack (formerly ELK: Elasticsearch, Logstash, Kibana) is a platform for collecting, storing, and analyzing logs, metrics, and traces from applications and infrastructure. Elasticsearch is a search and analytics engine. Logstash parses and transforms logs. Kibana is the visualization and alerting UI. Workflow: (1) Applications log events. (2) Beats agents collect and forward. (3) Logstash parses (extract timestamp, severity, error message). (4) Elasticsearch indexes. (5) Kibana visualizes and alerts.

❓ 常見問題

Why Elastic over Splunk?
Elastic = open source + cheap (self-hosted). Splunk = SaaS, expensive ($10-15K/month). Elastic = 80% of Splunk features at 20% cost. Trade-off: Elastic requires DevOps effort (self-hosting). Splunk = managed, pay more.
How do I ingest logs from 100 servers?
Use Beats agents (lightweight, installed on each server). Forward logs to Elasticsearch via Logstash (parsing, enrichment, routing). Or direct to Elasticsearch if pre-formatted. Ingest millions of logs/sec.
What's the difference between logs and metrics?
Logs = text messages (error: connection refused). Metrics = numbers (CPU: 75%, Memory: 2GB). Use logs for debugging. Use metrics for alerting (if CPU > 90%, page oncall). Ingest both.
How do I query millions of logs efficiently?
Elasticsearch inverted index. Query scans million docs in 100ms (fast). But million × million queries = slow. Use date filters, cardinality limits, aggregations instead of individual searches.
How do I set up alerting?
Kibana alerting: define condition (error rate > 5%), threshold (trigger if true for 5 min), action (send Slack message, page Opsgenie). Runs continuously, detects issues faster than humans.
