// VERDICT
Reach for Graylog when log collection, search and alerting is your core need and you want a self-hostable, open-source-rooted platform. Skip it when you need metrics/traces/APM (Datadog/New Relic) or just dashboards (Grafana).
Best for
Centralised log management and analysis - an open-source/freemium platform to collect, search and alert on logs at scale, with a security (SIEM) lean.
Avoid when
You want full-stack metrics/traces (APM), a pure visualisation layer, or an all-in-one commercial observability suite.

// BEST FOR
- Centralising logs from many services for search and analysis
- Open-source-rooted, self-hostable log management
- Alerting and stream rules on log patterns
- Security/SIEM-style log use cases
- Reproducing bugs from centralised, searchable logs
- Scaling log ingestion beyond grep-on-a-box
// AVOID WHEN
- You need metrics and traces (APM), not just logs
- You want a pure dashboard/visualisation layer (Grafana)
- An all-in-one commercial observability suite is preferred
- You don't want to run log-ingestion infrastructure
- Single-pillar error tracking is all you need (Sentry)
- You want zero-setup SaaS only
// QUICK START
Stand up Graylog and its backing store -> configure inputs / log shippers from
your services -> define streams and alerts -> search centralised logs to
reproduce bugs and watch release health.// ALTERNATIVES TO CONSIDER
// FEATURES
- Centralised log ingestion via Beats, Syslog, GELF, and Kafka
- Stream-based routing and processing rules
- Powerful search with saved queries and dashboards
- Alert framework with notification channels
- Pipeline language for parsing and enrichment
// PROS
- Open core — self-hostable without hidden licence costs
- Stream and pipeline model maps cleanly to multi-tenant logs
- Mature and stable, used in regulated environments
- Lighter operational footprint than full ELK for small teams
// CONS
- UI dated compared to Kibana and Grafana
- Enterprise features (audit log, archiving) gated behind paid tier
- Smaller community than Elastic and Grafana ecosystems
