Graylog
Pros
- + Graylog Open is free with no volume restrictions — self-hosted logging without per-GB billing
- + Full data ownership and residency control; runs on your own hardware or private cloud
- + Long track record (project since 2009) with active community and solid documentation
- + Commercial editions let you stay on the same deployment as you grow into SIEM use cases
Cons
- - SSPL license is source-available, not OSI open source — restricts offering it as a service
- - Enterprise/Security/Cloud pricing is quote-based with no public calculator
- - Self-hosting carries real operational load: OpenSearch/Data Node, MongoDB, index and retention management
- - Audit logging and SIEM content sit in paid editions, not Open
Elastic Observability
Pros
- + One search engine for logs, metrics, traces, synthetics and RUM with a single query language
- + Open source again (AGPLv3/SSPL/ELv2 since August 2024) — self-managed deployments are free
- + Cheap volume-tiered ingest on serverless: from $0.07/GB (Logs Essentials) with $0.017/GB-month retention
- + Data tiers and searchable snapshots keep long retention affordable while staying queryable
- + 50+ cloud regions on AWS, Google Cloud and Azure with FedRAMP High, SOC 2 Type II, ISO 27001, HIPAA, PCI DSS
Cons
- - Genuine learning curve: query DSL, index lifecycle, shard and mapping decisions
- - Self-managed operation (JVM tuning, upgrades, snapshots) is a real operational project
- - Meters run on enriched pre-compression volumes and "as low as" rates are volume-tiered — bills surprise the unprepared
- - Support priced as a percentage of spend (5% Gold, 10% Platinum, 15% Enterprise on top of consumption)
