Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

CloudWatch

  • The free tier covers 5 GB of log ingestion and 10 custom metrics a month, after which log ingestion is $0.50 per GB from 5 to 30 GB
  • Custom metrics are $0.30 each for the first 10,000, so instrumenting broadly gets expensive before volume discounts apply
  • Each custom dashboard beyond the free three is $3 a month
  • Alarms are billed at $0.10 per alarm metric a month, with high-resolution alarms costing more
  • Log storage beyond the free 5 GB is $0.03 per GB per month on top of the ingestion charge

Graylog

  • Graylog Enterprise starts at $15,000 per year and Graylog Security at $18,000 per year, priced by daily volume or annual consumption
  • Correlation engine, scheduled and custom reports, compliance reports and teams management are Enterprise-only
  • Data tiering across hot, warm and archive storage is an Enterprise feature, not available in Graylog Open
  • Graylog Open carries community support only; professional support requires a paid edition
  • UEBA anomaly detection, Sigma rules, MITRE ATT&CK alignment and SOAR automation are limited to Graylog Security
