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

Logz.io

  • SaaS-only with no self-hosting option
  • High pricing for long data retention periods, with steep cost increases for larger data volumes
  • UI can take up to 10 seconds to load
  • Geo-location data is old and inaccurate
  • Expensive for smaller companies with limited log volumes
  • Data retention limitations at 14 days may not meet compliance requirements
