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
Stackdriver
- Stackdriver is now branded Google Cloud Observability and cloud.google.com/stackdriver redirects to the Observability product page
- Cloud Logging charges $0.50 per GiB ingested, with only the first 50 GiB per project per month free
- Logs kept beyond 30 days cost an extra $0.01 per GiB per month on top of the ingestion charge
- Monitoring metric ingestion starts at $0.2580 per MiB, with only the first 150 MiB per billing account free
- Alerting policies are billed at $0.35 per month for each metric reference in the policy
- Uptime checks cost $0.30 per 1,000 executions and synthetic monitors $1.20 per 1,000 executions, with only 100 synthetic executions per billing account free
- Monitoring read API calls cost $0.50 per million time series returned beyond the first million per billing account
- Log volume is measured before indexing on the actual size of log entries, so verbose logging directly drives cost
