Google Cloud Monitoring free tier includes Always Free: all non-chargeable Google Cloud metrics, first 1M monitoring API calls/month… Not verified — our last read, on 2026-10-25, found the same terms as an earlier read we had declined to record. Compare with 42 alternatives in Monitoring.
Subtypes in Monitoring: metrics_backend — stores time-indexed measurements and serves queries over them; dashboards and alerting are built on top rather than sold as the product; uptime_check — polls a URL or host from outside your infrastructure on a fixed interval and alerts when it stops answering; it runs no code of yours; synthetic_check — runs a check you author — a scripted browser session, a multi-step API call, or an assertion on a response body — on a schedule from outside your infrastructure, and reports whether the behaviour it asserts still holds. We read that on 2026-09-01 from https://cloud.google.com/monitoring/pricing, where it says: “Execution of Monitoring Synthetic Monitors $1.20/1,000 executions” How we use this.
Google Cloud Monitoring's free tier offers Always Free: all non-chargeable Google Cloud metrics, first 1M monitoring API calls/month… We are not rating this offer today; this page's Last read note says why.
Always Free: all non-chargeable Google Cloud metrics, first 1M monitoring API calls/month. Dashboards, alerting, and uptime checks for GCP resources
No recorded pricing changes for Google Cloud Monitoring. We publish no change we refused to record, so treat the empty history as a statement about our records, not about this vendor's pricing.
How Google Cloud Monitoring compares against every one of the 42 we list, not against a selection of them. A surface with room for every member of a tied set may rotate their order. A surface with room for only some of them names none of them, because which ones it named would be the claim, and a claim seeded on the date is not the one we serve tomorrow. How we decide this.
