Prometheus is an open-source metrics monitoring toolkit that uses time-series data collection, alerting rules, and PromQL querying. It's developer- and container-friendly and widely used with Kubernetes and microservices.

Prometheus is fully available in China. As an open-source project, it can be self-hosted on Chinese infrastructure without restriction, and is widely used with domestic container platforms such as Alibaba Cloud ACK or Tencent TKE.
