1. Scope#
这个方案是 Grafana 直接使用 CloudWatch datasource，不经过 YACE / VictoriaMetrics。
datasource:
CloudWatch
use when:
dashboard 数量少
查询频率低
不需要 PromQL / vmalert / 长期低成本保存2. Dashboard Rows#

3. Variables#
region:
CloudWatch region
InstanceId:
EC2 instance dimension
VolumeId:
EBS volume dimension4. Notes#
AWS/EC2 默认指标没有 OS memory 和 filesystem 使用率；这些面板需要 CloudWatch Agent 或 node_exporter 等额外采集。
EC2 CloudWatch 默认没有 memory / filesystem 指标。
如果要在 CloudWatch datasource 里展示 memory / disk，需要 CloudWatch Agent 写入 CWAgent namespace。
如果只看 EC2 / EBS 原生指标，CloudWatch datasource 足够。
如果要和 app metrics、node_exporter、vmalert 统一，使用 YACE + VictoriaMetrics。
