[Prometheus]Add custom grafana template to Prometheus-stack

template location

• kube-prometheus-stack/templates/grafana/dashboards-1.14/
• 나의 경우 alertmanager-overview.yaml 파일을 복사해서 사용했다.

cp kube-prometheus-stack/templates/grafana/dashboards-1.14/alertmanager-overview.yaml kube-prometheus-stack/templates/grafana/dashboards-1.14/cloudwatch-exporter.yaml

Export grafana dashboard

Variables에 datasource 추가

Save JSON to file

cloudwatch-exporter.json

0.03MB

Create new template

• 아래는 복사해온 template에서 dashboard이름을 “alertmanager-overview” → “cloudwatch-exporter” 으로 변경한 것이다.
• data: 에 위에서 추출한 json 파일의 내용을 입력한다.
