3. 查看 smokeping-prober 的指标

导入面板 https://grafana.com/grafana/dashboards/11335-smoke-ping/

可以查看网络质量的指标，如丢包率、延迟等。

可以看到类似这样的面板

面板中显示的指标时丢包数量，如果要查看丢包率，可以添加一个计算指标，计算公式为：

1

3

(rate(smokeping_requests_total{host="$target"}[30s]) - rate(smokeping_response_duration_seconds_count{host="$target"}[5m]))
/
rate(smokeping_requests_total{host="$target"}[30s]) / 100
