Grafana Dashboard 進行監控效果展現

由於 Prometheus 的頁面展現效果不是很好，通常就須要配合 Grafana 進行效果展現，Grafana更多地須要在瀏覽器進行操做

Grafana 鏈接 Prometheus 數據源(Data Source)

PS：我部署的 Grafana 是通過漢化的 7.2.0 版本（已上傳至阿里雲倉庫，公開版），對新手來講稍微友好一點，固然各位大神若是以爲不安全，或者喜歡用英文版本的，只須要去 Grafana 的官網下載部署最新版本便可。

Grafana 添加能夠監控交換機的模板，我我的修改了幾個，更貼合如今的使用環境

採用 Job 作的區分，而不是一個 Job 作的多個 target
一個 Job 對應多個 target 會有問題， Prometheus 會觸發 400 的訪問錯誤，而後咱們的監控項也沒辦法作更進一步的區分

邏輯解釋圖
json

具體模板：瀏覽器

12492 detail
10523 全部接口
12489 SNMP Device Summary
11169 顯示流量，單個交換機

示例圖：

安全

根據 10523 的模板進行的了一下簡單修改，能夠根據 Job 進行區分app
