(三) Prometheus 监控思科交换机---Grafana 进行监控效果展现
Grafana Dashboard 进行监控效果展现
- 由于 Prometheus 的页面展现效果不是很好，通常就须要配合 Grafana 进行效果展现，Grafana更多地须要在浏览器进行操做
-
Prometheus 监控思科交换机文档完整地址：https://blog.51cto.com/liujingyu/category9.htmlhtml
- 总体逻辑效果图
Grafana 链接 Prometheus 数据源(Data Source)
- PS：我部署的 Grafana 是通过汉化的 7.2.0 版本（已上传至阿里云仓库，公开版），对新手来讲稍微友好一点，固然各位大神若是以为不安全，或者喜欢用英文版本的，只须要去 Grafana 的官网下载部署最新版本便可。
Grafana 添加能够监控交换机的模板，我我的修改了几个，更贴合如今的使用环境
- 采用 Job 作的区分，而不是一个 Job 作的多个 target
- 一个 Job 对应多个 target 会有问题， Prometheus 会触发 400 的访问错误，而后咱们的监控项也没办法作更进一步的区分
逻辑解释图json
具体模板：浏览器
- 12492 detail
- 10523 全部接口
- 12489 SNMP Device Summary
- 11169 显示流量，单个交换机
示例图：安全
根据 10523 的模板进行的了一下简单修改，能够根据 Job 进行区分app
