Grafana部署
一 Grafana介绍
官方文档：https://grafana.com/docs/
Grafana是一款基于go语音开发的通用可视化工具，支持从多种不同的数据源加载并展示数据，可作为其数据源的部分存储系统如下所示：
- TSDB：Prometheus、IfluxDB、OpenTSDB和Graphit
- 日志和文档存储：Loki和ElasticchSearch
- 分布式请求跟踪：Zipkin、Jaeger和Tempo
- SQL DB：mysql、PostgreSQL
二 Grafana基础
- 默认监听于TCP协议的3000端口，支持集成其它认证服务，且能够通过/metrics输出内建指标；
- 几个基本概念：
- 数据源（Data Source）：提供用于展示的数据的存储系统
- 仪表盘（Dashboard）：组织和管理数据的可视化面板（Panel）
- 团队和用户：提供了面向企业组织层级的管理能力
- 默认账号密码：admin/admim
