Grafana 使用

Grafana 是一套开源的分析监视平台，支持 Graphite, InfluxDB, OpenTSDB, Prometheus, Elasticsearch, CloudWatch 等数据源，其 UI 非常漂亮且高度定制化。

这是 Prometheus web console 不具备的，在上一节中我已经说明了选择它的原因。

版本说明

Mac version 4.3.2

安装和运行程序

这里我使用 brew 安装，命令为

brew update
brew install grafana

当安装成功后，你可以使用默认配置启动程序

grafana-server -homepath /usr/local/Cellar/grafana/4.3.2/share/grafana/

如果顺利，你将看到如下日志

此时，你可以打开页面 http://localhost:3000，访问 Grafana 的 web 界面。
