Grafana官网地址https://grafana.com/Grafana使你能够把来自不同数据源比如Elasticsearch,

Prometheus,

influxDB等多样的数据以绚丽的图标展示出来。

它也能基于你的metrics数据发出告警。

当一个告警状态改变时它能通知你通过emailslack或者其他途径。

Grafana是一个开源的度量分析与可视化套件纯JavaScript开发的前端工具通过访问库如InfluxDB展示自定义报表、显示图表等。

它的UI十分灵活有丰富的插件和模板功能强大。

一般用在时序数据的监控方面。

Prometheus安装我们使用docker进行安装。

首先拉去镜像#

拉取docker镜像

prom/prometheus准备配置文件prometheus.yml${host1}、${host2}为变量例如可以替换为localhost:8080scrape_configs:

job_name:

采集服务的地址设置成Springboot应用所在服务器的具体地址static_configs:-

targets:

[${host1},${host2}]启动--log.leveldebug日志以debug输出--storage.tsdb.retention.time3d数据保留3天--config.file/etc/prometheus/prometheus.yml容器里面的默认路径docker

run

/root/docker-images/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml

--name

--storage.tsdb.retention.time3d

--config.file/etc/prometheus/prometheus.yml或者启动脚本docker

run

/root/docker-images/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml

--name

--config.file/etc/prometheus/prometheus.yml启动成功后访问地址http://${ip}:9090/页面展示3.2

Grafana安装拉去镜像docker

grafana/grafana访问地址http://localhost:3000账号admin密码admin页面展示3.3

Sources--

URL注意Name必须为首字母大写Prometheus不能全写成小写的prometheus。

因为Prometheus和Grafana都是docker安装所以url需要写外网地址。

2新建

DashboardCreate

Dashboard配置title、description配置Data

Source选择指标保存3.4

模板套用Grafana提供了许多优秀的模板可以网页https://grafana.com/grafana/dashboards
