Prometheus是一个开源的系统监控和报警系统现在已经加入到CNCF基金会成为继k8s之后第二个在CNCF托管的项目在kubernetes容器管理系统中通常会搭配prometheus进行监控同时也支持多种exporter采集数据还支持pushgateway进行数据上报Prometheus性能足够支撑上万台规模的集群。

EOF修改配置文件prometheus.yml
前面部分基本没改动沿用默认配置。
参数作用scrape_interval默认抓取间隔, 15秒向目标抓取一次数据scrape_configs这个配置是表示在这个配置内的时间序例每一条都会自动添加上这个{job_name:“prometheus”}的标签 - job_name: ‘prometheus’job_name默认抓取间隔, 15秒向目标抓取一次数据scrape_interval监控名称相当于分组组名之类 可手动自定义添加static_configs配置静态获取地址与targets配合使用file_sd_configs引用外部获取地址与files配合使用files外部获取地址文件指定外部IP地址需要以json格式。 此方法优点适合大集群规模可以根据hosts文件批量生成json文件。可以直接添加IP地址不用修改主配置不用重启prometheus
最终配置文件如下
# my global config
global:scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.# scrape_timeout is set to the global default (10s).# Alertmanager configuration

systemctl enable prometheusnode exporter Exporter是Prometheus的指标数据收集组件。它负责从目标Jobs收集数据并把收集到的数据转换为Prometheus支持的时序数据格式。 和传统的指标数据收集组件不同的是他只负责收集并不向Server端发送数据而是等待Prometheus Server 主动抓取.
node-exporter 默认的抓取url地址http://ip:9100/metrics
另外如果因为环境原因网络不可达的场景Prometheus可以使用Pushgateway 这个组件推送node-exporter的指标数据到远端Prometheus
node-exporter用于采集node的运行指标包括node的cpu、load、filesystem、meminfo、network等基础监控指标类似于zabbix监控系统的的zabbix-agent
node-export由Prometheus官方提供、维护属于监控指标收集类UNIX内核操作系统的必备的exporter。

graphite_exporter
Graphite 来收集度量标准Grafana 则用于构建仪表板首先需要配置 Spark 以将 metrics 报告到 Graphite。
prometheus 提供了一个插件graphite_exporter可以将 Graphite metrics 进行转化并写入 Prometheus (本文的方式)。
graphite_exporter 接收数据端口为9109
