通过 Prometheus 获取 Kubernetes 中 Pod 资源(CPU/MEM/GPU)消耗信息

<p> <span style=”font-size:16px;”></span><span style=”font-size:20px;”><strong>一、prometheus简介</strong></span> </p> <p> <span style=”font-size:16px;”><strong> </strong></span> </p> <p> <strong> Prometheus是一个开源的系统监控和告警系统,现在已经加入到CNCF基金会,成为继k8s之后第二个在CNCF维护管理的项目,在kubernetes容器管理系统,通常会搭配prometheus进行监控prometheus支持多种exporter采集数据,还支持通过pushgateway进行数据上报,<span

style=”text-align:left;”> <strong> <span style=”font-size:16px;color:#323232;”></span> </strong> </p> <strong> </strong> <p style=”text-align:left;”> <strong> <span style=”font-size:16px;color:#323232;”>1.Prometheus Server: 用于收集和存储时间序列数据。</span> </strong> </p> <strong> </strong> <p style=”text-align:left;”> <strong> <span style=”font-size:16px;color:#323232;”>2.Client Library: 客户端库,检测应用程序代码,当Prometheus抓取实例的HTTP端点时,客户端库会将所有跟踪的metrics指标的当前状态发送到prometheus server端。</span> </strong> </p> <strong> </strong> <p style=”text-align:left;”> <strong> <span style=”font-size:16px;color:#323232;”>3.Exporters: prometheus支持多种exporter,通过exporter可以采集metrics数据,然后发送到prometheus server端</span> </strong> </p> <strong> </strong> <p style=”text-align:left;”> <strong> <span style=”font-size:16px;color:#323232;”>4.Alertmanager: 从 Prometheus server 端接收到 alerts 后,会进行去重,分组,并路由到相应的接收方,发出报警,常见的接收方式有:电子邮件,微信,钉钉, slack等。</span> </strong> </p> <strong> </strong> <p style=”text-align:left;”> <strong> <span style=”font-size:16px;color:#323232;”>5.Grafana:监控仪表盘</span> </strong> </p> <strong> </strong> <p style=”text-align:left;”> <strong> <span style=”font-size:16px;color:#323232;”>6.pushgateway: 各个目标主机可上报数据到pushgatewy,然后prometheus server统一从pushgateway拉取数据。</span> </strong> </p> <strong> </strong> <p>
