无人驾驶车辆运行中要记录的经度,纬度,速度,方向,旁边物体的距离等等。每时每刻都要将数据记录下来做分析。
某一个地区的各车辆的行驶轨迹数据
传统证券行业实时交易数据
实时运维监控数据等
2 时间序列数据特点性能好
存储成本低:高效的压缩算法,节省存储空间,有效降低IO
3 后台启动Prometheus./prometheus --config.file=prometheus.yml &
测试:执行之后还是会弹出提示信息,但是回车或ctrl+c后,该进程并没有被杀死,还是可以访问Prometheus的

,点Status --》点Targets --》可以看到只监控了本机
查看监控的目标(界面如下):
其默认只监控了本机一台,注意查看时,localhost需要修改为linux的主机地址
图例说明
- State:表示当前机器的运行状态,UP代表运行,DOWN代表没有运行
默认页面:
输入关键字进行查看,这个的输入会有提示的
在远程linux主机(被监控端agent1)上安装node_exporter组件。其主要作用就是帮助Prometheus收集数据
官方下载地址: https://prometheus.io/download/
链接:https://pan.baidu.com/s/1ABbfa2VuPLYM_KabYMSeJQ
提取码:2g1f
第一步:将下载的node上传到想要收集的Linux机器上
收集每一种信息想要不同的node组件
第二步:解压到对应的目录中
实际操作(一般是解压到usr/local目录下,我这个是解压过了,就步修改了)
[root@localhost ~]# mv node_exporter-0.16.0.linux-amd64.tar.gz /opt/ [root@localhost ~]# [root@localhost opt]# tar -zxvf node_exporter-0.16.0.linux-amd64.tar.gz node_exporter-0.16.0.linux-amd64/ node_exporter-0.16.0.linux-amd64/LICENSE node_exporter-0.16.0.linux-amd64/node_exporter node_exporter-0.16.0.linux-amd64/NOTICE [root@localhost opt]# ls apache-maven-3.5.4 kibana-7.6.1-linux-x86_64 apache-maven-3.5.4-bin.tar.gz maven containerd node_exporter-0.16.0.linux-amd64 elasticsearch-7.6.1 node_exporter-0.16.0.linux-amd64.tar.gz elasticsearch-analysis-ik-7.4.0 prometheus elasticsearch-analysis-ik-7.4.0.zip rh filebeat [root@localhost opt]# mv node_exporter-0.16.0.linux-amd64 node_export [root@localhost opt]# ls apache-maven-3.5.4 kibana-7.6.1-linux-x86_64 apache-maven-3.5.4-bin.tar.gz maven containerd node_export elasticsearch-7.6.1 node_exporter-0.16.0.linux-amd64.tar.gz elasticsearch-analysis-ik-7.4.0 prometheus elasticsearch-analysis-ik-7.4.0.zip rh filebeat [root@localhost opt]# cd node_export/ [root@localhost node_export]# ls LICENSE node_exporter NOTICE [root@localhost node_export]#
第三步:在安装目录下运行node_exporter,收集Linux主机信息
nohup ./node_exporter &
nohup:代表会永久的运行下去,除非我们将其停止
第四步:查看是否运行,通过端口查看:lsof -i:9100
lsof -i:9100
执行流程
[root@localhost node_export]# nohup ./node_exporter & [1] 67601 [root@localhost node_export]# nohup: 忽略输入并把输出追加到"nohup.out" [root@localhost node_export]# lsof -i:9100 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME node_expo 67601 root 3u IPv6 629243 0t0 TCP *:jetdirect (LISTEN) [root@localhost node_export]#
第五步:通过浏览器访问http://被监控端IP:9100/metrics就可以查看到node_exporter在被监控端收集的监控信息
第二步:修改配置信息第一步中,安装了node_exporter,只是安装,并没有使Prometheus收集到这些信息
回到prometheus服务器的配置文件里添加被监控机器的配置段,在配置文件的最后添加如下内容
- job_name: 'agent1'
static_config:
- targets: ['192.168.126.132:9100']
第三步:重启服务
[root@localhost prometheus-2.6.1.linux-amd64]# pkill prometheus [root@localhost prometheus-2.6.1.linux-amd64]# level=warn ts=2022-02-08T09:35:14.287987247Z caller=main.go:405 msg="Received SIGTERM, exiting gracefully..." level=info ts=2022-02-08T09:35:14.288075426Z caller=main.go:430 msg="Stopping scrape discovery manager..." level=info ts=2022-02-08T09:35:14.288098231Z caller=main.go:444 msg="Stopping notify discovery manager..." level=info ts=2022-02-08T09:35:14.288105588Z caller=main.go:466 msg="Stopping scrape manager..." level=info ts=2022-02-08T09:35:14.288130775Z caller=main.go:440 msg="Notify discovery manager stopped" level=info ts=2022-02-08T09:35:14.288115221Z caller=main.go:426 msg="Scrape discovery manager stopped" level=info ts=2022-02-08T09:35:14.288145369Z caller=manager.go:664 component="rule manager" msg="Stopping rule manager..." level=info ts=2022-02-08T09:35:14.288154592Z caller=manager.go:670 component="rule manager" msg="Rule manager stopped" level=info ts=2022-02-08T09:35:14.288156181Z caller=main.go:460 msg="Scrape manager stopped" level=info ts=2022-02-08T09:35:14.28898856Z caller=notifier.go:521 component=notifier msg="Stopping notification manager..." level=info ts=2022-02-08T09:35:14.289016013Z caller=main.go:615 msg="Notifier manager stopped" level=info ts=2022-02-08T09:35:14.289145291Z caller=main.go:627 msg="See you next time!" [1]+ 完成 ./prometheus --config.file=prometheus.yml
确认端口没有进程占用

回到web管理界面 --》点Status --》点Targets --》可以看到多了一台监控目标
额,我这个是在配置信息的时候,地址写错了,这里便不改了,各位注意就是了
流程与5差不多,就是想要安装不同的node,总结根据需求进行安装即可
