prometheus学习系列三:node_exporter安装部署
node_exporter简介
node_exporter安装部署
[root@node00 ~]# cd /usr/src/ [root@node00 src]# wget https://github.com/prometheus/node_exporter/releases/download/v0.18.1/node_exporter-0.18.1.linux-amd64.tar.gz [root@node00 src]# mkdir /usr/local/exporter -pv mkdir: created directory ‘/usr/local/exporter’ [root@node00 src]# tar xf node_exporter-0.18.1.linux-amd64.tar.gz -C /usr/local/exporter/ [root@node00 src]# cd /usr/local/exporter/ [root@node00 exporter]# ls node_exporter-0.18.1.linux-amd64 [root@node00 exporter]# ln -s node_exporter-0.18.1.linux-amd64/ node_exporter
node_exporter启动
[root@node00 node_exporter]# ./node_exporter INFO[0000] Starting node_exporter (version=0.18.1, branch=HEAD, revision=3db77732e925c08f675d7404a8c46466b2ece83e) source="node_exporter.go:156" INFO[0000] Build context (go=go1.12.5, user=root@b50852a1acba, date=20190604-16:41:18) source="node_exporter.go:157" INFO[0000] Enabled collectors: source="node_exporter.go:97" # 中间输出省略 INFO[0000] Listening on :9100 source="node_exporter.go:170"
测试node_exporter
[root@node00 ~]# curl 127.0.0.1:9100/metrics
# 这里可以看到node_exporter暴露出来的数据。
配置node_exporter开机自启

# 开机自启
[root@node00 exporter]# systemctl enable node_exporter
配置prometheus采集node信息
修改配置文件
[root@node00 prometheus]# cd /usr/local/prometheus/prometheus [root@node00 prometheus]# vim prometheus.yml # 在scrape_configs中加入job node ,最终scrape_configs如下配置 scrape_configs: # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config. - job_name: 'prometheus' # metrics_path defaults to '/metrics' # scheme defaults to 'http'. static_configs: - targets: ['localhost:9090'] - job_name: "node" static_configs: - targets: - "192.168.100.10:20001" [root@node00 prometheus]# systemctl restart prometheus [root@node00 prometheus]# systemctl status prometheus
