vmagent是VictoriaMetrics生态的采集代理，支持多种部署方式:
- 1.二进制裸机部署
- 2.Docker 容器部署
- 3.K8s VM Operator CRD 托管部署
vmagent替代Prometheus Server做指标抓取、去重、转发，支持多远端写入（VM、Prometheus RemoteWrite）。
使用`-promscrape.config`指定 Prometheus 配置文件的路径（通常位于 `/etc/prometheus/prometheus.yml`）。
vmagent 不支持 Prometheus 配置文件的某些部分，因此您可能需要删除这些部分或使用 `-promscrape.config.strictParse=false` 命令行标志运行 vmagent。

如上图所示，根据官方提示，我们可以下载对应的软件包，这个软件包建议和你的VictoriaMetrics集群版本要一致。
具体部署方式如下:
1.下载和VM同版本vmagent
[root@master231 ~]# wget https://github.com/VictoriaMetrics/VictoriaMetrics/releases/download/v1.146.0/vmutils-linux-amd64-v1.146.0.tar.gz
2.解压软件包
[root@master231 ~]# tar tf vmutils-linux-amd64-v1.146.0.tar.gz
vmagent-prod
vmalert-prod
vmalert-tool-prod
vmauth-prod
vmbackup-prod
vmrestore-prod
vmctl-prod
[root@master231 ~]#
[root@master231 ~]#
[root@master231 ~]# tar xf vmutils-linux-amd64-v1.146.0.tar.gz -C /usr/local/bin/
[root@master231 ~]#
3.检查版本
[root@master231 ~]# vmagent-prod --version
vmagent-20260619-123257-tags-v1.146.0-0-g4d9901fbf4
[root@master231 ~]#
1.创建配置文件目录
[root@master231 ~]# mkdir /yinzhengjie/softwares/vmagent
[root@master231 ~]#
2.编辑配置文件
[root@master231 ~]# cat /yinzhengjie/softwares/vmagent/vmagent.yml
global:
scrape_interval: 30s
scrape_timeout: 10s
scrape_configs:
- job_name: "k8s-idc-etcd-cluster"

[root@master231 ~]#
1.编写启动脚本
[root@master231 ~]# cat /usr/lib/systemd/system/vmagent.service
[Unit]
Description=https://www.cnblogs.com/yinzhengjie

-remoteWrite.queues=4 \
-loggerLevel=INFO

[Install]
WantedBy=multi-user.target
[root@master231 ~]#
2.启动服务
[root@master231 ~]# systemctl daemon-reload
[root@master231 ~]#
[root@master231 ~]# systemctl enable --now vmagent.service
Created symlink /etc/systemd/system/multi-user.target.wants/vmagent.service → /usr/lib/systemd/system/vmagent.service.
[root@master231 ~]#
3.检查监听端口
[root@master231 ~]# ss -ntl | grep 8429
LISTEN 0 65535 0.0.0.0:8429 0.0.0.0:*
[root@master231 ~]#
[root@master231 ~]# systemctl status vmagent.service

1.去 vmselect 查询指标（验证写入集群成功）
http://10.0.0.231:8481/select/0/vmui
http://10.0.0.232:8481/select/0/vmui
http://10.0.0.233:8481/select/0/vmui
2.查看图形
如上图所示。我们可以输出测试的语句: etcd_server_has_leader
