一.前置环境准备

1.部署etcd集群

可以直接参考我部署K8S的文档有关于etcd集群的部署笔记。

推荐阅读:
	https://www.cnblogs.com/yinzhengjie/p/20851315

2.检查etcd集群

[root@master231 ~]# ss -ntl | grep 2379
LISTEN 0      65535     10.0.0.231:2379       0.0.0.0:*          
LISTEN 0      65535      127.0.0.1:2379       0.0.0.0:*          
[root@master231 ~]# 
[root@master231 ~]# curl  -sk --cacert /yinzhengjie/certs/etcd/etcd-ca.pem --cert /yinzhengjie/certs/etcd/etcd-server.pem --key /yinzhengjie/certs/etcd/etcd-server-key.pem https://10.0.0.231:2379/metrics | wc -l
1739
[root@master231 ~]#

3.VictoriaMetrics集群部署

推荐阅读:
	https://www.cnblogs.com/yinzhengjie/p/20942368

二.部署vmagent组件

1. vmagent概述

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。

	https://docs.victoriametrics.com/victoriametrics/sd_configs/

2.vmagent监控etcd集群实战

2.1. 下载和VictoriaMetrics同版本的vmagent

参考链接:
	https://docs.victoriametrics.com/victoriametrics/vmagent/#quick-start

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 ~]#

2.2 配置vmagent采集etcd数据

	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"
  scheme: https
  tls_config:
    ca_file: /yinzhengjie/certs/etcd/etcd-ca.pem
    cert_file: /yinzhengjie/certs/etcd/etcd-server.pem
    key_file: /yinzhengjie/certs/etcd/etcd-server-key.pem 
    insecure_skip_verify: false
  static_configs:
    - targets:
        - 10.0.0.231:2379
        - 10.0.0.232:2379
        - 10.0.0.233:2379
[root@master231 ~]#

2.3 配置vmagent的启动脚本并启动

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

[Service]
User=root
ExecStart= /usr/local/bin/vmagent-prod \
  -promscrape.config=/yinzhengjie/softwares/vmagent/vmagent.yml \
  -httpListenAddr=0.0.0.0:8429 \
  -promscrape.configCheckInterval=30s \
  -remoteWrite.url=http://10.0.0.231:8480/insert/0/prometheus/api/v1/write \
  -remoteWrite.url=http://10.0.0.232:8480/insert/0/prometheus/api/v1/write \
  -remoteWrite.url=http://10.0.0.233:8480/insert/0/prometheus/api/v1/write \
  -remoteWrite.tmpDataPath=/var/lib/vmagent-cache \
  -remoteWrite.maxDiskUsagePerURL=15GB \
  -remoteWrite.queues=4 \
  -loggerLevel=INFO

Restart=on-failure
RestartSec=5

[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 
Warning: The unit file, source configuration file or drop-ins of vmagent.service changed on disk. Run 'sys>

[root@master231 ~]#

2.4 验证vmagent是否采集到目标

[root@master231 ~]# curl http://127.0.0.1:8429/targets
job=k8s-idc-etcd-cluster (3/3 up)
	state=up, endpoint= https://10.0.0.231:2379/metrics , labels={instance="10.0.0.231:2379",job="k8s-idc-etcd-cluster"}, scrapes_total=1, scrapes_failed=0, last_scrape=11.061s ago, scrape_duration=27ms, scrape_response_size=169KiB, samples_scraped=1485, error=
	state=up, endpoint= https://10.0.0.232:2379/metrics , labels={instance="10.0.0.232:2379",job="k8s-idc-etcd-cluster"}, scrapes_total=1, scrapes_failed=0, last_scrape=10.411s ago, scrape_duration=38ms, scrape_response_size=169KiB, samples_scraped=1485, error=
	state=up, endpoint= https://10.0.0.233:2379/metrics , labels={instance="10.0.0.233:2379",job="k8s-idc-etcd-cluster"}, scrapes_total=1, scrapes_failed=0, last_scrape=21.373s ago, scrape_duration=27ms, scrape_response_size=169KiB, samples_scraped=1485, error=
[root@master231 ~]#

2.5 检查服务端是否有数据

	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

2.6 导入监控模板
