pve 集群的监控

在创建一个Proxmox创建一个 api用户类型
并设置权限

pveum roleadd Monitoring
pveum rolemod Monitoring --privs Sys.Modify,VM.Monitor,Sys.Audit,Datastore.Audit,VM.Audit

创建一个叫monitoring的用户并设置密码

pveum useradd monitoring@pve --comment "The ICINGA 2 monitoring user"
pveum useradd prometheus@pve --comment "The prometheus monitoring user"
pveum passwd prometheus@pve
pveum passwd monitoring@pve

给用户指派角色

pveum aclmod / -user monitoring@pve -role Monitoring
pveum aclmod / -user prometheus@pve -role Monitoring

当然，这些也都可以在pve图形操作

然后安装pve的Prometheus客户端

首先安装pip客户端

apt-get install -y python-pip

然后安装pve的Prometheus客户端

pip install prometheus-pve-exporter

找一下安装到哪里去了？

root@proxmox01s:~# whereis pve_exporter
pve_exporter: /usr/local/bin/pve_exporter

添加到pve 的systemd 里面，用于开机启动

cat <<EOF> /etc/systemd/system/prometheus-pve-exporter.service
[Unit]
Description=Prometheus exporter for Proxmox VE
Documentation=https://github.com/znerol/prometheus-pve-exporter

[Service]
Restart=always
User=prometheus@pve
#ExecStart=/opt/prometheus-pve-exporter/bin/pve_exporter /etc/prometheus/pve.yml
ExecStart= /usr/local/bin/pve_exporter /etc/prometheus/pve.yml


[Install]
WantedBy=multi-user.target
EOF

上面注释掉的是如果你才用python的虚拟环境的话，一般会装到opt这个目录去
启动服务的用户，要和创建的一致
User=prometheus@pve
然后创建pve.yml文件

default:
    user: prometheus@pve
    password: yourpassword
    verify_ssl: false

密码是刚刚你创建的密码
启动prometheus-pve-exporter，
如非特别指定，默认跑到9221

systemctl daemon-reload
systemctl start prometheus-pve-exporter

然后配置，根据你的 PVE exporter在哪里运行，决定推或者拉的方式，使用不同的配置文件。

Example config for PVE exporter running on PVE node:

scrape_configs:
  - job_name: 'pve'
    static_configs:
      - targets:
        - 192.168.1.2:9221  # Proxmox VE node with PVE exporter.
        - 192.168.1.3:9221  # Proxmox VE node with PVE exporter.
    metrics_path: /pve
    params:
      module: [default]

Example config for PVE exporter running on Prometheus host:

scrape_configs:
  - job_name: 'pve'
    static_configs:
      - targets:
        - 192.168.1.2  # Proxmox VE node.
        - 192.168.1.3  # Proxmox VE node.
    metrics_path: /pve
    params:
      module: [default]
    relabel_configs:
      - source_labels: [__address__]
        target_label: __param_target
      - source_labels: [__param_target]
        target_label: instance
      - target_label: __address__
        replacement: 127.0.0.1:9221  # PVE exporter.
