安裝 PVE (Proxmox Virtual Environment) Agent 的方式

返回 Ubuntu 20.04 / CentOS7 安裝 LibreNMS 程序
這是 SNMP Extend
PVE 8.2

設定程序

在 PVE 主機內安裝

apt install libpve-apiclient-perl sudo
wget https://raw.githubusercontent.com/librenms/librenms-agent/master/agent-local/proxmox -O /usr/local/bin/proxmox
chmod +x /usr/local/bin/proxmox

驗證是否 proxmox 可以執行成功

/usr/local/bin/proxmox

如果成功, 訊息大概如下

<<<app-proxmox>>>

152/net0/94636075/77614449/pve-ms

修改 sudo 設定檔

/etc/sudoers.d/proxmox

# Cmnd alias specification
Debian-snmp     ALL=(ALL) NOPASSWD: /usr/local/bin/proxmox

修改 snmpd 設定

vi /etc/snmp/snmpd.conf

:
extend proxmox /usr/bin/sudo -S /usr/local/bin/proxmox

重新啟動 snmpd

systemctl restart snmpd

如果 LibreNMS 無法正確呈現虛擬機網路流量圖, 出現 Error Drawing Graph 的訊息如下, 可能和 rrd 內 proxmox 目錄權限有關, 可以進入 LibreNMS 主機內執行 chown 修改目錄正確權限, Exp. 若正確權限應該為 librenms:librenms

chown -R librenms:librenms /opt/librenms/rrd/proxmox/

以下 Agent 方式

設定啟用 Proxmox graphs 服務
/opt/librenms/config.php
```
:
$config['enable_proxmox'] = 1;
```

到 PVE 主機內安裝 LibreNMS-agent

apt-get install sudo
wget https://raw.githubusercontent.com/librenms/librenms-agent/master/agent-local/proxmox -O /usr/local/bin/proxmox
chmod +x /usr/local/bin/proxmox

root@nuc:~# wget https://raw.githubusercontent.com/librenms/librenms-agent/master/agent-local/proxmox -O /usr/local/bin/proxmox
root@nuc:~# chmod +x /usr/local/bin/proxmox
root@nuc:~# /usr/local/bin/proxmox
<<<app-proxmox>>>

106/net0/214723565/83403063/ct-lintsaiweb

到 PVE 主機內修改 sudo 與 snmpd 設定檔並重起 snmpd

/etc/sudoers

:
# Cmnd alias specification
Debian-snmp     ALL=(ALL) NOPASSWD: /usr/local/bin/proxmox
:

/etc/snmp/snmpd.conf

:
extend proxmox /usr/bin/sudo /usr/local/bin/proxmox

systemctl restart snmpd

可以到 LibreNMS 主機內透過 snmpwalk 來驗證是否 PVE 主機內的 snmpd 設定正確 Exp.

snmpwalk -v2c -c public 192.168.11.251 NET-SNMP-EXTEND-MIB::nsExtendOutput2Table

[root@ct-librenms ~]# snmpwalk -v2c -c public 192.168.11.251 NET-SNMP-EXTEND-MIB::nsExtendOutput2Table
NET-SNMP-EXTEND-MIB::nsExtendOutLine."proxmox".1 = STRING: <<<app-proxmox>>>
NET-SNMP-EXTEND-MIB::nsExtendOutLine."proxmox".2 = STRING: ichiayi

到 LibreNMS PVE 主機項目啟用 Application - Proxmox
再來就可以在 PVE 主機項目看到 app 的分頁
