+====== 安裝 PVE (Proxmox Virtual Environment) Agent 的方式  ======
+  * 返回 [[tech:librenms]]
+  * 這是 SNMP Extend
+  * PVE 8.2
+===== 設定程序 =====
+  * 在 PVE 主機內安裝 <code sh>
+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
+</code>驗證是否 proxmox 可以執行成功<code sh>
+/usr/local/bin/proxmox</code>如果成功, 訊息大概如下<cli>
+<<<app-proxmox>>>

+# Cmnd alias specification
+Debian-snmp     ALL=(ALL) NOPASSWD: /usr/local/bin/proxmox
+</code>
+  * 修改 snmpd 設定<code>
+vi /etc/snmp/snmpd.conf</code><file>
+:
+extend proxmox /usr/bin/sudo -S /usr/local/bin/proxmox
+</file>重新啟動 snmpd <code sh>
+systemctl restart snmpd
+</code>
+<note important>
+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 <code sh>
+chown -R librenms:librenms /opt/librenms/rrd/proxmox/</code> \\ {{:tech:librenms:2020071502.png}} \\ {{:tech:librenms:2020071501.png}}
+</note>
+===== 以下 Agent 方式 =====
+  - 設定啟用 Proxmox graphs 服務 <code h /opt/librenms/config.php>
+:
+$config['enable_proxmox'] = 1;
+</code>
+  - 到 PVE 主機內安裝 LibreNMS-agent <code sh>
+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</code><cli>
