====== 安裝 SMART Agent 的方式 ======
  * 返回 [[tech:librenms]]

  * 這是 SNMP Extend

  * 至被監控主機內安裝 <code sh>
wget https://github.com/librenms/librenms-agent/raw/master/snmp/smart -O /etc/snmp/smart
chmod +x /etc/snmp/smart
</code>
  * 編輯 /etc/snmp/smart.config 內容類似以下<file>
#This is a comment
cache=/var/cache/smart
smartctl=/usr/bin/env smartctl
useSN=0
sda
sdb
</file>
<note>
  * 可透過 <code sh>fdisk -l | grep "Disk /dev"</code> 查詢目前主機內的硬碟
  * 再透過 <code sh>smartctl -a /dev/sda</code> 方式來確認所列出來的硬碟是否可支援 SMART
</note>
  * 確認 smart 可以正確執行<code sh>
/etc/snmp/smart</code> 如果正確執行應該可以看到類似的訊息<cli>
sda,null,null,0,null,null,null,null,null,42,0,null,null,0,null,null,0,0,0,0,0,0,0,0,323
sdb,null,null,null,0,0,0,36,36,null,0,0,0,null,null,0,0,0,0,0,0,0,0,17598
</cli>
  * 如果系統沒有安裝 sudo 套件就需要先安裝<cli>
apt install sudo
</cli>
  * 新增 sudoers 的 smart 設定<code>
vi /etc/sudoers.d/smart</code><file>
# Cmnd alias specification
Debian-snmp     ALL=(ALL) NOPASSWD: /etc/snmp/smart
:
</file><cli>
chmod 440 /etc/sudoers.d/smart
</cli>
  * 修改 snmpd 設定<code>
vi /etc/snmp/snmpd.conf</code><file>
:
extend smart /usr/bin/sudo -S /etc/snmp/smart
</file>重新啟動 snmpd <code sh>
systemctl restart snmpd
</code>
