全部Default, 而且所有requirement應該已經符合了, 直至以下Default Profile改用1分鍾, 亦改為手動不Scan

上面應該全部完成直接進入到正式Console, 我會先重新設定Sites, 把Default的都Delete, 然後重新增加Site

我有兩個Site, 把SKW & TKO都加進去

我的實例是Sophos Firewall

Name, Contact Person 和最低下的 SNMPv1 and v2c community and traps的Name都是同一個名字

Source就是Cacti的IP, 由於我有2台Cacti, 所以有2個資料

回到Cacti, 這裏的Hostname是Firewall的MGT IP, SNMP Community String是剛才在Firewall裏的名字

增加成功就能看到類似下面的資訊

SKW-Firewall (xxx.xxx.xxx.xxx)
SNMP Information
System: Linux localhost 4.14.277 #2 SMP Fri Jan 5 08:52:46 UTC 2024 x86_64
Uptime: 62945900 (7days, 6hours, 50minutes)
Hostname: xxxxxx
Location: SKW
Contact: xxxxxx

然後按右上角的 Create Graphs for this Device, 把你需要Monitor的都勾選, Select a Graph Type to Create選擇In/Out Bits (64-bit, 95th)
