安裝 Apache Agent 的方式
- 這是 SNMP Extend
- Apache 要啟動 mod_status 模組
vi /etc/httpd/conf.d/server-status.conf
內容大概類似以下
<Location "/server-status"> SetHandler server-status Order deny,allow Deny from all Allow from localhost Allow from 192.168.1.132 </Location> - 重新載入設定檔進行驗證
systemctl reload httpd curl http://localhost/server-status
如果沒問題顯示結果類似以下<xtermrtf>
