• 環(huán)境說明
  操作系統(tǒng):Centos7
  安裝zabbix-release
  node1:10.193.116.98 安裝zabbix-server模塊
  node2:10.193.116.97 安裝zabbix數(shù)據(jù)庫模塊
  node3:10.193.116.96 安裝zabbix-web模塊
  node4:10.193.116.95 安裝zabbix-proxy模塊

        allow 127.0.0.1/8;
        deny all;
}

• 編寫監(jiān)控腳本

  Nginx每秒請(qǐng)求超過100

• 壓測(cè)觸發(fā)告警

安裝ab壓測(cè)工具
