centos - Linux (Centos) 上的 SNMP 未显示平均负载

Question

我在我的 Linux 上安装了 SNMP 以监控负载平衡、磁盘空间等。

yum install net-snmp net-snmp-utils
vim /etc/snmp/snmpd.conf   # added "rocommunity  public"
/etc/init.d/snmpd start

走 SNMP 返回很少的条目，没有平均负载，磁盘空间等:

发现问题:

需要完全重置 .conf 文件:

echo "rocommunity public">/etc/snmp/snmp.conf

需要指定要行走的确切分支:

snmpwalk -v 1 -c 公共(public)本地主机 .1.3.6.1.4.1.2021.10
