SNMPD 处于活动状态，但出现状态错误

Question

我有一个运行在 Debian 8 上的服务器，上面运行着 snmp 服务。 但是，当我得到 snmpd 的状态时，它说它正在运行但出现错误：

service snmpd status:

snmpd[30734]: Cannot statfs /sys/kernel/security
              : Permission denied
snmpd[30734]: Cannot statfs /sys/kernel/config
              : Permission denied

我需要它来用 Zabbix 监督这个服务器

更新：

/etc/default/snmpd 中的 SNMPDOTS：

SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid -c /etc/snmp/snmpd.conf'

更新： 这是我收到的错误消息（完整）：

您好，您需要以管理员身份执行此命令；）：

sudo -i  //login as admin if the user are in group of sudo
service snmpd status   //no problem 

#backup the file before

SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -g snmp -I -smux,mteTrigger,mteTriggerConf -p /run/snmpd.pid'
