使用 Nagios 來偵測無線 AP 時會出現 No OIDs specified 的警告訊息
[@more@]解決方式：
1. 修改 commands.cfg
# vim /etc/nagios/object/commands.cfg
或
# vim /usr/local/nagios/etc/objects/commands.cfg
把
# ‘check_snmp’ command definition
define command{
command_name check_snmp
command_line $USER1$/check_snmp -H $HOSTADDRESS$ $ARG1$
}
修改成
# ‘check_snmp’ command definition
define command{
command_name check_snmp
command_line $USER1$/check_snmp -H $HOSTADDRESS$ -C $ARG1$ -o $ARG2$
}
2. 重新啟動 Nagios Server
# systemctl restart nagios.service
check_snmp 指令用法
# /usr/local/nagios/libexec/check_snmp
