Question

我正在尝试使用SNMP获取服务器的正常运行时间。首先，我检查服务器是否在线，然后我尝试检索正常运行时间。问题是我想多次运行该命令以减少脚本中的延迟，但我没有将预期的输出输入到数组中。

for ip in "${Iparray[@]}"
do
    uparray=($(snmpwalk -Os -c public -v 1 $ip DISMAN-EVENT-MIB::sysUpTimeInstance | grep "^sysUpTimeInstance" | awk '{print $5}')) &
done
tail /proc/uptime | grep -o '^\S*'
wait $(jobs -p)
for ti in "${uparray[@]}"
do
    echo $ti
done

在脚本之外运行命令时得到的输出是：

5:58:27.35

但在剧本里面我得到了：

Timeout: No Response from 192.168.0.2
Timeout: No Response from 192.168.0.3

任何帮助都会很棒。可能是我看过的脚本中的一个小问题。
