Snmp 如何将量规32转换为整数？

有人能帮我吗？我正在尝试监测网络设备的湿度，我进行了snmpwalk，即： snmpget-v2c-cpublic-mALL 172.x.x.x.x.1.3.6.1.4.1.13742.4.2.x.x.x.x.x 它说： SNMPv2 SMI:：enterprises.13742.4.2.4.1.x.x=Gauge32:2147483647

那么，量规32意味着什么？有什么方法可以将其转换为整数吗？

您尝试轮询的MIB对象在PDU-MIB中定义，来自raritan[]

因此，您的相对湿度应在[0..100]范围内。可能存在两个问题：

由于某些原因，NET-SNMP无法正确显示该值

SNMP代理未实现此对象，或者设备上未安装或禁用湿度传感器

Gauge32在内部是一个无符号32位整数。你面临的问题是什么？转换成整数几乎是自动的。谢谢您的回复。我编辑了我的问题，可能是重复的
