如何在Java中监视特定接口的网络使用情况？

Question

我想知道通过特定网络接口传输的确切数据量用于记录目的，是否有任何标准库或api调用，我可以通过这种方式以交叉平台方式执行此操作？

Answer 1

This seems to do what you'd like. At least, I think it will point you in the right direction: http://jnetpcap.com/

edit: While not strictly cross-platform, libpcap has libraries for all major platforms so I wouldn't consider that a show-stopper, but I'm not the one that needs it.

Answer 2

jNetPcap uses Sigar in some of its unit tests. Sigar advertizes itself as a "portable interface for gathering system information" including network interface detection, configuration info and metrics. Take a look at its NetInterfaceStat class.

Note that Sigar also relies on platform specific JNIs, ie Rob H's remark still applies.

Answer 3

SNMP4J will let you read the interface mib of any SNMP-compliant device. Linux and OSX (probably) have an SNMP daemon already running; Windows has an SNMP service that you can install though Programs and Features in Control Panel .
