Netzwerkkarten statistik unter windows gesucht

[Mad-Marty]

Hallo,

hat jemand schonmal versucht unter windows ähnlich zu linux, die bytes received, sent, error usw zu bekommen?

Ich habe es über die WMI und "Win32_PerfFormattedData_Tcpip_NetworkInterface" versucht, nur leider sind die meisten counter auf 0, was wohl am treiber liegt.

"net statistics workstation" zeigt zwar etwas an, aber leider nicht mehr komplett und auf die IFs zugeordnet.


Hat wer einen guten Tip um an die Performance Daten zu kommen?

Bin jetzt über ctypes und IPHLPAPI.DLL gegangen ... aber nun crasht python
