[Hyperic-hq-discuss] getNetInterfaceStat(ifName).getSpeed() returns -1 on Linux (Red Hat 5.4)

[Jean <sig...@hy...>]

Hello,

I am using the interface speed to compute the % utilization of a network interface, but it does not seem to work on Linux.

This is the code that returns -1

ifstat = sigar.getNetInterfaceStat(ifName);
speed = ifstat.getSpeed();

This seems to work on Windows 32/64, Solaris, but not on Linux.

I was wondering if this is a limitation of the OS, or the SIGAR API.


In the documentation, it shows
Supported Platforms: Undocumented. 

but list 
System equivalent commands:
•AIX: 
•Darwin: 
•FreeBSD: 
•HPUX: /usr/sbin/lanadmin -g mibstats 0, netstat -i
[b]•Linux: ifconfig[/b]
•Solaris: 
•Win32: 



Thanks,
Jean
