27 |
|
|
* -d <number> Takes the number of seconds to wait to get traffic sent since last call |
28 |
tdb |
1.5 |
* Note, this is not network traffic per second. Its the traffic since last |
29 |

|
* call. If you want it traffic per second averaged over time since last call |
30 |
pajs |
1.1 |
* You need to divide against the time since last time this was called. The time |
31 |
