NAME

sbm — simple bandwidth monitor

SYNOPSIS

sbm [-B | -t] [-c count] [-d delay] [-i interface]

DESCRIPTION

sbm is a simple bandwidth monitor.

OPTIONS

-B: Show values in bytes instead of bits in default output.
-c count: Stop monitoring after count samples. If count is 0, it will loop forever. This is the default.
-d delay: Sample interface statistics every delay ms. The default delay is 1000 ms.
-i interface: Monitor the selected interface. If not provided the first active, non-loopback interface will be used.
-t: Enable terse output. The first pair of values is Rx/Tx in bits per second and the second pair is Rx/Tx in packets per second.

SIGNALS

If sbm receives a SIGINFO (usually set to ‘^T’) signal (or SIGUSR1 on Linux), the accumulated amount of data transmitted for Rx and Tx and the time since the program started will be printed to the standard output.
