How Can I See How Saturated My Interfaces/Bonds Are in Real Time?

Question

How can I see in real time how saturated my interfaces/bonds are?

Answer

To check how saturated interfaces/bonds are:

Use one of the following and change ***INTERFACE_NAME*** to your NIC/interface name which you want to check.

Paste it into your terminal on a server and it will show the current traffic throughput close to real time:

IFACE=***INTERFACE_NAME***; while true ; do raw0=`cat /proc/net/dev|grep $IFACE|awk -F':' '{print $2}'`;sleep 1; raw1=`cat /proc/net/dev|grep $IFACE|awk -F':' '{print $2}'`; r0=`echo $raw0|awk '{print $1}'` ; t0=`echo $raw0|awk '{print $9}'`; r1=`echo $raw1|awk '{print $1}'` ; t1=`echo $raw1|awk '{print $9}'`; echo -n "RX: $(( $(( $r1 - $r0 )) / 1048576 )) MB/s" ; echo -e "\t TX: $(( $(( $t1 - $t0 )) / 1048576 )) MB/s" ; done

CODE

Here are some examples for common interface names:

Eth0:

IFACE=eth0; while true ; do raw0=`cat /proc/net/dev|grep $IFACE|awk -F':' '{print $2}'`;sleep 1; raw1=`cat /proc/net/dev|grep $IFACE|awk -F':' '{print $2}'`; r0=`echo $raw0|awk '{print $1}'` ; t0=`echo $raw0|awk '{print $9}'`; r1=`echo $raw1|awk '{print $1}'` ; t1=`echo $raw1|awk '{print $9}'`; echo -n "RX: $(( $(( $r1 - $r0 )) / 1048576 )) MB/s" ; echo -e "\t TX: $(( $(( $t1 - $t0 )) / 1048576 )) MB/s" ; done

Eth1:

IFACE=eth1; while true ; do raw0=`cat /proc/net/dev|grep $IFACE|awk -F':' '{print $2}'`;sleep 1; raw1=`cat /proc/net/dev|grep $IFACE|awk -F':' '{print $2}'`; r0=`echo $raw0|awk '{print $1}'` ; t0=`echo $raw0|awk '{print $9}'`; r1=`echo $raw1|awk '{print $1}'` ; t1=`echo $raw1|awk '{print $9}'`; echo -n "RX: $(( $(( $r1 - $r0 )) / 1048576 )) MB/s" ; echo -e "\t TX: $(( $(( $t1 - $t0 )) / 1048576 )) MB/s" ; done
