UNIX for Dummies Questions & Answers

Hi i m running a command

Code:

watch -n 1 -d netstat -i

to see the packet drops every 1 second.
but the problem is the output is so long(Due to large number of virtual interfaces) it doesn't fit into the putty prompt.

I dont need to monitor each and every network interface I m more interested in monitoring the interfaces starting from vif but whenever i run following command it doesnt display anything.

Code:

watch -n 3 -d netstat -i | grep vif*

What should i do?

hi can u post sample o/p of the command

Code:

watch -n 1 -d netstat -i

This being production machine i can't post the output .But its used as Server Hosting the virtual guests using xen technology.
There for the number of network interfaces are more.

does this work for u

Code:

watch -n 3 -d netstat -i | grep vif

Try this:

Code:

watch -n 1 -d "netstat -i |grep vif"

Its working now.
