monitoring traffic on loopback interface

Antonio Cardoso_1 — Mon, 23 May 2005 05:15:11 GMT

Hi,

is there some command on a HP-UX 11i server to obtain statistics about internal IP traffic (on loopback interface), such as we get with
lanadmin -g mibstat 0
on lan0 interface

thanks.

You can get a basic in/out/error packets count with: -

netstat -I lo0

hi,

If you have glanceplus installed then you can have online updates of the trafic on the lan interfaces.

# glance -l

Hope that helps.
Regards,

I'm also interested in monitoring usage of system resources linked to network usage: I/O buffers or other counters associated to network interfaces.
Is glance the answer?
If so I'll consider evaluation the trial version.

Is there a relevant document to get some knowledge on that topics?

thanks.

Apart from the packet and/or byte counts, none of the other statisics you see from lanadmin -g mibstats really applies to lo0. There is no queue per se, no chance for collisions, or FCS errors or whatnot. Glance and Measureware (or whatever we call it these days :) are indeed good tools, and could be useful here, but netstat will show you pretty much all there is to know about loopback. Measureware though will keep a history you can consult for trends and whatnot.
