NIC throughput

Julio Porras_1 — Thu, 01 Jul 2004 14:28:33 GMT

I have an rp5470 with several NICs (1 ATM, 1 FDDI, 1 GBIT, 1 Fast ethernet) and I would like to monitor bandwidth or traffic sent throu each of these NICs. Is there a tool in HP-UX for this? like a bandwidth meter?

Hi Julio,

"Measureware" can get you that information. It's a licensed product so you will have to purchase it.

Once it is installed, up and running, it will collect the metrics of all the network interfaces and you can get the historical data (BYNETIF metrics) anytime using the command 'extract' and import it into excel. If you have perfview, you can view the data graphically.

Measureware is a nice to have tool. There are other products also in the market but this is found to be widely used on HP systems.

Use the following script.

#Script for chekcing lan i/p and o/p stats.

let z=0

let y=$(lanadmin -g mibstats 0|grep -i oct|grep Inbound|awk '{print $4}')

let y2=$(lanadmin -g mibstats 0|grep -i oct|grep Outbound|awk '{print $4}')

while true

do

let x=0

sleep 1

x=$(lanadmin -g mibstats 0|grep -i oct|grep Inbound|awk '{print $4}')

x2=$(lanadmin -g mibstats 0|grep -i oct|grep Outbound|awk '{print $4}')

let t=$x-$y

let t2=$x2-$y2

let y=$x

let y2=$x2

let z=$z+1

let t=$t/1000

let t2=$t2/1000

echo "${t} Kb/s inbound, ${t2} Kb/s outbound"

done

Hi,
Glance is the best option if you have it.. it is a priced product.
If you don't have one then you can use "lanadmin" to see the traffic (packet level) on each NIC.

Great script RAC, you got 9 points for it. It worked great for my ethernet and FDDI NICs. Unfortunately, it does not work for my ATM NIC, since it wont show up on lanadmin. Why is that so?

Thank you all for your responses. Any other feedback appreciated.

You may also look at by_net metrics og glance. This will give you same thing that script gives. And you will have lot of options there.

you look at examples in /var/opt/prf/adviser/examples.

An ATM NIC is not a "LAN" NIC so it doesn't work with landiag. There is/was (IIRC) a similar utility for ATM - the ATM docs on docs.hp.com would be the place to go.

If you don't want to go the glance/Measureware route, if you have SNMP enabled, you could get OpenView to monitor the octet counters in the interface MIBs, or you could try to use mrtg.
