Re: iSeries NIC Utilization

[Alexei Pytel <pytel@xxxxxxxxxx>]

Every NIC has its own communications line description.
MC monitors track utilization by line description.
You should be able to see traffic, errors etc. separately for each line 
description.

Collection Services also exports communication statistics by line 
description.
You may want to check QAPMETH performance database file (I assume you have 
Ethernet. Other protocols go to other files.)
In addition, QAPMTCPIFC file reports statistics per TCP/IP physical 
interface.

iSeries NIC Utilization






Our iSeries has 3 NICs. Using our external and internal DNS tables we
route all off campus traffic to one NIC, and all on campus traffic to a
second. The third is there as a backup in case either of the others fail
and we can switch over to this third NIC manually. All three are online,
included the spare.  I would like to be able to see how much traffic is
coming in on the two active NICs and also see which of the three NICs
traffic is going out on.  Management Central monitor can start a LAN
utilization monitor but it does not let me pick which NIC to watch so I
can only assume it's watching all traffic.  I think I could add an
external SNMP monitor to check that way but wanted to be able to check
internally to the iSeries and possible log use to a database.

 

Thanks
