AIX OS Agent incorrect network stats

Hi,

I am running lpar2rrd-agent-6.10-0 on an AIX 6.1 server, and noticed, that the network stats are incorrect.
We have 5 networks as en3,en4,en5,en6,en7. 
By far the busiest network is en7, yet in the graphs, all of the networks report exactly the same utilisation.

Here is a text extract of the graph.

    Hi,

    I cannot see pictures, but send us this from the agent side:
    ls -ltr /var/tmp/lpar2rrd*
    tail /var/tmp/lpar2rrd*err
    cat /var/tmp/lpar2rrd-agent1.out

    Just to report the same issue. Details: The interfaces are VLAN, and each showing same traffic, which is actually total for the whole trunk port (LACP Link Aggregation).

    Hi,

    just interfaces with IP assigned whould be presented. Has you vlan interfaces assigned an a IP?

    do you seen any difference in entstat output?

    entstat -d <interface>| grep "Bytes"
    sleep 60
    entstat -d <interface>| grep "Bytes"

    same for the other interface on the other command line session

    Is delta values more less same for each interface

    Hello,

    Sorry , lost focus back in time,

    To answer the questions:

    - Yes, all vlan interfaces have IPs assigned,

    - entstat - scripted (bash) in one session (I use single terminal):

    #for i in {18..22}; do echo -n "en$i :" ;entstat -d en$i |grep "Bytes"; done; echo; sleep 60; for i in {18..22}; do echo -n "en$i :" ;entstat -d en$i |grep "Bytes"; done

    Deltas are similar

    Hi,

    yep, data is similar, we present just what we get from entstat, it is correct on our side as you can see it.

    We have already got a fdew other users with the same issue.
    It is always same, entstat reporting nearly same data throughput.
    I do not know how it is possible, it is more question for AIX support.

    ok...
  • Pavel
    Pavel
    let us know result if you raise a support case with IBM

    As a workaround i started using nmon as an additional source.
