No CPU and Mem showing for AIX boxes under node details

I have several AIX boxes and while I can look at the CPU and Mem load in the System Manager client or by hovering over the node but if I go into node details I do not see it.  Works just fine for any of the other hundreds of nodes I have just AIX appears to have this behaviour.

There are no filters or account limitations inplay.

  • HI Donald, Did you ever get an answer for this issue?....

  • The answer was that out of the box NPM does not monitor those MIBs.  It can be done with a custom poller however.

  • It may be a little deeper than that.. IBM's AIX doesn't fully support SNMP.  Specifcally the IBM AIX SNMP that is compiled by default doesn't compile the HOST-RESOURSE.MIB this is where you get process info, better cpu, memory, and better disk.  You have to compile NET-SNMP or use custom scripts to monitor your AIX environment.

  • Here is what I found out and did to resolve this issue.

    With the OS upgrade, IBM switched to SNMPv3 as the default. You need to switch back to SNMPv1. The following is how this is done.

    Modify SNMPD.CONF file
    vi /etc/snmpd.conf

    logging         file=/usr/tmp/snmpd.log         enabled
    logging         size=0                          level=0

    ps -ef |grep mib

    Switch from SNMPv3 to SNMPv1. This will auto link necassary files
    ls -l /usr/sbin/snmp*
    /usr/sbin/snmpv3_ssw -1

    Created file
    vi ChangeSNMP
    ./ChangeSNMP

    #! /bin/bsh
    chssys -s hostmibd -a "-c <Community String>"
    chssys -s aixmibd -a "-c <Community String>"
    stopsrc -s snmpd
    stopsrc -s aixmibd
    stopsrc -s dpid2
    stopsrc -s hostmibd
    startsrc -s snmpd
    startsrc -s dpid2
    startsrc -s hostmibd
    startsrc -s aixmibd
    exit

    chmod 755 Change*
    ./ChangeSNMP

    Validate switch to SNMPv1

    Change bind to bind4 (This forces it to use IPv4 instead of IPv6 first)

  • Hi Holewink​!

    We were having issues with AIX 7.1. We configured SNMPv3 on the server using IBM 7.1 guide. The node is responding to snmp but when doing "list resources", we can't see any CPU/MEMORY/DISK/VOLUMS etc as well.. only ping via ICMD or SNMP.

    Can you help us with this?

    Br,

    Ian

  • I have not implemented SNMPv3 only SNMPv2. I do have one AIX system that exhibits the same results and I have not been able to resolve this. The configuration files appear to be the same when compared to other systems that are working. Sorry I cannot help.
