  • Hi Pavel,
    installed IBM i Agent on a IBM i partition. (after upgrading LPAR2RRD)

    about installation:
    1: Changing command Defaults,
    in documentation: CHGCMDDFT CMD(LPAR2RRD/RTV_SYSSTS) NEWDFT('IPADR("192,168,2,1")'), this doesnot work, CHGCMDDFT CMD(LPAR2RRD/RTV_SYSSTS) NEWDFT('IPADR''192,168,2,1'')') does work.
    one double quote versus two single quotes

    2: Authorization:
    The IBM i Agent use API "dlpar_get_info" in service program QPMLPMGT
    default authorization on this Service Program is *PUBLIC *EXCLUDE
    IMHO User LPAR2RRD should not be given any special Authorization.
    To give USER LPAR2RRD authorization to use the API: GRTOBJAUT OBJ(QPMLPMGT) OBJTYPE(*SRVPGM) USER(LPAR2RRD) AUT(*USE)

    About Metrics:
    1: I would like to see "Current unprotected storage used / Maximum unprotected storage used." in one graph, this is temporary storage used.

    2: ADDR IMHO these metrics are not really interesting to monitor so frequently.
    According to http://www-01.ibm.com/support/docview.wss?uid=nas8N1019798 : "A primary cause of temporary address consumption is a high volume of native database file opens." I made a test program on a Power6 machine (0.5 processor) IBM i 7.1. This test program loops doing native database file opens and close only. In one week temporary address was at 0.8 % . I cannot remember seeing a system with temporary addresses above 10%.
    according to http://www-01.ibm.com/support/docview.wss?uid=nas8N1015972 : "Many systems typically have a low percentage of temporary addresses used."

    3: POOLInfo: IMHO Reserved size is not interesting, I'm working quite some years with IBM i and its predecessors, and never had to to something with "Reserved size"


    Next
    going to install the agent on more partitions.


    Thanks
    Ad.






  • Hi,

    thanks for feedback.
    1. we have already fixed that double quotes issue in the documentation earlier today.
    2. exactly, also this one has appeared in the docu already earlier today

    Metrics
    1. we will check it out, it should be possible
    2. we have already got similar feedback while ago, it will be removed if that metric is not interesting. we have just kept it here for now when it is already developed
    3. same as above, it is also a candidate for ignoring :)

    Keep posting ideas :)

    Thanks!
  • Hi,
    Love the product. Have been using LPAR2RRD for a long time to keep an eye on current and historical CPU utilisation by our IBM POWER servers, individual LPARs, aggregate LPARs etc. And then it gets even better with the new IBM i (AS/400) agent.

    Can anyone advise please on the following error when I start the agent jobs on an IBM i LPAR? The first message is as expected, but then we see the error

    IF: C_SNDSTS - protocol 5.0 UTF8 conv
    Er: C_SNDSTS - connect() errno = 3447

    The LPAR2RRD server runs on an AIX system where the LPAR2RRD deamon has been started, listening on port 8162. I suspect we may have some firewall rule preventing the connection.

    Thanks
    JT

    Hi,

    yes, it is a connection problem.
    1. Check troubleshooting section on the botom of http://www.lpar2rrd.com/as400-install.htm

    2. Try to connect LPAR2RRD server from another Unix machine in the same network subnet:
    telnet 8162

    3. look at the LPAR2RRD server log if anything related
    cd /home/lpar2rrd/lpar2rrd
    vi logs/error.log-daemon

    Cheers,
    Pavel
  • Hi Pavel,
    Sure enough there is a firewall rule that required updating to allow the IBM i agent to connect to the LPAR2RRD server. Works great now.

    Thanks,
