Pinned topic nmon2rrd - CPU vs Entitlement is empty on Power7 Systems

‏2010-12-15T14:24:24Z |
Hello Guys,

the graph "CPU vs Entitlement" is on Power7 systems empty :S

on the Power7 Systems with AIX 6.1 the graph is empty (see attachement)
  1. AIX: 6.1.6.2
  2. Hardware: Architecture PowerPC Implementation POWER7 64 bit

on the Power5 System I have no problems with this graph
  1. AIX: 6.1.4.4
  2. Hardware: Architecture PowerPC Implementation POWER5.2 64 bit

does anyone have the same problem or maybe a solution?

regards,

strawberryhero

    Data file please

    Hi,
    This is pretty hard to debug.
    Can you append a small data file that shows the problem?

    Then I can at least reproduce it and check the data file content.

    Thanks, Nigel Griffiths

      Hi Nigel,

      I have attached a complete Nmon_log from Saturday (I have just modified the server name and some filesystems).

      regards,

      Matthias

      Hi Nigel,

      I have encountered the same problem for a while. Unlike others, I have the same problem with nmon data from data captured on Power5 machines, be it AIX 5.3 or 6.1. I think the fix is actually rather simple. The root cause has more to do with how nmon2rrd version 12g determines the version of nmon in use. The nmon2rrd code was designed to parse the LPAR data if the nmon data was collected using either version 12e, 11e, 11d or legacy. Data from nmon utility newer than 12e would fail. Or the problem may also occur if using an older version of nmon2rrd (like version 12f) on nmon data generated by with nmon version 12e or newer.

      This is all based on the fact that the latest nmon2rrd download (version 12g) at http://www.ibm.com/developerworks/wikis/display/WikiPtype/nmon included the source code, which I was able to investigate. Of course, I can't know for sure since I do not have a compiler, due to the nature of the industry I work at. Nigel, will you please take a look and verify, and release a newer version of the nmon2rrd binary if everything checks out?

      Thank you very much.

      PS: Now that nmon versioning is generic, should you include additional columns of data capture in the LPAR section, this fix will break again, because of the logic used herein that determines how many columns are used is not able to distinguish the AAA,version field.

    Hi All, Even I face the same problem on power7(p770) hardware and not on power5 (p595)
    1. Cannot see "LPAR" tab generated
    2. Hardware model in "AAA" reflects as "Architecture PowerPC Implementation unknown 64 bit"
    Hardware : IBM,9117-MMB POWER7 P770
    OSLEVEL : 5300-12-04-1119
    Nmon version : v11e
    Analyzer version : v33g

    Hi,
    It depends on what nmon you are using for collecting the data. Nmon2rrd needs to know
    all the columns of data, otherwise it would fail.

    On AIX 6 and 7 you should use topas_nmon to collect data. There is a nmon2rrd version
    I edited, that should work on the most of cases. At least it should work with all the current
    aix 7 + topas_nmon setups. See my other thread on that matter ( search for "vworking" :P ).

    AIX 6.1.4.4 + topas_nmon will, most likely fail since I do not have one to work with...
