    Hi,

    why do you use OS agent and even NMON data thorugh lpar2rrd os agent?
    It just doubles same data.

    send us
    ps -ef| grep lpar2rrd
    ls -ltr /var/tmp/lpar2rrd*
    ls -l /var/nmon | wc -l

    Hi, Pavel.

    Why? Because can do it. You say it may do:
    (https://www.ibm.com/developerworks/community/forums/html/topic?id=4b21495b-cf50-47c0-9144-da7b32b8f8f5)

    yes, you can use only NMON  (NMON is independent on the OS agent, both just use the same script/program).

    In fact you have 3 independent options:

    1. NMON only

      /usr/bin/perl /opt/lpar2rrd-agent/lpar2rrd-agent.pl -n __NMON_DIR__  __LPAR2RRD-SERVER__

    2. OS agent only

      /usr/bin/perl /opt/lpar2rrd-agent/lpar2rrd-agent.pl __LPAR2RRD-SERVER__

    3. both

      /usr/bin/perl /opt/lpar2rrd-agent/lpar2rrd-agent.pl -n __NMON_DIR__  __LPAR2RRD-SERVER__

      /usr/bin/perl /opt/lpar2rrd-agent/lpar2rrd-agent.pl __LPAR2RRD-SERVER__

    Cheers, Pavel

    :-)

    E-mail on the way.

    Pavel, i edited  near string 337, and replase from old script who works with nmon 

    #A#    my @ps        = grep {/$0(?!grep|sh -c)/} `ps -ef 2>>$error_log`;
        my @ps        = `ps -ef 2>>$error_log|grep $0|grep -v grep|grep -v "sh -c"`;
