Multiple client data errors "not a simple unsigned integer"

Hi,

We are seeing many clients (AIX), not transferring. LPAR2RRD v5.7 rrdtool 1.7.0.3
eg
Fri Jan  4 14:16:38 2019: Client communication failed - client:  (xxx.xxx.xxx.xxx): ERROR: /opt/lpar2rrd/lpar2rrd/data/<server>/<HMC>/<VIO>/san-sissas0.mmm: not a simple unsigned integer: '0.0' at /opt/lpar2rrd/lpar2rrd/bin/lpar2rrd-daemon.pl line 1067.  :

Not always the same stat, also san-vscsi0.mmm, across several clients (mainly VIO servers), yet the other VIO is fine.

Am I missing an option. We have 2 instances one is fine, the other suffers this problem.

Thanks

    Example of data that fails from client

    8286-42A*782C51X:<host>:15:1543785540:Sun Dec  2 21:19:00 2018 version 5.05-8:3525000000|4:<host>:0::mem:::50331648:42848432:7483216:5685804:0:988556:pgs:::3104134:4322169:20992:4:::lan:en0:10.16.202.176:9111917618195:1202109899571:2667507758:2864238838:::ame:::13199:420:0::::cpu:::0:6:28:1:::san:vscsi0::9931336.5:818200:510.6:89.4:::san_resp:vscsi0::0.7:0.3::::

    The 89.4 filed is the one in all occasions. Seems lpar2rrd thinks this has to be an integer

    You have upgraded the agent on the higher release than was (is) lpar2rrd server which does not support some SAN/SAS data.

    What is LPAR2RRD server version?

    Thanks for the reply

    head lpar2rrd.cfg
    #
    # LPAR2RRD main configuration file
    # LPAR2RRD home : http://www.lpar2rrd.com
    #
    version=5.07

    (client) rpm -qa
    lpar2rrd-agent-5.05-8.ppc

    ok, rrdtool file could be created already by older server version not compatible with newer agent.
    Remove that file, it will be re-created, then all hist data since 2nd Dec will be loaded..
    /opt/lpar2rrd/lpar2rrd/data/<server>/<HMC>/<VIO>/san-sissas0.mmm

    remove even other adapters san-sissas1,2,3... for that vios server like in this example:
    rm /opt/lpar2rrd/lpar2rrd/data/<server>/<HMC>/<VIO>/san-sissas*.mmm

    Hi Pavel,

    Thanks for this, it seems to have worked.

    So my next question is : is it possible to merge 2 LPAR2RRD instances into one ? Now both our instances are on 5.07, is there a procedure to easily move and combine instances ? The idea would be to have a new server host the new website, maybe on the new version (still in beta ?) of LPAR2RRD ?

    Thanks

    Hi,

    yes.
    1. attach all HMCs on the target instance
    2. copy over data directory (use tar, not cp due to used hardlinks)
    3. ./load.sh

    Ctrl-F5 in the UI

    Make backup at first :)
