Australian TZ, recently changed to daylight savings, I probably should check all components are on the correct time.

lpar2rrd@tca-infrarrd:~/lpar2rrd/logs$


I've gone though the docs, all pre-req's exist, including the downgrade of liblwp-protocol-https-perl to 6.07-2
I'm sure its something trivial I've missed

If you have any tips, off the top of your head, which I should look for, that'd be appreciated :)

    Hi,

    1. is HMC test connection working?

    2. the agent side, run the agent with "-d" option to force send data immediatelly, any error?
    $ /usr/bin/perl /opt/lpar2rrd-agent/lpar2rrd-agent.pl -d <LPAR2RRD-SERVER>

    HMC connectiosn are working fine, I'm getting all the hypervisor stats, but its producing a lot of events in the log. The HMC is managing several full system Power7 IBM i LPARs as well as Power7s with VIOs plus Power8s with VIOs
    Regarding the daemon, yes, I can run the lpar2rrd-agent.pl -d on the VIO servers and it successfully transfers the data, but the daemon on the server is not populating lpar2rrd's files with the data its receiving.
    I'll take another look at it later today

    Just checked and its all looking good now, the data is showing up in the lpar2rrd interface now. I'll review the logs and see if those errors have gone away. Thanks for checking this out.
