    "Plug-in could not fetch fresh hardware data from the system" in EM12c

    1004789
      Hi,

      we've got two identical Servers (Sparc T4-1) with identical software (Solaris 10). I installed the agent on both machines without problems. Then I deployed the "Oracle Hardware Plugin".

      On Host1:
      Directly after deploying the status was "metric collection error". This error occured before on other Hardware Systems and our workaround ist creating a second target on the same host. Then both targets are up and the second target can be deleted. I reckon this has something to do with the delegation propagation. After deleting the dummy-target, everything is fine with the monitoring of host 1 and its hardware.

      On Host2:
      Same problem after deploying the plugin, so I created the dummy-target and the first target was marked as "up". But it doesn't collect anything. The error message in the EM12c reads "Summary     Plug-in could not fetch fresh hardware data from the system", the gcagent.log says:

      2013-04-23 08:17:02,958 [6251:B3B3446E:GC.Executor.1381 (host:<hostname>:LoadSunOS) (host:<hostname>:LoadSunOS:Load)] WARN - Found a row with more columns than declared for the metric for TargetID = <hostname>, Metric = Load
      Row = *** row contents suppressed ***

      I tried to undeploy and redeploy the plugin, but without success. Any suggestions?

          I looked in the logfiles on Host 1 and the same Warning occured, so that seems not the problem...

          when I'm trying to see the metrics via "Monitoring -> All metrics", the logfile shows:

          2013-04-23 11:22:41,375 [6111:3A50437] INFO - observed collection value for column "InletAirTemperature" is null for metric Meters on oracle_hardware target <target name>; removing
          2013-04-23 11:22:41,375 [6111:3A50437] INFO - observed collection value for column "ExhaustAirTemperature" is null for metric Meters on oracle_hardware target <target name>; removing
          2013-04-23 11:22:41,375 [6111:3A50437] INFO - observed collection value for column "ActualPowerConsumption" is null for metric Meters on oracle_hardware target <target name>; removing

          which the Host1 with working plugin does not.
