      Description

      I suggest two fixes for JMX Generic template relating to two issues:

      1.ProcessCPULoad issue

      jmx["java.lang:type=OperatingSystem",ProcessCpuLoad].last(0)>0.7
      

      ProcessCpuLoad of JMX is a value between 0 and 1. But in this JMX template it is multiplied by 100 and have units of %. It trigger is however trying to fire
      for all values higher than 0.7 which is 0.7 % and not 70%.
      Again it is giving alarms where shouldn't be any as ProcessCPULoad is only 0.7% and not 70%.

      fixing by changing trigger to:

      jmx["java.lang:type=OperatingSystem",ProcessCpuLoad].last(0)>70
      

      2.Timeout issue

      jmx["java.lang:type=Runtime",Uptime].nodata(1m)=1
      

      is too unforgivable to the system as nodata with 1m and polling interval of once a 60 seconds. This combo gives too many false positives and event that last only few seconds but happen almost every time.


      I suggest changing it to

      jmx["java.lang:type=Runtime",Uptime].nodata(3m)=1
      

      Diff patches for xml of template (version 2.4.7) are attached.

       poll once a minute :) )
