Allowed operation between jmx attribute and reference value:
  • == equals
  • != not equals
  • > greater than (&gt;)
  • >= greater than or equals (&gt;=)
  • < lesser than (&lt;)
  • <= lesser than or equals (&lt;=)
NOTE: For numeric expressions the type must be set and use xml entities as operations.
As type we currently support long and double.
