    Exporting JMX to SNMP using snmp-adaptor.sar

      I am exporting float values as jmx atttributes using spring 3.0 in the following way:

       

      @ManagedResource(objectName = "foobar:name=XYZVerarbeitung", description = "Kenndaten der XYZ Verarbeitung", 
  currencyTimeLimit = 15, persistPolicy = "OnUpdate", persistPeriod = 200, 
  persistLocation = "Loader", persistName = "XYZBAR")
public class QueueNachrichtMdp implements MessageListener {
....
....
    @ManagedAttribute(description = "Anzahl der verarbeiteten Datensaetze", currencyTimeLimit = 5)
    public long getMessageCount() {
        return anzahlBearbeiteterMessages;
    }
    @ManagedAttribute(description = "Durchschnittliche Laufzeit einer Datensatzverarbeitung", 
      currencyTimeLimit = 5)
    public float getDatensatzLaufzeit() {
        if (anzahlBearbeiteterMessages == 0) {
            return 0;
        } else {
            return summeMessageLaufzeiten / anzahlBearbeiteterMessages / 1000f;
        }
    }

       

      The methods are exported like that:

       

      <mbean name="foobar:name=XYZVerarbeitung
" oid-prefix=".1.3.6.1.4.1.4952.100.200.1.2.2">
     <attribute name="DatensatzLaufzeit" oid=".1"/>
     ....
     <attribute name="MessageCount" oid=".4"/>
     ....
   </mbean>

       

      Collecting "MessageCount" works properly - if i try to collect "DatensatzLaufzeit" (1.3.6.1.4.1.4952.100.200.1.2.2.1) i get the follwing logmessage:

       

      18:34:54,609 INFO  [ServerImpl] JBoss (Microcontainer) [5.1.0.GA (build: SVNTag=JBoss_5_1_0_GA date=200905221634)] Started in 1m:18s:393ms

      It seems that exporting float values is currently not possible snmp-adaptor.sar - is this correct?
