Width/size of values?

What width data type are LocalLBPool statistics stored in? I'm getting this from test code:

 

 

| STATISTIC_SERVER_SIDE_BYTES_IN : 1922215810

 

| STATISTIC_SERVER_SIDE_BYTES_OUT : -1151353991

 

| STATISTIC_SERVER_SIDE_PACKETS_IN : 1374173472

 

| STATISTIC_SERVER_SIDE_PACKETS_OUT : -1836436750

 

 

This seems likely to be an overflow error, but I wanted to confirm.

 

 

TIA,

 

James

    icontrol returns 32-bit high and low numbers, which you'll need to convert to a 64-bit number.

    Powershell courtesy of Joe: 

     
 function Convert-To64Bit(){ 
   param($high, $low); 
  
   $low = [Convert]::ToString($low,2).PadLeft(32,'0') 
  
   if($low.length -eq "64")    { 
       $low = $low.substring(32,32) 
   } 
   return [Convert]::ToUint64([Convert]::ToString($high,2).PadLeft(32,'0')+$low,2); 
 }

    In python, you can see in this function to get wide IP statistics the same math: 

     
 def get_wideip_stats(obj): 
      
         try: 
                 stats = obj.get_all_statistics()['return'] 
      
         except: 
                 "Unable to fetch wideip list or get statistics - check trace log" 
      
         for x in stats['statistics']: 
                 print "WideIP: ", x['wide_ip'] 
                 print "\n"*2 
                 for y in x['statistics']: 
                     value = y.get('value') 
                     high = value.get('high') 
                     low = value.get('low') 
                     value64 = (high<<32)|low 
                     print "\t", y.get('type') , value64

    Does anyone have sample code for the Java version of this? Java's lack of unsigned long is making me grumpy.

    Search the forums for java 64-bit if this doesn't help you, as there at least a few examples

     

     

    long myresult_low = (long)(commonstat[5].getValue().getLow());

     

    long myresult_high= (long)(commonstat[5].getValue().getHigh());

     

    long myresult = (long)(commonstat[5].getValue().getHigh()<<32)+(long)(myresult_low);

    It is a 64 bit unsigned number: http://devcentral.f5.com/wiki/default.aspx/iControl/Common__ULong64.html

     

     

    Here's an article Don wrote on using the method in Java:
