				Hello,
 
 
I have configured mqat.ini like:
 
 
 
   
	| Code: | 
   
  
	AllActivityTrace:
 
  ApplClass=USER
 
  ActivityInterval=1
 
  ActivityCount=100
 
  TraceLevel=MEDIUM
 
  TraceMessageData=10000
 
  StopOnGetTraceMsg=OFF
 
  SubscriptionDelivery=BATCHED | 
   
 
 
 
 
according to the information provided from the vendor:
 
 
TraceMessageData	0 - 104 857 600 ( maximum 100 MB)	Amount of message data traced in bytes for MQGET, MQPUT, MQPUT1, and Callback operations
 
 
In my case it is 10000 bytes. but even in this case - I have tested with some sample text with amqsput:
 
 
"Prevent the sample activity trace program from generating data"
 
 
and in the end I receive :
 
 
"Prevent the sample activity trace progra"
 
 
 
'messageData': '68652073797374656D207265736F7572636520524C494D49545F4E4F46494C452069732073657420', 'msgLength': 152,
 
 
I am reading with amqsevt .. -q SYSTEM.ADMIN.TRACE.ACTIVITY.QUEUE -w 1 -o json | jq . -c --slurp
 
 
 
Do you know why is this happening, am I missing something..
 
 
 
thank you ! _________________ Regards

				I have answered myself ..   
 
 
#define MAX_FORMAT_DATA_LEN (40)  /* Max bytes to print of message data */
 
 
 
So here is the other question .. if I change this to 10000, what will be the change to the CPU/MEM usage .. is there some optimal max limit that has no impact to the QM 
 
 
 
thanks _________________ Regards
