Need Call Statistics report of RPC server

I am trying to log Debugger’s “call statistics” from a Natural batch RPC server. I used SYSRPC to set-up several subprograms for access from an on-line session. To keep things simple, I set NTASKS=1 in my RPC parameters. I initialize Debugger as the RPC server comes up via the STACK parameter. The JCL includes

//CMPRINT   DD SYSOUT=*               NATURAL LOG    
//CMPRT10   DD SYSOUT=*               SERVER LOG     
//CMHCOPY   DD SYSOUT=*               CALL STATISTICS
//TRACE1    DD SYSOUT=*               SERVER TRACE   
//CMPRMIN   DD *                                     
STACK=(LOGON library,user,pswd;RGZCSIN)
/*

RGZCSIN invokes Test Mode and starts Call Statistics.

STACK TOP COMMAND "TEST SET CALL ON"   /* CALL Statistics
STACK TOP COMMAND "TEST ON"            /* Test mode      
END                                                      

To print the statistics, I invoke subprogram RGZCSPR via RPC. RGZCSPR also includes a CALLNAT to USR600N.

DEFINE DATA LOCAL                         
1 #M (A8/32)  (HD='Module')               
1 #L (P3/32)  (HD='Lvl')                  
END-DEFINE                                
WRITE '=' *LIBRARY-ID '=' *PROGRAM 'print'
STACK TOP COMMAND "TEST PRINT CALL"       
CALLNAT "USR0600N" #M (*) #L (*)          
DISPLAY (ES=T ZP=F SG=F) #M (*) #L (*)    
STOP                                      
END

With this set-up, no RPCs are included in the Call Statistics report, nor are lower-level CALLNATs, nor are programs which are invoked within the subprograms via FETCH RETURN.

CMPRINT contains

1Call statistics started.

but CMHCOPY is empty. :cry:

When I change the STACK parameter to include one more program, say RGZCSPGM, that program, plus its CALLNATs are included in the report.

STACK=(LOGON library,user,pswd;RGZCSIN;RGZCSPGM)

It would appear that logging begins with level 1 modules in the RPC server. But, if I invoke any of the logged subprograms via RPC (eg RGZCSSB2), those RPC calls are included in the statistics.

Is this a bug? To me, it doesn’t indicate a C/E. In either case, my Technology Partner status does not authorize me to log this formally in Empower, and there are too many levels of bureaucracy to ask my client to ask their data center support to call SAG. Perhaps a Forum Moderator (Wolfgang Weil?) could assist.
