Simple Queue From Mikrotik is not working in cacti

Hi everyone

I m trying to configure Mikrotik simple queue on my cacti as per following tutorial :

http://forum.mikrotik.com/t/cacti-mikrotik-routeros-statistics-update-11-19-2013/18506/1

but i getting error the RRD files does not exist. but i m getting the ether graphs perfectly !

RRDTool Says:
ERROR: opening ‘/usr/share/cacti/rra/server_traffic_in_29.rrd’: No such file or directory
my configuration

Cacti Version cacti-0.8.8b-7.el6
Mikrotik CCR1036-12G-4S Firmware Version 3.27

But from another mikrotik router simple queue graph is perfectly working. so i assume its mikrotik routerboard issue. but ether queue is working with same routerboard. any idea ?

thanks

when verbose query for simple queue getting following error :

  • <arg_num_indexes> missing in XML file, ‘Index Count Changed’ emulated by counting arg_index entries

Though Mikrotik - Queue - Simple query status is success. please help
