arg_num_indexes missing in XML file

[Ahmed1993]

Hi everyone
I have been trying to add QoS template to use it with cisco router , all goes well until I added it to Associated Data Queries of the router
status show success bot 0 Items, 0 Rows so I used Verbose Query and the following came out

+ Running data query [11].
+ Found type = '4' [Script Query].
+ Found data query XML file at 'C:\Users\Administrator\Downloads\cisco-qos-64\cacti_data_query_cisco-qos-64.xml'
+ XML file parsed ok.
+ <arg_num_indexes> missing in XML file, 'Index Count Changed' emulated by counting arg_index entries
+ Executing script for list of indexes ' ' Index Count: 0

I have no knowledge in XML so can I do???
note :- I have tried two other templates but the same problem came out

Have you configured you cisco to allow the information via SNMP? By default it will be locked down.

Hi netniV
in fact I have an old working cacti server so I have mirrored configuration for the new one
I have even tried to export the QoS template used in the old cacti to use it in the new one but the same problem

On the Cisco, have you permitted the new IP to poll?

Show us the SNMP on the Cisco side please. Mask out anything you don't wish to be shown in public.

Dear camerabob ,
thanks for your interest

==> on the monitored router
snmp-server community password RO Cacti
snmp-server host 10.30.1.251 password
ip access-list standard Cacti
permit 10.30.1.251

==> on a Cisco ASA (connecting the router to the LAN containing the cacti server)
access-list ACL-X extended permit udp host 10.30.1.251 host x.x.x.x eq snmp

Cisco have a decent page on the various things you can do to monitor the use of SNMP on the devices:
https://www.cisco.com/c/en/us/td/docs/s ... _snmp.html

Try monitoring the usage. Also, make sure that the device is definitely listening for UDP traffic on SNMP by using SNMPWALK

I also have no problem in snmp on my new server since I can create graphs for my router (interface traffic and cpu) but just have a problem with templates
