Needing help to setup a simple Perfstack graph from a custom poller

Hi,

We updated the firmware of our Sophos Firewall and the snmp value for Live Users changed and the Perfstack widget graph sopped to work.

I am trying to create a custom poller with the MIB 1.3.6.1.4.1.2604.5.1.2.6 (sfosLiveUsersCount). I have tested it and it return the current number of open sessions.

I created the poller and assigned to the node.

The gauge and the graph are displayed on the details page of the node, but it is not available to insert into a Perfstack widget. I would like to add the widget on our main summary page liek we did with the Cisco ASA firewall.

Thanks for your help.
