System info in graph

[FredZwarts]

I am using Cacti 1.2.24.
On the main page of a device with SNMP, there is a header at the left with SNMP information: System, Uptime, Hostname, location and contact.
Apparently cacti knows how to get this information, but I wonder how to get this information in a graph. I see that for the uptime there is a data source, but if I want, e.g., the 'System' information in the header of a graph, how could that be accomplished? I see no queries for this information and also no fields in the xml files in the resources (sub)directories.

Templates -> graph -> choose any -> add Graph template item
Names are from SQL host table like
snmp_sysObjectID
snmp_sysDescr
...
