Untemplated Data Sources can fail to update due to lack of an assigned Graph #5384
Description
Describe the bug
Starting in Cacti 1.2.24, Cacti started looking at the Graph assignments for Data Sources so as to reduce the amount of storage required for RRDfiles. If there was a Data Source in that Data Template that was not used for a Graph, don't create and RRDfile for it. However, this approach will break the behavior of Stand Along Data Sources as they are created independent of the Graph Template.
To Reproduce
Steps to reproduce the behavior:
-
Manually Create a Data Source mapped to some Data Input Method
-
Watch the Cacti Log for errors like entries left in the poller output table for that new Data Source
Expected behavior
Cacti should properly handle this special case of Data Source properly.
