Data sourve, Template, errors

[eholz1]

Hello All,
I am baffled by these errors. I have 500 devices, all but 100 are disabled.
I started with one device enables, and no errors. Then added devices. Now I canm getting these errors
every time the poller runs, I have the poller set for every 5 min in cron, and doing 30 sec data collection.
Here are the errors/warnings:
2023-01-16 18:10:11 - POLLER: Poller[Main Poller] PID[11430] WARNING: Data Template 'Interface - Traffic' is impacted by lack of complete information
2023-01-16 18:10:11 - POLLER: Poller[Main Poller] PID[11430] WARNING: There are 1 Data Sources not returning all data leaving rows in the poller output table. Details to follow.

Is there any way to isolate these warnings? and fix them, etc.
This is a new install of cacti-1.2.23 - really an upgrade from cacti-1.2.19.

Any ideas here?
thanks, eholz1
