I just got hit with this bug on 0.8.8a, but mine is not a fresh install, it is quite old ... it would not update the RRDs... I put in DEBUG mode, but did not see any relevant messages in the logs ... after a while I did change to cmd.php and then I sawgandalf wrote:Status "unknown" is default for devices with no associated Graph Templates|Data Queries|Poller Item entries.
Please post XML to get an idea why nothing is entered into Poller cache

POLLER: Poller[0] NOTE: There are no items in your poller for this polling cycle!
After this I went in the 'system utilities' and did a 'rebuild poller cache'... after that voila, it started work again.
First time I saw this on 5 years of running cacti ... I did enable the realtime plugin two days ago, but it should not be related to that.
Let´s see when it happens again... if anyone has any tips, let me know.
thanks!
