Please explain what you did and what fails; error messages would be lovely. Better: read 1st link of my sig to find lots of HowTos. Please ask if anything is unclear

There are multiple reasons for this. Mostly, the "downed host detection" for that host failed. This is a "per host" setting. E.g. if you selected PING method and are not running as root, ping will fail (always fails due to lack of permissions) and no rrd files will be created.
Please see debugging procedure at 2nd link of my sig

Unfortunately, that's no news. Please see poller debug log (file cacti.log) to find out, whether the poller detected that host as "down" during polling

Those errors are bad. But you may simple try to run cmd.php or better spine against a single host only to keep logs at bay.
I'm quite sure, if gethostbyname fails, cacti will see the host as "unreachable" and will neither poll nor create an rrd file

There are templates, but perhaps not for 086i (I created some of them on my own, lately)
