5 years ago Hi,
uloganalyser does not create the rrd files - the cacti poller does this. Even if the data source is not working it would normally create the files with NaN values in them. Not having the file suggests that there's a problem with your Cacti install. There have been some people that have installed broken releases of Cacti (newer is not always better) but a working install should have a file after the next poller cycle.
If you still think there's a problem then please follow the diagnostics described on the blog and reopen this. see https://www.pitt-pladdy.com/blog/_20151108-193119_0000_Debugging_Cacti_Problems/
Thanks Glen
When I add graph of interfaces for new added device , I got the error message below , and there isn't any rrd file created:

Does anyone met this before ?
