Hi Tom,
Here are my cron settings, and the RRD Command , and the directory listing of one of the devices in question.
I did also notice another strange item and I don’t know if it is related or not. The BGP menu item indicates that I have 56 items (which I do), however when I select it nothing appears in the resulting window.
Thank you,
Tim

Hi Tim,
If you click on "RRD Command" in that last graph, you can see the command used to generate it, and what RRDtool returned. This will help (us/you) in finding the exact issue.
However, are you sure your crontab settings are OK? If they do draw but don't show data, I suspect there is no data, and no rrd files, which mean you get draw errors...

Hi,
I recently updated to the subscription model of observium and did a clean install, but did use my old config.php file. I have several pages where the graphs show draw errors. I have tried setting the permissions on the RRD to apache:apache as indicated in the instructions, which did not seem to change the behavior. I then switched it to root:root, which also does not seem to change the behavior. I reviewed the information on RRD and Graph issues from the mailing list archives, unfortunately the couple of items I found to try did not seem to change the issue either. I did remove the ?> tag and the remaining white space at the end of the config.php file. I have attached a screen shot of the current permissions for the RRD directory and a screen of from one of the pieces of equipment showing the draw error. Some graphs appear to draw but do not contain data such as the CPU graphs.
I am not sure how to proceed to further isolate what may be wrong. I have verified the path to the RRD directory and Executable on the system and checked that they were good in the config.php file.
Thank you,
Tim
