- Help -
I thought there was a fix for this problem mentioned in the forum but I didn't find it again.
Adding and saving CPU Usage Data Source for this example doesn't help.

| UPDATE: It seems that "CPU Utilization" and "Used Space" on all of the hosts I am monitoring are no longer graphing data. This includes the Unix servers that I monitor. "Processes" and "Traffic" are still graphing. This is really weird.

Is it possible that one of your MySQL tables has become corrupt? I can't think of any reasons why you would lose all of your graph items at once any other way. Definitely try running a 'myisamchk' on the 'graph_templates_item' table. It wouldn't hurt to run a check on your whole Cacti database though.

It looks like I got bit by the Graph Save Item bug after following Chapter 12 in the manual on "Simplest Method of Going from a Script to Graph". I applied the patch and tried fixing the database but nothing was working. So, I dumped the database, installed a new version of cacti and patched the template.php file. I then went back and recreated one of my servers that got hosed and went back and went through Chapter 12 again. Looks like everything is working now. Oh well.
