ERROR: opening ...... : No such file or directory

Guest · Post by **Guest** » Wed Sep 01, 2004 4:43 am

Hello, all. I am having another issue here, maybe due to my own fault, who knows.

I keep getting the below error when trying to graph HDD space when using the ucd/net Available Disk Space template. I've seen an error such as this before, and I never did end up getting it resolved. I am unable to figure out what's wrong here.

Permissions are in check, and I do believe that they're fine. My cacti user does have permission to write to rra/ and log/, it's just that the file itself is not being created. Many other graphs are created without incident.

What is the cause of these errors?

Even though this is 0.8.6, I remember seeing it in 0.8.5, as well. I was very suprised when I didn't find many postings about this error, as I thought it was a fairly common question.

Thanks!

So no one has seen this before? Surely it has been an issue in the past for some of you.

Thanks

It would be helpfull if you would attach your logfile. Clear your logfile and then goto settings->general, turn logging to DEBUG for one polling cycle. Attach the logfile to this thread and then we can talk. When you simply talk about having problems and looking for help without supporting detail, you kind of look ???

Yeah, I appologize for that...

Ok, so here I go:

First I went into Graph Management, made sure that this was not already being graphed (deleted all data sources and graphs, yada yada), because I had been toying with it earlier. I disabled all of the hosts except for one to test with, to make looking through the log easier. Then I proceeded with the following:

Devices -> My Host -> Add Graph Template: Host MIB, Available Disk Space -> Add -> Save -> Save again, for good measure -> Create Graphs For This host -> Checkmark the box that I wanted to graph -> Create -> Create Again (ignoring Custom Data) -> Create Again for good measure.

While doing this, I did not notice any data placed into the debug log, which I figured was kindof odd. But then, I watched the log more, and this appeared:
