[rrd-users] Re: Strange RRDTool Image File Behavior

[Warnes, Jason SDH]

Is that the error from the RRD Tool command line?  If it's the error capture
by the Perl RRDs module then I'm not sure if this will help, but when I'm
writing my Perl scripts for NT I need to use the \ slash when specifying
file systems, not the / slash that is used in UNIX.  In my Perl scripts on
NT I actually need to use a \\ everytime because the \ is an escape
character for text formatting.

I'm probably way off base here, but it was something I noticed...

Jason...

RRD shows the following error when trying to create the new image file:

"Opening '../filename.gif' for write: Invalid argument"

This doesn't halt my PERL program, it continues on to the next step.

When I attempt to manually delete the files, they will disappear from
Explorer (until I "refresh" or re-run my search).  The file is not being
recreated, it still has a modify date that is not current.  If I try to
delete from a CMD prompt, I get no errors, but when I DIR again, it's still
there.

The permissions on the directory where all of the image files are being
stored are as follows:

Domain Admins: Full Control
My Account: Full Control
Everyone: Read

It was intentionally setup this way because of the access by the user
community to this server...I didn't want just anyone to have more than
"read" permissions.

"Cannot be replaced".  Does this mean that RRDtool stops with an error?

"reappear".  Could it be that they *are* recreated?  If this happens right
away, could there be a tight loop where RRDtool is called over and over
again?

Is this true?  It works this way for root on unix but IIRC you don't need to
permit the admin group anything if you don't want?  The admin may steal your
file (change ownership) but this doesn't mean the file can be
read/changed/whatever prior to that?
