cacti-0.8.8b: Multiple COMMENT arguments in "rrdtool graph"

[tkshamburg]

Hi,

after upgrading to 0.8.8b we have problems with some thumbnail graphs.
In the logfile we found:

/usr/bin/rrdtool graph - --imgformat=PNG --start=1375857758
--end=1375944158 --title='spruce.ham.foo.bar - Errors - Gi1/0/2
Out-of-band-Mgmt via n@work' --rigid --base=1000 --height=100
--width=300 --alt-autoscale-max --lower-limit='0' --no-legend
COMMENT:"From 2013/08/07 08\:42\:38 To 2013/08/08 08\:42\:38\c"
--vertical-label='errors/sec' --slope-mode --font TITLE:7: --font

COMMENT:'' AREA:cdefbh#8F9286FF:''

This results in "ERROR: Expected some arguments after 'COMMENT:'" and no
thumbnail displayed.

Why are there three COMMENT-arguments in this command?? The thoird one (empty COMMENT) results in the error.

How can we fix it?

This has been reported to the mantis bug tracker as well. The patch is available there and I will attach it here.
We are planning to publish a fixed version, soon (for those who do not like to use the "patch" command)

This rrdtool statement does not show any error (apart from the issues caused by the thold plugin). How does the graph look like?

I got the same error in graph D & F after I installed the ApacheStats_0.8.2 template. I tried the patch in cacti directory but I've got the following error message.

Perhaps you used the wrong -p or --strip option?

patch -p1 -N < cacti088b_empty_comment.patch
==========================================================================

So in which directory were you standing while applying this patch? Your -p level was wrong, or you were completely in the wrong location. Until you applied the patch correctly, don't expect this issue to resolve itself.

Thanks for your remind. I messed up my testing environment before. The patch can be apply without problem.

To fix the no thumbnail graphs showing when checking the thumbnail box.

THANK YOU to user sdavied for posting a patch file in another post. What some people may be missing that are relatively "novice" users of Cacti is how "exactly" to apply it.

If you installed the EZCacti use the Cacti WebAdmin at http://<ipaddress>:10000 in a web browser and go to the "Upload and download" topic on the left colum. Here is where you upload the patch to your server that user sdavied uploaded earlier. Upload the patch file to the directory /var/www/html Remember this does not apply the patch, it only sends it to the server.

You can use the SSH tool in the WebAdmin that you just used, but I find it easier to go the terminal of your server either sitting right at it or by ssh. Issue the command cd /var/www/html and hit return. It should return to a prompt with html in it. Then type patch -p0 -b < rrd.php.patch and hit enter. This should return to the same html prompt that you were just at.....with no errors.

That's it. Go back to your Cacti webpage and do a page refresh and click on the "Thumbnails" checkbox and you will see your graphs again for the first time in months !

Just in case I attached sdavied file from a previous post.

Hope this helps a lot of people....it worked for me.
