Problem with Graph generation

Post by Amadeus »

Hi,

I am kinda new to cacti. Jus got to install it on RHEL 4 and added couple of devices.

The problem that I face is that when i go to the tree view and select any device, I am not getting any graphs. :cry:

I jus get a X.

But when I click on these i get the graphs that pertain to the device and the monitored parameter.

Again on these graphs when I click on the magnifying glass, I get that X again.

I am not sure where I am goin wrong !!

HELP APPRECIATED !!

Which browser are you using? Did you double check Settings->RRDTool Utility Version? Do you use specific rrd font files?

Hi Gandalf,

I am using IE 6.
I checked for the RRDTool version and it is correct.

I am not using any specific RRD Font files, just the default ones.

Leave it alone, if you don't want to increase your problems!
Please visit graph management for a failing gaph, switch to debug mode and post the whole rrdtool graph statement

Please copy the rrdtool graph command of a FAILING graph to some arbitrary file. Change rrdtool graph - \ to rrdtool graph /tmp/foo.png \ and run the whole command line as a shell command. Any errors?
And, please, do not post non-standardized formats. The forums allow for attaching graphs directly. That reduces my effort by far!

Hi Reinhard,

I ran the same command after changing /usr/local/rrdtool/bin/rrdtool graph - \ to /usr/local/rrdtool/bin/rrdtool graph /tmp/foo.png \
I did not encounter any error.

The output of the command was :-

597x213

and the file foo.png was created.

Sorry about the attachment last time, am kinda new and was not aware.

Last resort: Please enable debug settings for graphing commands (Settings). It will be quite verbose! Please try to find the statements associated to your failing graphs.
