ERROR: creating arguments

[pianograndpulp]

Just did an upgrade to 1.2.9 from 1.2.3 and everything seems to be running fine except the actual image making of the graphs. I'm getting an "Error: creating arguments" picture instead of the graph:



My RRDtool Command is:

RRDtool Says:
ERROR: creating arguments

However - if I run that on the command line it outputs an image just fine... I've checked permissions, etc. - not sure what else to check.

I'm running RRDtool 1.4.8 on Centos 7.

Edit - found this in RRDtool if it helps:

Code: Select all

if ((argc = CreateArgs(argv[0], aLine, myargv)) < 0) {
                printf("ERROR: creating arguments\n");

Thanks!

Generally speaking that means a mismatch of quotes which I suspect may have something to do with the title of the graph.

[pianograndpulp]

Appreciate the response. It’s happening for every one of my thousands of graphs. When I ran debug the actual call to RRDtool was slightly different than what the UI shows as the command. But even when I ran that command locally - it output a graph to the file system. Will keep digging for what is exactly being passed during the RRDtool process.

Thanks!!

Found out the issue... it was my font. Specifically - Queenie's - with an apostrophe. It worked fine in 1.23 - somewhere along the line up to 1.28 and 1.29 - the way fonts are being referenced in the output it's failing. I can't reference it by file name... And escaping the apostrophe doesn't work either. Using the rrdtool graph command on the command line prints out the graph correctly with the correct font. For now I've switched to another font. I'll open up a ticket on Github.

Thanks!

Yeah, that would be good as we should be handling that correctly.

Hi,

I found that thread after i run into a similar problem, but in my case, it has nothing to do with fonts, I assume.

What I did: I upgraded Cacti from 1.1.38 to 1.2.10 as I use the version from Ubuntu - there I did upgrade from 18.04 to 20.04 which leads to the Cacti upgrade.

Everything went smooth, poller is running fine after upgrade, rrds are updated - only thing is, that every graph, also new created graps end with the picture "ERROR: Creating arguments".

Taking the textoutput from Graph debug and enter it manually on command line draws the graph without problems.

How can I fix this?

[GTY71]

I found out, that if I remove the watermark, all graphs are rendered fine - so there is something wrong with Watermarks in may installation.
I have running the same Ubuntu and Cacti version running on another server where watermarks are working.

Any idea?

[GTY71]

For anyone who also runs inti the same problem...

Removing the apostroph (') from the watermark text fixed this behaviuor and all graphs are rendered and displayed fine.

You can also replace the vertical apostroph ' by another one - ` or ´ - this also works fine!

[Osiris]

Good catch. Can you log a bug on GitHub?

Sorry, but where should I do it? I can not understand.

You can set it under Configuration -> Settings -> Visual: There you find the line "Watermark Text"

Sorry, but i found it. But i can not understand what should i write there....
By default this field doesn't contain an any apostroph. I tried to use `, ' and ", also i tried disabling watermark and no effect....
