Graph image HEX Characters & Zoom issues
Hello,
Just setup Cacti more or less following these instructions except Mysql instead of MariaDB:
https://www.howtoforge.com/how-to-insta ... ntu-20-04/
Having an issue where the graph images are showing weird Hex characters inside rectangles instead of text. I've seen someone else had this issue with no resolution.
Also not seeing any way to zoom in on the graph.
Any help would be appreciated..

The latest. 1.2.26. First I tried from ubuntu packages but that gave me an older version..
I'll give those instructions a try, but very similar to what I had tried.
Thanks...

Try to change Configuration -> settings -> general -> RRDtool version
Try to change Configuration -> settings -> Visual -> Font selection method
Show management -> graphs -> choose any -> Turn on graph debug mode -> show rrdtool command
You can try run this rrd command in shell, maybe you get any warning/error:
/usr/local/bin/rrdtool graph - \
--imgformat=SVG \
--start='-86400' \
...
...
GPRINT:cdefe:MAX:'Maximum\:%8.2lf %s\n' > something.svg

Re: Graph image HEX Characters & Zoom issues
Thanks Macan.
It was this setting that resolved the issue:
I changed it from "Theme" to "System", thanks for the help.
The only other issue I see is that I cannot zoom in on a graph - I'm assuming I should be able to?
tks...

Re: Graph image HEX Characters & Zoom issues
zoom - try another browser, clear cache

Re: Graph image HEX Characters & Zoom issues
Thanks for the suggestion but that (browser/cache) did not work. There are no icons to click for zooming, and if you double click the graph image, nothing happens. Right clicking the graph brings up the same menu you get right clicking any image. If I try to select a subset of the time in the graph by left clicking and dragging across the graph - it just drags the whole image..

Re: Graph image HEX Characters & Zoom issues
Something to do with RRDtool and SVG output. Try switching to PNG for your templates and see if the output is better. Use RRDtool 1.8 if possible.

For those wondering, I'm still here, but lost in the shadows. Yearning for less bugs. Who want's a Cacti 1.3/2.0? Streams anyone?
