[solved] Cacti not generating graphs

[noshybabs]

Hi everyone,

Let me start by saying im a complete noob with cacti. Ive used it quite a few times to diagnose problems and think its great, but ive never had the plesure of installing it before, so im sorry if my issue is something obvious.

I dont seem to be getting graphs generated in cacti. If you go to the page you just get the little red cross.

I looked at the config of one of the graphs in debug mode and i get this

RRDTool Command:

C:/rrdtool/rrdtool.exe graph - \
--imgformat=PNG \
--start=-86400 \
--end=-300 \
--title="Leeds-Vapp01 - Processes" \
--base=1000 \
--height=120 \
--width=500 \
--alt-autoscale-max \
--lower-limit=0 \
--vertical-label="processes" \
--slope-mode \
--font TITLE:12: \
--font AXIS:8: \
--font LEGEND:10: \
--font UNIT:8: \
DEF:a="C\:/Inetpub/wwwroot/cacti/rra/leeds-vapp01_proc_9.rrd":proc:AVERAGE \
AREA:a#942D0CFF:"Running Processes" \
GPRINTLAST:"Current\:%8.0lf" \
GPRINTAVERAGE:"Average\:%8.0lf" \
GPRINTMAX:"Maximum\:%8.0lf\n"
RRDTool Says:

ERROR: opening 'C:/Inetpub/wwwroot/cacti/rra/leeds-vapp01_proc_9.rrd': No such file or directory


Does anyone have any ideas as to what i can do?

Thanks

Im so confused, it looks like the graphs are being generated, but there is nothing in the RRA folder?

COuld it be that the data isnt present?

Ive fixed it.

It was something very easy. the scheduled task didnt have permission to run...D'oh!

I am having the same problem, exact same situation. Where did you change the permission from to allow the scheduled task to run???

Kind Regards

Likely by editing the scheduled task. If you turn log to MEDIUM, you should see log messages rolling into the Cacti log. If not, then your scheduled task is not running. In addition, if it's running and you are not getting your RRDfiles either created/updated, then it's a file permissions problem.

OK, turned it to medium, have checked cacti log files and have noticed the only actions logged are the ones I tried running manually so it is not running the scheduled tasks, however I can't seem to find the place to set the scheduled tasks.

Sorry about this, but where can I start or adjust the scheduled tasks??


Thanks

Use Google. There are millions of examples as to how to do such a thing. True Understand Begins... If you don't conquer your lack of understanding by first learning, you will never be happy with Cacti or anything else in life. Life and/or Cacti is not spoon fed. For Cacti, we give you the spoon, you have to eat.

Thank you. I have adjusted the poller interval timing but it isn't running as scheduled. I thought there might be some where else to adjust the scheduled tasks.

But thank you, sometimes I do get lazy and need to be told to think a bit harder so I will but if I get no where I shall be back.

Found the problem, it was that the slashes were the wrong way round under the paths tab in the settings.

They were forward slashes instead of backslashes. This was the problem, but I didn't think it was because it was saying "path found" under each field so I didn't think it mattered.

Ran the poller.php and php.exe files manually and it has now created the graphs in the rra directory. Thanks for all the help
