cacti + not plotting graphs

Post by aeby »

Hi all,

i have installed cacti but instead of displaying the grpahs it gives me a page with the following errors. I cant figure out why the graphs are not being plotted.




/usr/bin/rrdtool graph - \

--end=1188223131 \

Please read careful installation instructions given at http://docs.cacti.net/node/5. And please post a screenshot of the failing graph along with version info for cacti, rrdtool, mysql, php, snmp. Make sure, cacti is fully patched http://www.cacti.net/download_patches.php

Please have a look at http://docs.cacti.net/node/411 for help on correct setup of snmpd. Then, please try to use "ucd/net SNMP Host" Host template instead of "local Linux machine" and retry

Hi gandhalf,
the snmp error is gone but still it doesnot want to plot,it gives me the same page as before. i added a device and turned the debugging for the graphs. on it gives me the following error.


ERROR: opening '/var/www/html/cacti/rra/testmachine_load_1min_35.rrd': No such file or directory.
i checked the permission on the rra folder it is owned by cacti user
drwxr-xr-x 2 cactiuser root 4096 Aug 29 10:26 rra

how do i fix this. what else should i look into.
cacti is not creating files in rra ..?????????????????

Thanks gandhalf.

Hi Gandhalf,
i have not installed php-cli, i am running FC2 and i it is not installing via yum , it is running php-4.3 version,
but on another version running Centos 5 i manually ran php -q poller.php and it is generating the .rrf files and i have installed php-cli it is running on php-5., but the cron is not running, and i am able to see empty graphs .
is it coz the php-cli package is not there that it is not genertaing the .rrd files,

how will i get to generate the rrd files.

please advice
thanks for all the help

Unless the following procedure produces reasonable output, you won't see anything:

Code: Select all

login as cactiuser
cd to the cacti directory
run "php -q poller.php"
Now, you should see reasonable output. If not, I suppose your php is broken

You must login to see signatures. If you installed from rpm/yum/apt-get, please search /etc/cron.d/cacti
