Empty Graphs?

[hyloth]

My graphs -seem- to be getting created just fine, but every time I go to look at a graph, the displays always read "nan" on any graph, for any value. What am I doing wrong?


Thanks much

Check permissions on /rra

[hyloth]

Permissions are as follows:

drwxrwxr-x 2 cacti webdev 4096 Mar 1 13:38 rra

[egarnel]

Also, are the rrd files being updated?
If you go under console and turn on the graph debugging, it may shed some more light on the subject

is webdev your httpd server group and/or is the web server user in that group (typically apache or nobody under unix)?

[egarnel]

Per the docs, rra & log should be owned by the cactiuser

[hyloth]

webdev is my user that runs the webserver, which the username "cacti" is a part of. /rra is owned and read/writable by cacti. The RRA files don't seem to be getting updated unless I manually run php cmd.php (Just realized thats because I had the wrong path in crontab) ...

But even when I run the cmd.php manually, it doesnt seem to update the graphs with any values other than "nan"...

[egarnel]

Who are you running the cmd.php from the command line as?

[hyloth]

I run the command as cacti, via this command:

Code: Select all

su -u cacti php cmd.php

and it displays the following:

jomamma:/usr/local/apache/htdocs/cacti# sudo -u cacti php cmd.php
command: perl /usr/local/apache/htdocs/cacti/scripts/linux_memory.pl MemFree:, output: 12552

update /usr/local/apache/htdocs/cacti/rra/localhost_proc_7.rrd --template proc N:105

And the rrd/* files all get an updated timestamp.

did you ever solve your problem, I have the same thing that the graphs don't show any data but when I run cmd.php manually I see all the scripts returning values.

[egarnel]

Can you post the output of ls -al rra as well as ls -al log?

[Guest]

Hi,

got the same Problem, i'm kinda wiered about all the forum threads which already care about it, but never they come to a clear solution...

Here is my ls -al of rra/

Code: Select all

[root@RHLinux8nbg cacti]# ls -al rra
insgesamt 444
drwxr-xr-x    2 root     root         4096 Jul 13 12:41 .

-rw-r--r--    1 root     root            0 Jul 13 10:59 .placeholder

and here of log/

Code: Select all

[root@RHLinux8nbg cacti]# ls -al log

drwxr-xr-x    2 root     root         4096 Jul 13 11:24 .

-rw-r--r--    1 root     root        83232 Jul 13 12:50 rrd.log

cacta is the user that calls the cmd.php in the crontab file

Code: Select all

#Cacti
*/5 * * * * cacta php /usr/local/apache2/htdocs/cacti/cmd.php > /dev/null 2>&1

there IS something wrong with the permissions, i figured that from other threads allready

Thanks for your help folks

I think i solved the problem.

i installed everything again, clean. (Apache, php, mysql, cacti)
all as root (i know its insecure but its working )

i just start EVERYTHING as root, including te cronjob.

my cronjob looks exactly like in the docu, but i REPLACED the 'php'command with the COMPLETE path to the php binary (/usr/local/bin/php) .

i gave the whole cacti-directory ownage for root:root .

and now it's working fine, as it should.

i will try to get it working as normal user next week, let's see what it'll bring...

I'm having the same Issue... Any updates?
