Blank graphs...

[steph1978]

Hi There,

Been having some trouble with a freshly installed Cacti as all the graphs are generated with no data. Cacti is currently running in debug mode but I’m not seeing errors indicating any specific problems. I’ve installed Cacti a couple of times on many other platforms and this is the first time I’m actually experiencing any issues with it. I’m most certainly missing something incredible stupid or overlooking something I’m considering as insignificant but I’m honestly out of ideas.

Software versions I’m using.

Centos 5.4
RRD-Tool 1.3.8
Cacti : 0.8.7e

My configuration is as follow:

RRDtool Utility version : RRDTool 1.3x
poller : cmd.php (Tried spine , same problem)
Folders rra and logs uses my cactiuser rights.


Cron is setup as follow
*/5 * * * * cacti php /www/reports.bbi.co.bw/html/poller.php > /dev/null 2>&

Output for when I run my poller.php manually in debug mode. It’s currently only setup to check localhost (CPU / Disk etc) plus a Cisco Router with 4 Interfaces and CPU utilization.

[cacti@localhost html]$ php poller.php -d

Also , cacti is installed on a virtual host running on Xend… not sure whether this causes any issues. Firewalls and SELinux is turned off.
Any suggestions would be greatly appreciated.

The first two lines from your log show the error. There has been too much time between polling events. So either your system time has a problem (formerly know to be found quite often on virtual machines) or your crond. Please see e.g. /var/log/cron for more
R.

I think the reason the error showed was because I executed the poller manually shortly after cron fired it.

This is my cron log , everything seems ok and the time on my server appears to be correct.

Apr 22 16:40:01 localhost crond[28239]: (root) CMD (cacti php /www/reports.bbi.co.bw/html/poller.php > /dev/null 2>&)

Apr 22 16:45:01 localhost crond[28253]: (root) CMD (cacti php /www/reports.bbi.co.bw/html/poller.php > /dev/null 2>&)

Apr 22 16:50:01 localhost crond[28267]: (root) CMD (cacti php /www/reports.bbi.co.bw/html/poller.php > /dev/null 2>&)

Apr 22 16:55:01 localhost crond[28284]: (root) CMD (cacti php /www/reports.bbi.co.bw/html/poller.php > /dev/null 2>&)

Please change

cacti php /www/reports.bbi.co.bw/html/poller.php > /dev/null 2>&

to

cacti php /www/reports.bbi.co.bw/html/poller.php > /www/reports.bbi.co.bw/html/log/poller.log 2>&1

and have a look at that file
R.

[steph1978]

Thanks for the help man , seems like cron didn't like it when the cactiuser where put at the beginning of the command.

Before (added as root)
*/5 * * * * cacti php /www/reports.bbi.co.bw/html/poller.php > /dev/null 2>&

Seems to be working fine when I added the cron entry logged in as my cacti user.

*/5 * * * * php /www/reports.bbi.co.bw/html/poller.php > /dev/null 2>&

Had a feeling it's something stupid

In fact, running /etc/crontab or the like requires the user to be filled in.
Running user crontab does not require the user to be filled in
