bash script not populating rrd

[chk9]

Newbie question.
Running Version 0.8.8b on Ubuntu 14.04

I've created a new data input method using the following poller.
My poller provides the following data:

Code: Select all

~$ b/vera-cacti-poll.sh eth0.2
rec:81262822953 snd:7102042602
~$ 

The poller cach shows:

Code: Select all

Vera WAN  Script: /bin/bash /home/chris/b/vera-cacti-poll.sh eth0.2
	       RRD: /var/lib/cacti/rra/rec_8.rrd 

However the cacti log shows:

Code: Select all

09/16/2014 01:05:01 AM - CMDPHP: Poller[0] Host[0] DS[8] CMD: /bin/bash /home/chris/b/vera-cacti-poll.sh eth0.2, output: U
09/16/2014 01:05:01 AM - CMDPHP: Poller[0] Host[0] DS[8] WARNING: Result from CMD not valid. Partial Result: U 

What am I doing wrong?

Could be multiple different things. First check these.

1. Permissions, make sure the poller user has permissions to execute that script
2. Selinux, its a pox
3. Check the commands inside the script, the poller user needs permission to run any commands in there too.

[chk9]

Hmm does not looks like it's a permission issue:

Code: Select all

~$ sudo su www-data
[sudo] password for chris: 
$ /bin/bash /home/chris/b/vera-cacti-poll.sh eth0.2
rec:81332368296 snd:7127901568

Not sure where to check selinux issues

[cigamit]

Code: Select all

setenforce 0

[chk9]

Ok found out selinux is not active:

Code: Select all

~$ getsebool selinuxuser_ping
getsebool:  SELinux is disabled

And running from the command prompt it works!

Code: Select all

~$ sudo su www-data
$ php /usr/share/cacti/site/poller.php --force --debug

It shows in the cacti log now:

Code: Select all

09/18/2014 08:30:15 AM - POLLER: Poller[0] Parsed MULTI output field 'snd:7300759405' [map snd->snd]
09/18/2014 08:30:15 AM - POLLER: Poller[0] Parsed MULTI output field 'rec:81796546621' [map rec->rec] 

And on the graph

But why does it fail from within cacti?

Code: Select all

09/18/2014 08:35:01 AM - CMDPHP: Poller[0] Host[0] DS[8] WARNING: Result from CMD not valid. Partial Result: U 

[chk9]

Anyone with another suggestion how to solve this issue?
Any debug tips to try?
I'm not getting the difference between the scheduler from within cacti and cron?!

I got a work around for now, by adding the poller to a cron job, but it's not as it should be setup:

Code: Select all

# m h  dom mon dow   command
*/5 *  *   *   *     sleep 5 && php /usr/share/cacti/site/poller.php --force --debug

Cacti log:
