Empty values when script is executed by poller

[ogeeen]

Hi,
I am using esxiograph.sh script to monitor our Virtual hosts on VMWare ESXi.

The problem is that when the script is executed by poller then in cacti log I see only empty values:

Code: Select all

12/14/2015 06:25:15 PM - SPINE: Poller[0] Host[46] TH[1] DS[4847] SCRIPT: /var/www/domains/default/htdocs/cacti/scripts/esxiograph.sh mem_vm xx.xx.xx.xx esxihost vmname PASSWORD, output: usage: active:

But when I run the script manually, then everything seems ok:

Code: Select all

root@monitoring:~#/var/www/domains/default/htdocs/cacti/scripts/esxiograph.sh mem_vm xx.xx.xx.xx esxihost vmname PASSWORD
usage:1016.04 active:102.40root@monitoring:~#

Also when script is executed by cacti user:

Code: Select all

root@monitoring:~#su -c "/var/www/domains/default/htdocs/cacti/scripts/esxiograph.sh mem_vm xx.xx.xx.xx esxihost vmname PASSWORD" cacti
usage:1016.11 active:81.92root@monitoring:~#

Does anybody have any idea why should script executed by poller return empty values?
How can I debug this issue?

Thanks for help.

Update:

When I run the poller as root, then the script works amd returns right values:

Code: Select all

*/5 * * * *    root   /usr/bin/php /var/www/domains/default/htdocs/cacti/poller.php > /dev/null 2>&1

So the access rights are wrong somewhere.

Does this also work ?

Code: Select all

su -l -c "/var/www/domains/default/htdocs/cacti/scripts/esxiograph.sh mem_vm xx.xx.xx.xx esxihost vmname PASSWORD" cacti

If not, then it's an environment/path thing. If you skip the "-l" then the su command will use the path/environment variables which have been set by/for the root user.

So your cacti user may miss some path and/or environment settings.

It works. No difference between running the command woth or without -l.


Thanks for your answer.
