The problem is when you select & create the graphs in cacti. The poller never executes for this template. There is no mention in the cacti log of this ever running (right, wrong or indifferent)
Seeing how there is no output at all there is nothing for me to go on. There is also nothing logged in the query_eva.log during a poll. I am quite comfortable troubleshoting errors when there are errors. Any help would be appreciated

I can manually run the commands as root, cacti, or apache and get results...and the files in /var/tmp/cacti get updated
However when I click Verbose Query for Debugging it appears as if the python scripts aren't being run...and the files in /var/tmp/cacti are not being updated.
HELP!!!

The manual wmic commands return the requested data.
The commands listed in the verbose query window of cacti return the data if executed manually.
But cacti keeps saying it has 0 items, 0 rows. I have tried re-installing, everything.
In my opinion everything seems to be in working order, but the template in cacti does not understand how to parse the data received from the query?
Hopefully the original creator can come in and fix the script somehow? I'm trying to do a readout of an EVA8400.
--------update--------
Thus far with my limited scripting/programming knowledge I have been able to determine that the python script actually never gets called.
When I manually enter a query such as : python /var/www/cacti/scripts/query_wmi.py --host umchpsim01 --authentication-file /etc/cacti/umchpsim01.pw --class Win32_PerfRawData_EVAPMEXT_HPEVAVirtualDisk query Name
I see the output of the script appear on my screen and the /var/log/cacti/query_eva.log is updated with the logging information. When I do a query in cacti, or a verbose query, nothing gets added to the log files. That leads me to think that the cacti is actually never running the python commands, even though it says so with the verbose query.
Err..... still at a loss sadly enough, but that does pinpoint where the problem is located. Anyone?
My situation was different in that I actually recieved the data when running the query in cacti. It was when the poller ran the data query seemed to be bypassed altogether.
Is the query appearing in your poller cache. (system Utilities --> View poller cache , Select the host) ??
First off...thanks for your help Lalbee99 and others!!!
Yeah, I can run it from the CLI as the Apache user and my Cacti user (data returned is EVA01):
[root@itsys ~]# su cactiuser
[cactiuser@itsys root]$ python /var/www/html/cacti/scripts/query_wmi.py --host cv01.sample.domain.com --authentication-file /etc/cacti/cv01.sample.domain.com.pw --class Win32_PerfRawData_EVAPMEXT_HPEVAStorageArray index
EVA01
[cactiuser@itsys root]$ exit
exit
[root@itsys ~]# su apache
bash-4.1$ python /var/www/html/cacti/scripts/query_wmi.py --host cv01.sample.domain.com --authentication-file /etc/cacti/cv01.sample.domain.pw --class Win32_PerfRawData_EVAPMEXT_HPEVAStorageArray index
EVA01
bash-4.1$ exit
Still nothing in the Poller Cache and the Device Associated Data Query still lists: Success [0 Items, 0 Rows]
Here is the output from a Verbose Data Query:

I was able to get the poller to recognize my data query by doing the following:
Enabling snmp version 1 with a default community of public (even though it was not in use on my eva)
SNMP Version
Choose the SNMP version for this device.
One last thing to check is the poller_reindex table. I noticed my device id (eva) was listed in the table.
select host_id,data_query_id,action,op,assert_value,arg1 from poller_reindex where host_id='XXX' ;
I deleted the entry and I was working...
delete from poller_reindex where host_id='XXX' ;
My cacti instances is running on freebsd 7.3 upward. I'd like to use cacti to monitor my hp eva 4400 SAN but it seems a key piece of the puzzle, the wmic utility has no compiled binary available for freebsd. I also cannot seem to find an equivalent utility n the freebsd ports tree Short of making heavy modifications to the wmic source code and recompiling to run on BSD, would anyone know if there are either of:
a) drop in replacements for wmic on freebsd
b) a freebsd wmi-client offering similar functionality
I have been monitoring my EVA now for some time and things look great! But... I created a new diskgroup and now i want to monitor this diskgroup aswell.
When i open my host, i can see all the way down the queries. When i do a manual verbose query i see the following:
+ Running data query [11].
+ Found type = '4 '[script query].
+ Found data query XML file at '/var/www/html/cacti/resource/script_queries/eva_physicaldiskgroup.xml'

For some reason i don't get any output, no items or devices are found. When i start the command 'python /var/www/html/cacti/scripts/query_wmi.py --host monitor.asp.local --authentication-file /etc/cacti/monitor.asp.local.pw --class Win32_PerfRawData_EVAPMEXT_HPEVAPhysicalDiskGroup index' manually on my shell, i get a proper output:
