Monitoring performance of an HP EVA SAN

[robmize]

Not sure if you are still trying to get this to work, but I had the same problem as you. I wanted to post my solution in case anyone in the future runs across this...

My problem was that SELinux was enabled and preventing apache from executing the python script. I had the same debug messages claiming that it was executing the query, but no results and nothing in the logs. I disabled SELinux and it started to work.

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:

+ Running data query [16].
+ Found type = '4 '[script query].
+ Found data query XML file at '/var/www/html/cacti/resource/script_queries/eva_virtualdisks.xml'

Hello

I have result error with hash format when I try to import the template to Cacti

parse_xml_hash ERROR wrong hash format I have Version 0.8.7i

How to solve this? Do anyone have another template?

Thank a lot

I have tested this on centos 5 and centos 6

There is no grapg generated.
/var/log/cacti/query_eva.log is empty

I get text in log if I press green circle in Associated Data Queries.
There is:

Code: Select all

python /usr/share/cacti/scripts/query_wmi.py --host servername --authentication-file /etc/cacti/servername.pw --class Win32_PerfRawData_EVAPMEXT_HPEVAVirtualDisk num_indexes

ERROR: unknown option num_indexes

There is not EVA Graph templates in drop-down list at Associated Graph Templates.

If I run:

Code: Select all

wmic --namespace='root\CIMV2'  --authentication-file /etc/cacti/servername.pw //servername "SELECT * FROM Win32_PerfRawData_EVAPMEXT_HPEVAStorageController"
CLASS: Win32_PerfRawData_EVAPMEXT_HPEVAStorageController

(null)|Description|Frequency_Object|Frequency_PerfTime|Frequency_Sys100NS|Name|PercentDataTransferTime|PercentProcessorTime|Timestamp_Object|Timestamp_PerfTime|Timestamp_Sys100NS
(null)|(null)|0|0|10000000|FIRMA_EVA_1:PAFUBA19SWC0AD|1|1|0|0|130258985916460000

Or:

Code: Select all

wmic --namespace='root\CIMV2'  --authentication-file /etc/cacti/servername.pw //servername "select Name from Win32_ComputerSystem"
CLASS: Win32_ComputerSystem
Name
SERVERNAME

There is also error in RRDTool (See image)
On one compueet there is onlt QueueDepth source available, and on other none.

There is the reason why import template is failing.

If you change this type to anything else it will import that template with no errors. However i don't have any clue what will happen if i change this type value to 5 or 4.

[yjbenigni]

Thank's JaTe for your help.

When i change <type>5</type>
the message :
Error: XML parse error.

I look for a cacti_host_template_eva_commandview.xml file

or zip archive ...

Best regards

Hello,
@JaTe, after several modification, it's good for me. Import template OK !!!
<type>3</type> was the last test.

Thank's for your help.
