Monitoring performance of an HP EVA SAN

[hapklaar]

Great work people! I will surely test your templates next week and report my findings.

Unfortunately the templates don't seem to work for me, I seem to have a version mismatch:
Error: XML: Hash version does not exist.

Using 0.8.7b as is advised for the WMI integration.

Any change these xml's can be converted to be used on 0.8.7b ?

Here's what I have so far. It's built to monitor two EVAs though the SMA. I'm using the WMI from http://www.parkingdenied.com

The host port graph description will most likely need to be modified to match the host port names.

hi,
have you this template for EVA8000? thx

palli or boatrke1, any updates? I am looking for the extension mentioned by palli, each virtualdisk.

Hi,

I try to make perl script to automate EVAPerf graphing (under Windows 2003).
Here is my first script. It run command "EVAPerf as" which give this result :

Total Total Node
Host Host
Req/s MB/s
----- ------ -------------
179 5.20 HPEVA8100S1
1601 26.07 HPEVAS1
1375 10.50 HPEVA8100S2
1163 15.26 HPEVAS2

I pass the name of my EVA as parameter :
EVA_ArrayStatus.pl -s HPEVA8100S1

which return :
HostReqS:1909 HostMbS:24.93

Then I create the datatemplate and graph template.

I'll try to make other script to collect other counter like "Virtual Disk statistics", "Virtual Disk Group Statistics", etc.

Any comments are welcome...

Kevin, what version of Cacti did you use to export those templates? I'm using 0.8.7b (like someone who posted before) and can't import the template. If we can't convert it then maybe we could know what version of Cacti we need to upgrade to.

Here are some thoughts I have on these templates, as well as some questions.

1) To get these to work, I had to change the Input String on all the Data Input Methods to:
/usr/bin/php -q <path_cacti>/scripts/wmi.php -h '<host>' -u '<credential>' -w '<class>' -k '<filter>' -v '<filterval>' -c '<columns>'

It was missing the flags (-q, -h, etc) in the version I was working with.

2) Storage Array wasn't working, but it was because the Data Input Method was expecting output in the format of:
TotalhostKBPers0
TotalhostReqPers0
TotalhostKBPers1
TotalhostReqPers1
but mine just returned TotalhostKBPers and TotalhostReqPers

Now, for my questions. I'm the cacti person in our organization, but I know very little about the SANs themselves. What is the difference between the EVA01 and EVA02 templates? They appear to use the same Data Input Methods and Data Templates, is it just a graphing thing? I ask because both templates return graphs for my server. Except that Storage Controller and Storage Array for EVA02 don't return anything.

Thanks!

I do, i have updates! i have finished very good templates around evaperf. and dataqueries that allow you to have a graph for every virtualdisk.

I have screenshots here: http://pall.sigurdsson.is/evaperf/

However i have discovered an issue, evaperf is really REALLY unstable if counters are read regularly from WMI.

Unfortunately after weeks of discussion with HP support their reply was that they don't really support evaperf via WMI and they don't plan to fix the issues :/

hi all,

I've got wmi working as expected

Code: Select all

/usr/local/bin/wmic --namespace='root\CIMV2' --authentication-file=/etc/cacti/wmi.pw //<server> "SELECT * FROM Win32_OperatingSystem"
CLASS: Win32_OperatingSystem
BootDevice|BuildNumber|BuildType...

but once I select EVA performance data I get an error:

Code: Select all

/usr/local/bin/wmic --namespace='root\CIMV2' --authentication-file=/etc/cacti/wmi.pw //<server> "SELECT * FROM Win32_PerfRawData_EVAPMEXT_HPEVAStorageController"
ERROR: Retrieve result data.
NTSTATUS: NT code 0x80041010 - NT code 0x80041010

What's wrong? Perfmon is runing...

Thanks, Stephan

palli, I have been following your posts here and on itrc. Do you have any documentation to help get to the point you are currently at?

thanks

Hit there, I installed the packages + the Template but i dont get any data ...

Here's waht my logfiles say :

Code: Select all

manually starting the request gets :

Yes! I do. I wrote quick guidelines from the top of my head. and put them here: http://opensource.is/trac/wiki/cacti-evaperf

When i have time i will improve them, but until then feel free to download the templates and try for yourself. If you have any problems with the installation or the directions, don't hesitate to let me know.

I will probably create a new thread for these templates shortly.

Nice work dude

But Attention to all DOMAIN USERS :

1. Your authentication file has to be like this :

Code: Select all

username=*youruser*
domain=*yourdomain* (the short one without ".de, .com" etc)
password=*yourpassword*

2. also special signs like $#§%&/(=?`^ dont work as username and Password

3. the authentication file cacti uses is "/etc/cacti/HOST.pw" while HOST is the IP of the Command View server

Thanks very much!!

Thank you alphadog, i updated the documentation to more clearly demonstrate this : )

Can i assume you have the templates up and running? How do you like it?
