What class to check RAM or Disk usage via CIM/WBEM

BurningKrome — Thu, 08 Dec 2011 16:59:35 GMT

Hey,

How do you or CAN YOU check the RAM memory, hard drive usage or network performance data through the ESXi CIM/SMASH api? CIM (generically) seems to suuport this, but I cannot find the class/property which contains this information.

Thanks!

Adding CIM Framework functionality or classes to VMWare

BurningKrome — Thu, 08 Dec 2011 16:58:57 GMT

Thi is related to my other question about where to check the memory/hard drive usage through CIM/SMASH. I THINK this is not possible because VMWare did not implement/populate the classes required to do so. I'm hoping someone will tell me I'm wrong about that

But if I'm right...then is it possible to add this functionality to the CIM framework? I have breifed through the CIM Development guide, and get the impression this can be done. However, being new to CIM and having a deadline...there are some things I'm hoping to learn before I invest too much time trying to learn the manual.

Remembering that I'M NOT A VENDOR...and only have access to the technology/firmware/SMART/ETC. already existing in my hardware...

- Can a new class be added to the CIM framework on ESXi? BRIEFLY...how? (I don't expect a whole tutorial

- Can an existing class be told to begin querying the hardware for the information if VMWare is not already doing this?

- Is this a function of VMWare, or the hardware agent (I.e. IBMs server agent for CIM)?

- If so, how ?

Thanks!

Re: ESXi5: Hardware tab: Sensors not updating

BurningKrome — Wed, 07 Dec 2011 15:06:03 GMT

They seem to be updating now. I did not actually change anything I can think of. It may have been an issue with the client accessing the sensor data. Thanks for all the help!

Hi Abbie,

Thanks for the reply. So, actually, the more important issue may be these sensors providing the correct data when I use WBEM to access them from a remote client (I.e. my python script or another CIM Client GUI such as "CIMNavigator").

I'm using the "vpxuser" for access. I also created an administrative account named "root" which connects and reads the data OK, but (again...still) the data does not update. When I'm looking at the Configuration tab...I'm using vSphere client from a remote windows box. In fact, we don't even have vCenter installed (and are hoping to avoid the need for it).

Which user should I be accessing the CIM data with? Or do I need to create a specialized client? If so, with what settings?

Thanks again for al the help!!

ESXi5: Hardware tab: Sensors not updating

BurningKrome — Fri, 02 Dec 2011 13:30:40 GMT

Hey,

I have installed ESXi5 on an IBM x3550 M3 server. Things appear to be fine, except none of the hardware sensors under the Configuration tab appear to be working. (I.e. I have unplugged one of the power supplies, but both say they are plugged in and everything stays green).

The Configuration tab shows all the right hardware components (I.e. right number of fans, power supplies, memory, ETC.) which makes me think it communicating on some level…but when I do something (like pulling a power plug) everything stays green.

I believe this information is populated form the CIM/SMASH framework. This is a related concern because I am also using a python script with pywbem to retrieve this information for Nagios. I am able to successfully access and read data out of the CIMOM…however the data does not update, making the script useless.

Do I need to install/activate/configure an IBM (some other) CIM Agent??

Thanks!

CIM/SMASH Database on ESXi5 not updating

BurningKrome — Thu, 01 Dec 2011 10:01:25 GMT

Hey,

I’m relatively new to CIM/SMASH…but experienced with scripting and similar concepts (RTAP, PLC, ETC). I’ve written a Python script that reads data out of my ESXi5 server’s SMASH database for hardware monitoring (with Nagios). The script itself works well, except…when I tested the monitoring of hardware changes by (as an example) unplugging one of the power supplies…I could not find any changes in the CIM/SMASH database on the ESXi host.

I checked CIM_PowerSupply::<HealthState, OperationalStatus, Availability> as well anything that referenced the power supplies in the OCM_DiscreteSensor including “Power Supply <X> Power Supply <X> 0: Power Supply AC lost”, and “Power Domain 1 Host Power 0: AC lost”. Everything is indictating the ESX system thinks the power supply is chugging along just fine.

Does the CIM/SMASH database only enumerate on startup? Does something have to be activated/run on the ESX to regularly update the database? I’m really quite at a loss here

Thanks in advance for the help!

Re: ESX 4.1 install crashes at 85% of loading installer

BurningKrome — Mon, 07 Nov 2011 14:09:21 GMT

Thanks Satya. We actually tried it on an identical machine with the same crash. We then tried it on the same basic model with a different motherboard and it installed.

FYI...the crash happens right as the Kernel tries to boot. At the 85% mark, the preinstall file loading is done and the Linux boot takes over. That's what was causing the restart.

Thanks!

ESX 4.1 install crashes at 85% of loading installer

BurningKrome — Mon, 07 Nov 2011 10:05:06 GMT

Hey,

I'm trying to install ESX 4.1 on a Lynx "VBB-TOPSEL-F" Intel i3 system. The ESX install CD boots, gives me the menu to select the installation type (Graphical install, text install)...but no matter which one I select (graphic or text) it loads the installer to 85% and then the systen simply restarts. I've checked the hard drives (Sata) in the bios, turned off everything I can...still no luck.

Help?

Thanks!
