Re: wrong cpu cores number (G850)

Hi alibek,
as you're showing us, agent seems to rightly inventory the corecount: <CORECOUNT>2</CORECOUNT>
Do you mean you don't see 2 cores in GLPI ? Can you make a screenshot of what is wrong if that's the case ?

Hi gbougard,
Yeah i don't see 2 cores in GLPI.

Re: wrong cpu cores number (G850)

Today i analized output of fusioninventory-inventory.bat on some other computers with different processors there is no <CORECOUNT> parameter. Only <CORE> and <THREAD>. So i suppose problem with fusioninventory not with glpi.

Re: wrong cpu cores number (G850)

just find specification for inventory protocol:
htt p hmm /fusioninventory.org/documentation/dev/spec/protocol/inventory.html
there is no <CORECOUNT>
only:
<!-- cores number -->
<!ELEMENT CORE (#PCDATA)>
<!-- threads per core number -->
<!ELEMENT THREAD (#PCDATA)>
so GLPI takes <CORE>1</CORE> for core numbers
and <THREAD>1</THREAD> for threads numbers per core.
Where exactly fusioninventory take this numbers?  Is it possible somehow to fix this problem?

Re: wrong cpu cores number (G850)

It seems on this computers manufacturer set wrong information in dmi table. Is it ok if i replace string
CORE => $info->{'Core Enabled'} || $info->{'Core Count'}
with
CORE => $info->{'Core Count'}
in getCpusFromDmidecode Generic.pm file?

Re: wrong cpu cores number (G850)

Hi alibek,

in fact we add CORECOUNT only if different than CORE. This is the case for you 'cause of your dmidecode output:
        Core Count: 2
        Core Enabled: 1

Are you sure all the 2 cores are enabled ? Also you said "It seems on this computers manufacturer set wrong information in dmi table.", have you any reference from the manufacturer telling about that ?
Any way, this is finally not an agent issue:
1. Or you have a core disabled for any reason, if this is the case you should investigate in that way,
2. Or the SMBIOS informations read by dmidecode are wrong and you should than ask your manufacturer for a fixed BIOS/Firmware.

If you change the code as you wish, you'll just hide the real problem. And next agent upgrade will reset your change.

About CORECOUNT missing in spec, I jus fix that in the doc. Thank you for the trigger.
