ESXi 4.0 Hardware and Software Monitoring VMWare

[dima_dm]

how can i monitor esxi 4.1 via snmp?

can somebody give me a step-by-step-guide?

No. Only WBEM and VMWare API

@dima_dm: where must i install the perl-api?!

On Zabbix Server

[dima_dm]

I'm trying to run zabbix_perl_api_vmware.pl against vcenter, and am getting:

I don't test this script with vcenter, only with ESX/ESXi host.

[753713]

we can I integrate this Nagios-Script on zabbix?

http://exchange.nagios.org/directory/Plugins/Operating-Systems/%2A-Virtual-Environments/VMWare/Vmware-ESX-%26-VM-host/details

can anyone help?

[Colttt]

ok,

i install the vsphere toolkit on debian squeeze, i copy the zabbix_perl_api_vmware.pl into /etc/zabbix/externalscripts and change IP, User and password, now when i start this script i become an 1

/etc/zabbix/externalscripts/zabbix_perl_api_vmware.pl
1

1= error with perl API
buw how can i fix this?

and in zabbix i become "not supported"

[dima_dm]

Try run
/usr/lib/vmware-viperl/apps/performance/viperformance.pl --host HOST_NAME --server HOST_IP --countertype net --samples 1 --instance "*" --username root --password PASSWORD
Is it works?

[Colttt]

yes it works..
and when i use:

/etc/zabbix/externalscripts/zabbix_perl_api_vmware.pl IP-ESX password user
0

it works..

but i dont have any value in zabbix..

here is an error:

24258:20110519:122831.033 Expression [{12998}#0] for item [26874][csfvirt1:API[{$HOST},{$PASSWORD},{$US

[dima_dm]

Do you set Timeout for Zabbix Server and Zabbix Agentd?
/etc/zabbix/zabbix_server.conf
…
Timeout=30
….

/etc/zabbix/zabbix_agentd.conf
Timeout=30

[Colttt]

ok.. now it works.. i used macros global and not only for the host.. i change the macros in the hostmacros..

now i´ve values.. but it don´t refresh the values..
it looks like he dont start the zabbix_perl_api_vmware.pl.. when i run it manually i get new values..

ls -la /etc/zabbix/externalscripts/zabbix_perl_api_vmware.pl

WBEM problems

Hi all,

great work that scripts dima_dm!

I've got a problem with the wbem script. It exits with 5.

the check with wbemcli returns a long string so it might be ok:
/usr/bin/wbemcli ei -noverify "https://user:********@myserveripaddress/user/hpq:SMX_FAN"
myserveripaddress:5989/user/hpq.....
...CurrentSpeedState=

but the script:

/etc/zabbix/zabbix_wbem_vmware.pl myserveripaddress ******** user

returns that 5.


Do you have any idea of what colud be happening?

Thx a lot!

PD: HP agents are installed but it's not a DL360 G6 but a Blade 460c G6. ¿Can this be the problem? ¿Is your script usefull only aganist that HP model?

Hello everybody, I have read all post of this topic but I've still a few questions :

1. For the procedure you explain, is it working for ESX4i Update 1 ?
2. I recently have migration from ESX3.5 to ESX4i Update 1. When I was to ESX3.5, I had just install the zabbix agent. Then, I had created a script that send some values (Datastores spaces mostly) to a zabbix trapper. Since I have upgrated to ESX4i, I'm not able to install the zabbix agent as I did for ESX3.5. My last error when I tried to "./configure --enable-agent" is

"Configure: error: in '/root/zabbix-1.8.5'
"Configure: error: no acceptable C compiler found in $PATH

Actually, I'm not able to install a GCC Compiler because RPM, YUM commands don't exist.

So, does anybody know if we could install zabbix agent on that kind of ESXi ?

Thanks you for your reply.

Your macros don't work.You must check macros configuration in Zabbix.

[dima_dm]

but the script:

Do you see hardware status for all hardware in VMWare client (Configuration->Health Status)?
If no, there are problems with HP agents on ESXi hypervisor, you can restart ESXi hypervisor to fix problem.
This bug exists in VMware 4.0, and was fixed in VMware 4.1

PD: HP agents are installed but it's not a DL360 G6 but a Blade 460c G6. ¿Can this be the problem? ¿Is your script usefull only aganist that HP model?

No, you can use any HP model of server if you have HP agents on ESX/ESXi Hypervisor compatible with this model of hardware.

ESXi don't have Service Console.
See:

http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1023990

You can't install zabbix agent on ESX4i hypervisor. You must use VMWare API and WBEM for monitoring ESX4i hypervisor.

WBEM problems

Hi dima_dm,

directly connected to the ESXi host (an ESXi 4.1 U1 + HP agents) i can see some sensors but less that I can see through the vCenter console (this host is part of a vSphere cluster). There were less sensors detected before installing HP ESXi Offline Bundle (hp-esxi4.1uX-bundle-1.0a.zip). I have also rebooted the host but no change on zabbix_wbem_vmware.pl. Still getting a 5. I coult eventually exclude this host from the vCenter to try out the script. I'll also look at the script more in deep to see if it is getting something not expected. I already told that the plain wbem client was getting some results.

Thanks for all dima_dm,

Txa.

WBEM problems

Hi dima,

I've located the problem. SMX_PowerSupplyModule wasn't returning any value so the $count var was reset to 0. Thus the eval count==0 is true and returns a 5. I've deleted SMX_PowerSupplyModule from the list of keys (commented it out) and now it's generating the temporary text file but with very few values:

Temperature_8: 67
Temperature_7: 49
SMX_NumericSensor_6: 2
SMX_NumericSensor_9: 2
SMX_NumericSensor_4: 2
Temperature_5: 42
Array_0: 2
Virtual_Fan_at_Platform_backplane_in_Blade=2: 2
Temperature_4: 34
System_Memory: 2
Temperature_6: 46
SMX_NumericSensor_3: 2
Temperature_1: 40
Temperature_2: 40
SMX_NumericSensor_1: 2
Temperature_9: 21
SMX_NumericSensor_0: 2
SMX_NumericSensor_2: 2
Proc_1: 2
SMX_NumericSensor_5: 2
SMX_NumericSensor_8: 2
SMX_NumericSensor_7: 2
Temperature_0: 23
Temperature_3: 38
Proc_2: 2

thats all... This must be due to a change in VmWare hipervisor, like always.

Thanks for all,

Txa.
