ESXi 4.0 Hardware and Software Monitoring VMWare

[mamema]

try to get this running.
had first problems with installing of the vmware perl sdk, and i'm not dsure if it is running correctly.

Now i do not get any files created in /tmp
both perl scripts in the zabbix folder have a output of "1" if run from the commandline
in the agentd log i have a "No such file or directory"

I guess its the perl script, but i see no error. Is there a higher log level possible?

regards

mamema

Update: got a step further. If i execute the script zabbix_perl_api_vmware.pl from command line with the same serverip/username/pw on the commandline, which is the same as in the script (i edited it) then it works, which is odd, cause the values are the same.
This is not working with the wbem script and not from the zabbix server invoked.....
I also have this in the logs:
sh: /etc/zabbix/zabbix_wbem_vmware.pl: /usr/bin/perl^M: bad interpreter: No such file or directory

and this:

2305:20120820:172126.547 Zabbix agent item [API[{$HOST},{$PASSWORD},{$USERNAME}]] on host [servname] failed: first network error, wait for 15 seconds

CR/LF is the way windows writes end-of-line in text files.
Unix only uses LF, so ou have to change it for the script to work.
A command which works with all distros is:

tr -d '\r' < input.file > output.file
Example
tr -d '\r' < zabbix_wbem_vmware.pl >zabbix_wbem_vmware.pl.new

If the script takes over 30 seconds, you also have to adjust the source code of Zabbix a bit to be able to increase the timeout of the agent.

can you be more specific what you did, please?

After upgrade to zabbix 2.0.2 items API[*] became unsupported.

Under zabbix 1.8.13 all worked fine.

Hi,

i'm lost where must be install wbem ? on esx ? how ?

[ehermouet]

message delete. error from me

[ehermouet]

i think it's because i have don't understand all info.

that i do:

install hp agent on esx server
install vi perl on zabbix server
wbem is on zabbix server and esx server

that's right ?

edit
i have this error message
* /usr/bin/wbemcli: Cim: (3) CIM_ERR_INVALID_NAMESPACE: Invalid namespace

when i do this /usr/bin/wbemcli ei -noverify "https://root:*****@192.168.1.33/root/hpq:SMX_FAN"

agent is installed and i have accès with http interface on esx server


and on zabbix 2 i have -> After upgrade to zabbix 2.0.2 items API[*] became unsupported.
/etc/zabbix/zabbix_perl_api_vmware.pl [IP] [password] [username] work and i have my tmp file (but only work manualy)

tks advance

An other approach

Hi,

First I was using this monitoring for ESX4 machines, but after upgrading to ESX5 it was taking too long. So I rewrote everything and I used credstore_admin.pl for vmware SDK to store the user credential, so you do not need to put these as macro, I prefer not exposing admin password in zabbix UI.

Now my script takes less than 10 s to executes. If somebody is interested I can post my scripts.

My scripts support HP and Dell hardware with auto discovery.

How to store credential for wbemcli?

Could you publish these scripts here?

template + scripts

Here is my little contribution (I am not a perl master, so if you can help me to improve) :

So here are the instructions :

- First you need vSphere SDK installed coorectly. http://pubs.vmware.com/vsphere-50/in...neref.6.1.html

- After you have to store the ESX credentials :
under Ubuntu
$ sudo -i
# /usr/lib/vmware-vcli/apps/general/credstore_admin.pl add -s <ESX_IP> -u <root> -p <password>

the credentials will be stored in /root/.vmware/credstore/vicredentials.xml

- in /etc/sudoers add the following :
zabbix ALL=(root)NOPASSWD:/etc/zabbix/zabbix_esx_get_data.pl *


- In zabbix_agentd.conf add the following :
UserParameter=esx.item.discovery[*],/etc/zabbix/esx.item.discovery $1 $2
UserParameter=esx-get-data[*],sudo /etc/zabbix/zabbix_esx_get_data.pl
--server $1
UserParameter=esx_get_value[*],/etc/zabbix/zabbix_esx_get_value.pl $1 $2 $3

- modify the timeout value = 15 should be enough

- Put all the scripts in /etc/zabbix/ with execution rights without .txt extension

esx.item.discovery : autodiscovery of the hardware
zabbix_esx_get_data.pl : download the data from the ESX and create the data file
zabbix_esx_get_value.pl : retrieve the desired data from the data file

-Now restart zabbix_agent.

- create /var/log/esx-mon directory

- create /etc/logrotate.d/esx-mon with the following content :
/var/log/esx-mon/esx-mon.log {
daily
rotate 7
compress
missingok
notifempty
sharedscripts
create 640 root root
}


- After import the template ESX in your zabbix and create your first ESX server.
hostname : esx_hostname
agent interface : ip of the zabbix server
template : Template_ESX_dellR720
Tab Macro :
macro : {$ESX_IP} value : YOUR.ESX.IP


You can check that the monitoring is working by checking /tmp/<ESX_IP>-esx-data file


Please content and help me to improve.

As I see you exclude perfomance counters.

These counters are time expensive but some of them contains useful information, e.g. network transfer rate.

[geek74]

You have the cpu and memory usage.

And if you need network transfert rate, maybe it is faster to do it via snmp .

[Kryol]

I use modified script to request centrally the ESX hosts via the VCC http://www.zabbix.com/forum/showpost...1&postcount=74.

I tried to invoke this script on zabbix server, VCC and VMA and found that execution times differ.

E.g.
Zabbix ~ 23s
VCC ~11s
VMA ~8,5s

I cannot explain this behaviour.
This is not network features because all of above servers are on same ESXi.

Could somebody try to explain?

[Kryol]

And another question.

I compared execution time for scripts to request data through VCC and directly from ESXi server.

Firsh of them is faster. I think it's very strange.

Am I wrong?

Because in VCC is cached results of status, and VCC polling ESXi by scheduling.
