Monitoring ESX datastore

[jay]

Hi,

Here is a small script to monitor ESX datastore. It is very simple so be free to improve it :

ZABBIX_SERVER="zabbixhostname";
ZABBIX_PORT="zabbixport";

ZABBIX_SENDER="/pathtozabbixsender";
KEY=$1;
HOST="ESXhostname"
TOTAL=100
VALUE=""

VALUE=`/usr/sbin/vdf -h | grep /vmfs/volumes/$1 | awk '{print $4}' | sed 's/%//g'`

if [[ $VALUE = [0-9][0-9] ]] || [[ $VALUE = [0-9] ]]; then
VALUE=$(( $TOTAL -$VALUE ))
$ZABBIX_SENDER -z $ZABBIX_SERVER -p $ZABBIX_PORT -s $HOST -k $KEY -o $VALUE
else
$ZABBIX_SENDER -z $ZABBIX_SERVER -p $ZABBIX_PORT -s $HOST -k $KEY -o "0"
fi

Hi,

Thanks for the script, i'm a beginner in zabbix monitoring and i'm french So please excuse me if i make mistakes.

I would want to know how you use this script?
What is the language ? is it just algo ?

I'm searching the best way to monitoring my ESX 4:
- Zabbix agent
- snmp (with Vsphere?)

?

Thanks you.

It's a little bit difficult to have all configured, but I use and recommend the usage of the scripts presented on this post:

http://www.zabbix.com/forum/showthread.php?t=15691

My hardware is not HP and I could easily adapt the scripts in order to get them working.

Ok But how do you use these scripts?

I've Dells

- Did you install zabbix agent on the esx (I have the impression that is what dima_dm did?? )

Excuse me, I find it not easy to understand all the procedure because of my tongue

Thanks for your help

Although the scripts were made for ESX machines, I successfully use them to monitor ESXi (freeware version of VMware ESX) servers.

To use the scripts, you first have to elect a machine that will collect the ESX data. One option is to use zabbix server. As those scripts use to degread a little bit the server performance, I've decided to use another machine to collect the ESX data and send them to zabbix server.

On this elected machine I've installed "VMware Infrastructure (VI) Perl Toolkit" and "WBEM wbemcli" as required on the post http://www.zabbix.com/forum/showthread.php?t=15691. Then I've configured cron to run "/etc/zabbix/zabbix_wbem_vmware.pl" and "/etc/zabbix/zabbix_perl_api_vmware.pl" regularly and send the output to zabbix server. On the zabbix server I've created a script that reads this output.

[benito103e]

Very Interesting

Is there a software required in ESX (to add ?) ?

On the zabbix server I've created a script that reads this output.

does Your script use the zabbix_sender??

I think I will use Zabbix_server to collect ESX data, and change a little bit the script to send directly information to zabbix and not write it on a file (perhaps the two things at the same time)
--> zabbix server will launch the script : deleting cron

Thanks !

[Murilex]

No, it's not necessary to install any software in ESX. I don't use zabbix_sender presently, but this is for sure a good alternative.

[benito103e]

Ok,

So what do you use to get data in Zabbix ?

I will read the manuel to how use script, and get back information in zabbix server !

Thank you very much !

[Murilex]

Hello benito103e. As I said, I use a simple script on zabbix server that read data from a plain file. This plain file is generated on a helper machine (that I elected) and moved to zabbix server from times to times (by using scp!).

[benito103e]

Hi Murilex,

Thanks for all your precision, It lights me

I'll choose my way to get data, with your advice.

Hi buddy, were you able to set this up for production already? How is it?

We have created a Windows powershell script:

@"
===============================================================================
Title: 			Report-Datastores.ps1
Description: 	Report Datastore usage for all Datastores managed by vCenter
Requirements: 	Windows Powershell and the VI Toolkit
Usage:			.\Report-Datastores.ps1

#ADD VMWARE PSSNAPIN 
Add-PSSnapin -Name “VMware.VimAutomation.Core”
#FORCE TO LOAD VMWARE POWERSHELL PLUGIN

#Global Functions
#This function generates a nice HTML output that uses CSS for style formatting.
function Generate-Report {

 
				Foreach ($store in $report){
					
					echo $($store.name)
					cmd.exe /c "C:\Zabbix\zabbix_sender.exe -z <zabbixip> -s $($store.name) -k data.store.total.space -o $($store.CapacityMB)" 
					cmd.exe /c "C:\Zabbix\zabbix_sender.exe -z <zabbixip> -s $($store.name) -k data.store.free.space -o $($store.FreeMB)" 
					cmd.exe /c "C:\Zabbix\zabbix_sender.exe -z <zabbixip> -s $($store.name) -k data.store.free.percent -o $($store.PercFRee)" 

				}

	}

#Login details
$username = '<username>'
$password = '<password>'

#Current, Previous, Difference File information
$digits = 2
$Folder = 'C:\Reports'

#List of servers including Virtual Center Server.  The account this script will run as will need at least Read-Only access to Virtual Center
$VIServer = "<vcenter server"	

#Initialise Array
$Report = @()

# Connect to Virtual Center
$VC = Connect-VIServer $VIServer -user $username -password $password

# Get all datastores and put them in alphabetical order
#$datastores = Get-Datastore | Sort-Object Name

#Get all datastores and put them in alphabetical order
		foreach ($server in $serverlist){
		
		# Check is server is a Virtual Center Server and connect with current user
		if ($server -eq "VCServer"){Connect-VIServer $VIServer}
		
		# Use specific login details for the rest of servers in $serverlist
		else {Connect-VIServer $VIServer -user $username -password $password}
		
		
		Get-Datastore | Sort-Object Name | %{
			$Store = {} | Select Name, CapacityMB, FreeMB, PercFree
			$Store.Name = $_.name
			$Store.CapacityMB = [math]::Round(($_.capacityMB*1024)*1024,0)
			$Store.FreeMB = [math]::Round(($_.FreeSpaceMB*1024)*1024,0)
			$Store.PercFree = [math]::Round(100*$_.FreeSpaceMB/$_.CapacityMB,$digits)
			$Report += $Store
								}
		# Disconnect from Virtual Center
		Disconnect-VIServer -Confirm:$False
		}
										
# Disconnect from Virtual Center
Disconnect-VIServer -Confirm:$False

# Generate the report and email it as a HTML body of an email
Generate-Report

You only have to change:
<zabbixip> = IP of the zabbix server
<username> = Username for vCenter
<password> = Password for vCenter

We run the script on a Windows server with the vSphere client and commandline tools installed.

With schedule tasks we run the script every 30 minutes.
It generates a trigger when datastore is almost full.


Hopefully somebody can use the script.

Hi,

I've tried this script but run into this error message:
ESXVOL1
the system can not find the file specified
the system can not find the file specified
the system can not find the file specified
ESXVOL2
the system can not find the file specified
the system can not find the file specified
the system can not find the file specified

etc.

Maybe you can help?

p.s. sorry for my engelish
