Hello cynfewl,

sorry, your answer is not very helpful, because the Zenpack works, except the CPU-drawing.

When I try to install the SNMP-Modules, the following Message occurs:

cpan> install SNMP
SNMP is up to date.

cpan> install NetSNMP
Warning: Cannot install NetSNMP, don't know what it is.
Try the command

    i /NetSNMP/

to find objects with matching identifiers.

Is it right, that the SNMP-Modules are installed?

Regards dbuck

Hello cynfewl,

thank you for assist and bring me in the right direction. I installed the module NET::SNMP and now the above described error message wouldn't be shown again. Now on the command-line as user zenoss the command:

/home/zenoss/ZenPacks/ZenPacks.vmware.VirtualMachines-1.2-py2.4.egg/ZenPacks/vmware/VirtualMachines/libexec/check_esx2 -N -H fqdn.host.name -C snmpcommunity -v Zenoss-Appliance -l CPU -w 90 -c 95 |sed -e 's/.*CPU\susage\sis\s/cpuUtil=/;s#%##;s/on.*(/cpuSec=/;s#s##;s/average.*$$//'

displays:

cpuUtil=16.98 cpuSec=106 average)

So I delete one of the two "$$" at the end of the command.

Now it displays:

cpuUtil=15.9 cpuSec=132

I correct it in the Template, but it shows no Graph. Is this the right output-format for the datapoint?

Regards dbuck

Ok, I think I have this going.

dbuck, I noticed the same thing as you about the double $$, but I got errors running the command through Zenoss with a single $.

I've had a look at the code in the check_esx2 perl script, and it seemed like since this was only doing an SNMP poll, it should be possible to pull CPU usage without an external command.

I've created a new datapoint, and have some screenshots, but I don't know how to make this a zenpack or post pictures.

Basically, to get CPU monitoring going, do the following:

1. Delete the existing CPU_Utilization Data Source.
2. Create a new CPU_Utilization Data Source of type Derive that polls the OID 1.3.6.1.4.1.6876.3.1.2.1.3 with RRD Min value of 0.
3. Add the Data Source to the graph CPU_Utilization.
4. Delete the existing missing Graph Point with sequence number 0.
5. Change the units to Percent, the Min Y to 0 and Max Y to 100.
6. Click the remaining Graph Point and change the name to Utilization_cpuUtil, RPN to "100,*" (without quotes), format to %5.1lf%% and legend to Utilization.

Delete any existing RRD graphs for the virtual hosts called CPU_Utilization_CPU_Utilization.rrd (I do this from the command line with a find).

In about 15 minutes, you should have CPU usage for the individual virtuals.

I'm not sure if this is 100%, but it appears to work for me...

cynfewl.

I managed to make the VirtualMachines zenpack running.
1) install the zenpack and restart zopectl
2) Before you add a server to the class /Devices/Server/ESX you have to go to the zProperties of that class en fill in at the zPythonClass this rule of text

/usr/local/zenoss/zenoss/ZenPacks/ZenPacks.vmware.VirtualMachines-1.2-py2.4.egg/ZenPacks/vmware/VirtualMachines/libexec/check_esx2

This add's the Virtual machines tab to every new device you add to /Devices/Server/ESX
I found this on http://forums.zenoss.com/viewtopic.php?p=29512

If you already have a device in the class ESX you have to move it to another class and move it back to the ESX class.
3) add a esx server to /Devices/Server/ESX
4) Now you see the tab Virtual machines.

To make the CPU_Utilization graph work you have to make a change in the template.

1) Navigate to you esx server and go to Virtual Machines. Click on a virutal machine.

2) Click on the tab templates

3) Click on the VirtualMachine template

4) Click on the Data source CPU_Utilization

5) Check if the path for the check_esx2 command is set correctly, test it thru your terminal

I get when I put this in a terminal

No ESX server hostname specified with -H

you have to get this

DEBUG:zen.zencommand:The result of "/usr/local/zenoss/common/libexec/check_ping -H esx-cr01.iconos.be -w 180,100% -c 300,100% | sed -e 's# - Packet loss#|LOSS#;s#%,##;s#ms##;s# = #=#g'" was "'PING OK|LOSS=28 RTA=1.03 |rta=1.031000ms;180.000000;300.000000;0.000000 pl=28%;100;100;0\n'"
DEBUG:zen.zencommand:Queueing event {'severity': 0, 'performanceData': 'LOSS=28 RTA=1.03 |rta=1.031000ms;180.000000;300.000000;0.000000 pl=28%;100;100;0', 'component': '', 'agent': 'zencommand', 'summary': 'PING OK', 'manager': 'localhost', 'eventKey': 'ipcheck', 'device': 'esx-cr01.iconos.be', 'message': 'PING OK', 'eventClass': '/Status/Ping'}

This means the path is set correct.
Now the fault is in the sed command. I think that the result of the check_esx2 command wasn't correctly parsed. I found this thru the command zencommand run --device=devicename.domain.local -v10
I saw that the check_ping command has parsed the output to

/usr/local/zenoss/zenoss/ZenPacks/ZenPacks.vmware.VirtualMachines-1.2-py2.4.egg/ZenPacks/vmware/VirtualMachines/libexec/check_esx2 -N -H ${dev/id} -C ${here/zSnmpCommunity} -v  ${here/vmDisplayName} -l  CPU -w 90 -c 95 |sed -e 's/.*CPU\susage\sis\s/cpuUtil=/;s#%##;s/on.*(/cpuSec=/;s#s##;s/average.*$$//'

You see that the result is devided in vertical bars. But with the esx_check2 is wasn't. So...

6) on the Datasource CPU_utilization you edit the command from

/usr/local/zenoss/zenoss/ZenPacks/ZenPacks.vmware.VirtualMachines-1.2-py2.4.egg/ZenPacks/vmware/VirtualMachines/libexec/check_esx2 -N -H ${dev/id} -C ${here/zSnmpCommunity} -v  ${here/vmDisplayName} -l  CPU -w 90 -c 95 |sed -e 's/.*CPU\susage\sis\s/|cpuUtil=/;s#%##;s/on.*(/cpuSec=/;s#s##;s/average.*//'

TO

/usr/local/zenoss/zenoss/ZenPacks/ZenPacks.vmware.VirtualMachines-1.2-py2.4.egg/ZenPacks/vmware/VirtualMachines/libexec/check_esx2 -N -H esx-server.local.be -C public -v virutalMachineName.local.be -l  CPU -w 90 -c 95 |sed -e 's/.*CPU\susage\sis\s/|cpuUtil=/;s#%##;s/on.*(/cpuSec=/;s#s##;s/average.*//'

So delete the two $$ on the end and add a vertical bar | before cpuUtil

Now the command should be parsed correctly.
You can test this in you terminal. It is not possible to test the command via the webgui. Because ${here/vmDisplayName} isn't there. Just replace the TALES expressions
eg:

|cpuUtil=5.88 cpuSec=68

and if you get something like this

ZenPacks.vmware.VirtualMachines.VMDevice

Than it works :lol:

I have Zenoss Core 2.4.1 on a Ubunut 8.04.2 and installed the ZenPack: ZenPacks.vmware.VirtualMachines-1.2-py2.4.egg

Sorry for my bad English. If you have a question I'm glad to help you.
