Improved VMWare Monitoring with VmBix

[Jason]

Thank you for this. So the key in zabbix for active is vmbix[esx.counter,{HOST.HOST},mem.active.average] ?

[tatapoum]

Correct. And you need to set the Zabbix polling interval to 300s to get accurate results.

[Jason]

The CPU usage item is wrong. It's

(last("vmbix[esx.cpu.load,{HOST.HOST},used]")/last("vmbix[esx.cpu.load,{HOST.HOST},all]"))*100

and I think it should be

(last("vmbix[esx.cpu.load,{HOST.HOST},used]")/last("esx.cpu.load[{HOST.HOST},all]"))*100

[tatapoum]

You're right. I'll fix this in the next release.

[Jason]

It might also be a good idea to add some utilisation triggers... For example I'm putting ones that show when CPU utilisation on the host is over 75% and for low space on storage devices etc?

[Jason]

Might also be worth suggesting in the documentation that a read-only user can be used for monitoring.

High bandwidth usage on Zabbix VmBix server

Hi people,

in my setup I have vCenter 6 with 2 virtualization hosts and about 320 virtual machines managed by vCenter.

Also, I have the Zabbix 3.0.4 with VmBix 2.4 installed on CentOS 7 x64.

With default setting of VmBix (after VMs discovery has done), inbound network traffic is about 50 Mbps average. Almost all traffic if coming from vCenter. During monitoring used tools nload, nethogs and iftop.

Is there a way to determine which items are top consumers of bandwidth? How I can optimize bandwidth usage on Zabbix server?

For now, I disabled following items on Template VmBix VM Loadable Module:
Ballooned memory, Compressed memory, CPU Freq, CPU Overall Usage, CPU Ready, CPU Ready (%), CPU Total, CPU Used, Memory Latency, Private memory, Shared memory, Swapped memory, VM Tools mounted, VM Tools running, VM Tools status.

Also, increased Update interval on several items and Discovery rules.

Is there a way to determine which items are top consumers of bandwidth? How I can optimize network bandwidth usage on the Zabbix server with VmBix?

Please help

Hi,

Greate job, thank you for this usefull tool!

Unfortunately i have a small issue with VM Tool status.
Thats what i see in vmbix log:

Do someone have an idea where i have to look for solution?

Thanks!

Hi,

This is a great add on!!!

I do have one question though. I have added my vcenter and its discovered all of the vms, datastores etc etc however they are all read only and I would like to attach windows templates to most of the VMs. Reading through your documentation you list this as a benefit over the standard vm monitoring however i cannot figure out how it works. Can you please enlighten me


Cheers

[Jason]

Ummm attach windows templates to the virtuals? You're just reading the API's from VMware. This has no access to the OS of the virtual itself.

[stav13]

Hmmm I'm confused the. As on the GitHub page it says

The created ESX and VM hosts are mostly read-only. You cannot attach them different templates, put them into different groups, or use a Zabbix agent to monitor their OS or apps

So I would assume that Vmbix overcomes this?

Thats what you are looking for: vmbix-object-sync script

Anyway it's gives you only the possibility to edit the host (Adding agent/snmp/simple check etc). For Agent monitoring you will still need to install the agent

Hi! i just installed VmBix and i have an issue, hope you guys can help me with, when i run:

[root@redmine addons]# zabbix_get -s 127.0.0.1 -p 12050 -k vm.consolidation[SBG_mail,needed]

The result is:
1

So it works! But when i link this host (SBG_mail) to the Template VmBix VM Loadable Module, the result in the "Consolidation needed" item is "Unsupported item key" and in the vmbix log says " 2357:20160908:150156.659 item "SBG_mail:vmbix[vm.consolidation,{HOST.HOST},needed]" became not supported: Unsupported item key."

Can you guys help me? Thanks!
