Monitoring VMware vCenter Appliance with SNMP

VMware provides a vCenter (Linux) Appliance since vSphere 5. Unfortunately, the one shipping with 5.0 was a bit low on features. I am giving a try on v5.1 and it is far better. Except that SNMP in not enabled…

I’ll keep the quick&dirty directions here. The source link is already quite complete.

Monitor VMware vSphere from OpenBSD using the Perl SDK

Last time, I had a look at how to monitor VMware vSphere from FreeBSD using the Perl SDK. Quite simple using the ports!

Believe it or not, installing and running the VMware vSphere Perl SDK on OpenBSD is as simple as breathing. Here’s the POC.

Quick tour of the Veeam ONE 6 for VMware and Hyper-V

Part of my daily job is checking clients infrastructure health. Most of them have VMware vSphere, some have Hyper-V. I use a home-developed set of tools to gather, compute and report performance and health data and metrics. Quoting Veeam ONE for VMware and Hyper-V homepage: “(…) Veeam ONE is a single solution for powerful and easy-to-use monitoring and reporting for VMware and Hyper-V. It provides complete visibility of the virtual infrastructure and affordably delivers the capabilities that matter most to virtualization administrators”. Read the official homepage for more information.

Here I’m going to have a quick look at what Veeam ONE 6 does, how and if it’s worth it.

Choosing between AMD and Intel for the Virtual Infrastructure

My ESXi v5 runs on a Mini-ITX Z68 motherboard with Intel Core i5 2500T (Quad core). I choose this because I wanted to have a silent (fanless) and low consumption box. The box runs quite well. The only thing that I regret is that I don’t have access to any sensors from the vSphere client. I was looking at the SuperMicro motherboards as they seem to provide IPMI.

The SuperMicro H8SCM-F looked really really nice. Micro ATX Form, integrated IPMI and KVM, support for up to 128GB of RAM and AMD Opteron 4000 Series ; the Opteron 4256 EE @2.5 GHz have 8 cores and a TDP of 35W! So I started to wonder how whould an Opteron 4256 EE (8 cores, 2,5GHz, 35W TDP) performs vs my Core i5 2500T (4 cores, 2,3GHz, 45W TDP). According to SPECfp2006 Rate Results, the AMD Opteron 4256 EE would have a baseline of 67 and the Intel Core i5-2500T would have a baseline of 87. A better comparison should be done with Opteron 3250 HE (4 cores, 2,5GHz, 45W TDP) which is ranked 52.

Then the big question raised: is it better to choose AMD or Intel for the virtual infrastructure. I recall reading than AMD processor were perfect for virtualization because they have more cores and use less power. But this was the marketing chat and was published a year ago. What I’m going to do here is try to understand how to compare processor in the case of hypervisor.
