Hewlett-Packard introduced a new component called HP Agentless Management within their Gen8 Series. This feature is extensible though an agent running inside the operating system, in that case the ESXi Host. The package (hp-ams) is included in all customized VMware images provided by HP and the HP ESXi Offline Bundles. Unfortunately this package create some issues caused by excessive local logins. This might pointlessly blow up the database and logfiles. You can check that problem by opening the Event-Log provided by the ESXi Host which is flooded with the following messages:
User root@127.0.0.1 logged in as User root@ logged out (login time: , number of API invocations: , user agent: ) User root@127.0.0.1 logged in as User root@ logged out (login time: , number of API invocations: , user agent: )
In this post i am going to show how to workaround this issue and remove the hp-ams from you ESXi Host, and how to build a new image without that package.

Hewlett-Packard has just released a Generation 8 Microserver which is going to replace the well-known N36L/N40L/N54L Microservers. The new server has the same trendy design as the entire Gen8 series. The AMD Turion CPU has been replaced by an Intel Ivy Bride CPU which is way more powerful and the memory limit has been raised to 16GB. With that, the new server brings much more power to your VMware vSphere Homelab and allows you to run more virtual machines. In this post, I am going to compare both specs to point out what's new and better.
Running commands inside a virtual machine without accessing it can be helpful in some cases. For example when you want to change an IP address from a Linux virtual machine that is not reachable through ssh. VMware provides the VIX (Virtual Infrastructure eXtension) API that helps you to write scripts to automate virtual machine operations and run programs within guest operating systems. I am going to show some basic VIX implementations using PowerCLI.

VMware has just release a new log aggregator called vCenter Log Insight. It's a new tool that collects and aggregate logs from vCenter Server and ESXi Hosts. vCenter Log Insight is delivered as virtual appliances and can be deployed in less than 10 minutes. If you know Splunk you might be familiar with the user appearance. In my opinion a tool like vCenter Log Insight is indispensable for troubleshooting purposes.
With the separation of the vCenter Service into 4 components in vSphere 5.1 (vCenter Single Sign On, vCenter Inventory Service, vCenter Server and vSphere Web Client) there is a possible issue that you could have mismatched services installed. When you install an update you have to install all components one after another without having a workflow to check that all have been updated. I have already written about the update process from 5.1 to 5.1u1 and their versions but this is not the only update available. Now I've created an overview of all possible vCenter 5.1 version numbers that can be identified in the Control Panel.
