Monitoring VMware with Monitis

Turn your datacenter into a flexible cloud infrastructure

Turn your datacenter into a flexible cloud infrastructure with the performance and reliability needed to run enterprise applications on the platform trusted by the most demanding datacenters around the world. Leverage existing assets and applications while offering self-service deployment and provisioning through virtualization. Create a private cloud and deliver IT infrastructure as an easily accessible service.

Deliver IT as a service, when and where needed, while reducing capital and operating costs. Reduce power needs while freeing your IT staff from mundane administrative tasks so they can focus on innovative solutions to your changing business needs./p> Monitoring VMware

When monitoring NetFlow on Vmware, one of the major challenges is to identify which virtual machine or host is using which network resource or bandwidth. Best practices say to use VMware Host to get all the network performance data. Before you launch the PowerShell script you must install Vmware PowerCLI and the startup shortcut on the menu under Vmware, Vmware vSphere PowerCLI. When you start PowerShell from that shortcut, PowerShell automatically runs a configuration script that load the PowerCLI snap-in.

Here is a link to download Vmware vSphere PowerCLI last Version 5.0.
http://communities.vmware.com/community/vmtn/server/vsphere/automationtools/powercli

If you’re not using the shortcut (PowerCLI from vmware), you can load the PowerCLI snap-in directly at a PowerShell prompt, user this name with Powershell add PSSnapin cmdlet, like this:

Add-PSSnapin Vmware.VimAutomation.Core

Once you manage to get a local system command prompt, launch PowerShell and navigate to your script directory. Then run the two scripts, so type in the user name and password you want to use against Host, and you’re ready to start running Vmware scripts securely like this example:

Network.ps1 “Get Host Network info”

NetworkFinish.ps1 “Get Host Net-flow”
Example:


Prerequisites:

The following will need to be installed for you to run the script:

  • PowerShell V2

When talking IoT we often focus on the devices, the sensors, the hardware itself. The new smart appliances, the new smart or self-driving cars (which are amalgamations of many ‘things'). When we are looking at the world of IoT, we should take a step back, look at the big picture. What value are these devices providing. IoT is not about the devices, its about the data consumed and generated. The devices are tools, mechanisms, conduits. This paper discusses the considerations when dealing with the...
