In this second part of our monitoring Hyper-V article we’ll discuss the details about Processor, Memory, and Storage monitoring. In part 1 we discussed the Overall Health metric set. Let’s start with the Processor Metrics.

Processor Metrics

There are three processor-related metric sets:

Scheduling Custom Monitors with Monitis and PowerShell

In last article, we talked about creating custom monitor updater commands that would run a script and upload the values to Monitis.  These custom updaters make it a snap to convert any PowerShell script to a Monitis monitor.  Simply plug the script in and start using it’s more logical name: Update-YourMonitor.

As we have discussed on the Monitis blog virtualization is one of the hottest IT subjects today.

One leader in this field is Citrix — with the XenServer product family. XenServer is the most known commercial implementation of of the open source Xen hypervisor. By the way, you should pronounced Xen like “zen.” It comes from a Greek word meaning “guest.”

Need for Speed?

With its first public release in 2004, NGINX now is the second most used web server in the world. This is quite impressive considering NGINX was born among several big players including Apache, Microsoft IIS, and other popular web server software. By sharing best practices and a few tips today, we would like to bring NGINX’s new blood up to speed. Even if you come from the Apache world, you will learn how to build an Apache server that married NGINX, an extremely fast and high-performance web server. Let’s go:

In this article we’ll go into VDI (virtual desktop interface) monitoring on Windows Server Hyper-V and in particular what and where to monitor and what counters to utilize to determine of your virtual machine is overloaded and what resources are used. This article focuses on measuring networking, storage, and CPU usage.

Windows Hyper-V has three main components, each of which can be monitored; the virtstack, devices, and the hypervisor. When Windows 2008 boots the system it launches the virtstack and hypervisor. The virtstack handles the emulated devices, manages virtual machines, services I/O, etc. The Hypervisor schedules the virtual processors, manages interrupts, services timers, and controls other chip-level functions.

Pluggable M3 (Monitis Monitor Manager) Framework

Who needs an introduction about M3? – Perhaps no one!
After gaining some reputation with M3, providing extra-easy integration of any monitor into Monitis it was time to take it to the next level.

Generally speaking, the work flow of M3 was described in detail in this article.

After some thought and design, we’ve decided it’d be best if M3 was pluggable. Pluggable in terms of being able to easily add execution and parsing plugins.
The interface and behavior of M3 stayed exactly the same, however now it is much easier to obtain data from any source and parse the data the way you want it.
Saying that, it was time to put the new design for a test. We tried to integrate the DBI support into M3.
Guess what – it was much easier than expected!

Cassandra is a robust and highly scalable NoSQL datastore that usually consists of multiple nodes spread out across multiple datacenters.  If you are the system administrator for a large Cassandra deployment then you might be curious as to how your cluster is doing.  In fact your job probably depends on it!  So how can you combine a great service like Monitis with Cassandra to make sure you cluster is buzzing along smoothly?

The Internet is a great resource, but it is sometimes too much to wade through hundreds of web pages looking for tips about using Tomcat with a database. So we at Monitis have done it for you! Below are some of the more useful tips found in various places on the Internet.
