Capacity Planning – OMS Vs. OpsLogix Capacity Reports MP

Written by Tao Yang

Introduction

When it comes to data center / fabric capacity planning, currently there are 2 major solutions within Microsoft’s System Center and OMS space. These solutions are:

In this post, I will discuss the differences and similarities between these 2 solutions

OMS Capacity Planning Solution Overview

The OMS Capacity Planning solution was designed to provide an overview on the current and future utilisation of your virtualisation infrastructure and fabric. It is freely available for all OMS customers (well, you do have to pay for the OMS data consumption).

It collects a set of performance data via OpsMgr, and forecast your resource utilization based on the performance data collected.

If you have not used the OMS Capacity Planning solution yet and would like to learn more, here is a list of great resources for you:

To date, out of all the solutions that OMS provides, the Capacity Planning Solution is probably the one that has the most complex requirements. It requires:

  1. Hyper-V hosts managed by VMM
  2. VMM fully integrated with OpsMgr (configured via VMM console)
  3. OpsMgr connected to OMS Workspace
  4. VMM Management Servers and Hyper-V hosts onboarded to OMS via OpsMgr

Because of the nature of this solution, it collects a specific set of performance counters on VMM and Hyper-V servers to forecast the compute and storage fabric within your virtualisation infrastructure. It does not work for Other types of hypervisors that are being managed by VMM (i.e. VMware).

It provides some charts and diagrams which gives you a high level overview of your fabric.

You can also access the performance data collected by this solution via Search (Type=Perf)

OpsLogix Capacity Report MP Overview

Unlike OMS Capacity Planning solution, the OpsLogix Capacity Report MP is not a hybrid solution. It does not require integrations with any products. Once you have imported the Capacity Report MP and the license MP, you should soon see the number of reports deployed in your OpsMgr management group.

As the names suggest, with the two absolute value reports, you can pick any performance collection rules for the language that you have selected (default to “English”).

and the report lists each instance you have selected.

The 2 columns on the left shows the forecasted changes and the forecasted value for each instance based on the time frame you have selected.

The percentage value reports are designed for the performance collection rules that are collecting percentage values. You can also specify warning and critical thresholds (in number of days) for the forecasted data.

Or, if you only want to see the critical ones, you can use “Critical Only” reports.

Comparison

Although both solutions provide forecasting capabilities for your infrastructure managed by OpsMgr, it serves different purposes.

OMS Capacity Planning solution collects a specific set of performance counters around the compute and storage fabric, and provides a high level view on what is the current and future capacity for the fabric in your Hyper-V environment. If you want to take a look at what counters are being collected by the Capacity Planning solution, you can export the following MPs from your OpsMgr management group and take a look using MPViewer.

The OpsLogix Capacity Report MP provides a set of generic reports that can be used to forecast pretty much any existing counters that are being currently collected in your OpsMgr environment. This is purely a reporting MP, it does not collect any performance counters by itself.

Since the performance data collected by the OMS Capacity Planning solution is being saved only at your OMS workspace, you will not see these performance collection rules from the drop down lists in the OpsLogix capacity reports because they are not available in your OpsMgr Data Warehouse DB.

Although I have not personally tried it, theoretically, you can use the OpsLogix capacity report MP to produce forecasting reports for your Hyper-V environments (just like what the OMS Capacity Planning does), as long as you have configured OpsMgr to collect the same counters. Additionally, if you are using other hypervisors such as VMware and they are being monitored by OpsMgr, you can also use the OpsLogix capacity report MP for forecasting your fabric resource utilisation – this is something the OMS Capacity Planning solution does not provide.

Conclusion

I hope I have provided a high level overview and comparison between OMS Capacity Planning solution and OpsLogix Capacity Report MP in this post. If you have questions or feedback, please feel free to contact me.

  1. Great breakdown. When looking at capacity planning tools, it’s vital to understand the predictive engine behind the tool. Is it using past data + simple trending? If so, then you’re not going to get a reliable forecast, because We discuss the different types of capacity planning tools and approaches to modeling future work loads in our article here: http://www.teamquest.com/en/resources/resource_center/articles/how-choose-capacity-planning-tool/

  2. Great article. A while ago we wrote an article that compared simple forecasting vs advanced forecasting with Operations Manager. As TeamQuest suggest it’s really important to choose the right tool.

  3. The right tool is certainly important and even more so when you consider the price tag of some vendors. The technology behind the predictive engine also matters, but for companies that want basic forecasting, too many bells and whistles are going to distract them from what they really want: A good ballpark figure for when their systems are going to be at capacity.
