The simplest of changes to your virtual environment can have a profound impact. Even launching a single VM can release a bevy of evil Change Gremlins that can take down your entire system.
How can you be prepared for those villainous Change Gremlins? Perhaps they have already wreaked havoc or started a chain reaction of consequences. Don’t wait to get a stream of calls and helpdesk tickets from unhappy users. Your favorite super hero is here to save the day: Dell Foglight Change Analyzer!
Not only will the mighty Change Analyzer protect you from those feisty Change Gremlins, but she offers guidance to help you think ahead and anticipate how certain changes might affect your environment. Change Analyzer recommends that you first follow these four basic steps to keep the Change Gremlins away and get the best performance out of your virtual environment:
It’s important to have a change management protocol in place. Manually tracking and documenting changes and their impact can be a stop-gap, but as your virtual environment grows, so does the difficulty of change management as well as the margin for human error. When your IT staff is busy putting out fires, they don’t always have time to document every detail, even if that is part of the protocol. And that’s when the Change Gremlins can sneak in.
At times like these, virtual performance management super heroes … er, software … can be invaluable. Tools specifically designed for change management, such as Dell Foglight Change Analyzer, help you not only monitor changes once they’ve occurred, but they can even help you measure the potential impact of every change you want to make before you deploy. Over time, you can more proactively predict the impact of commonly taken actions using your own historical data.
This becomes quite easy with the help of Change Analyzer and her amazing dashboards:
Foglight Change Analyzer tracks helps you track changes in your virtual environment, understand their potential impact on performance and availability — and keep the Change Gremlins at bay! She is able to capture and report changes to VMs, hosts, clusters, data stores and resource pools in a single bound — or within a selected environment. She scales to compare VMs to a “gold standard” VM or template and leaps to alert you when changes cause their configurations to drift from the standard.
Change Analyzer is ready to help fight the Change Gremlins any time day or night. (Meaning, the software comes pre-installed and enabled with the latest version of Foglight for Virtualization, Enterprise Edition - and it can also be installed on certain Foglight Management Server versions.)
