Drift is the unplanned or unintended changes that occur on a resource’s configuration. System administrators need the ability to track drift in their data centers to improve availability and reliability of their platforms, servers and applications.
Drift monitoring is a new feature in the latest version of the JBoss Operations Network 3.0 (JON). You can define a drift detection definition on the Drift page of a resource. Click the New button, assign your drift definition a name, a base directory, then select the files and/or folders to be monitored for drift. Wait a few minutes and JON will take the initial snapshot (snapshot 0) of your monitored files. Each time drift is detected, JON takes a new snapshot of the monitored files. Each snapshot has a number, and snapshots can be viewed in an intuitive, new view known as the snapshot carousel by double-clicking on the drift definition from the Drift page of the resource.

As technology consultants, we’re typically brought in by a customer to help them get somewhere specific they can’t reach on their own because of resources, skills, time or a host of other reasons. One of the things I’m most surprised by during these engagements, however, is how many IT organizations know where they want to go, but they don’t necessarily know where they are, or swear they are somewhere else. The knowledge they have about their infrastructure and what’s going on in their datacenter right now is extremely limited, or at best stale due to a lack of realtime data.
The value of understanding where you are today is immense, and is an important first step in realizing your IT goals and to help you move towards your ideal datacenter. Knowing where you stand and having a clear map of your current environment shines a light on opportunities to become leaner, to improve performance and automation, and to drive efficiency. The benchmarks you’ll create will help you conduct TCO/ROI calculations that actually mean something, so it will be clear how to become more agile, and become more responsive to the business.
