The modern world abounds with rumors of unbelievable things. Was it really Bigfoot getting a drink at the local coffee house this morning? Well, we all do need that first cup. And IT is no stranger to mythical creatures. Possibly one of the biggest to hit data center operations is the single pane of glass.
Single pane of glass is a term for a unified IT operations dashboard designed to bring relief to IT personnel who have suffered with multiple management and monitoring tools, browser incompatibilities, Java version issues and a host of other problems, while simply trying to troubleshoot issues in day-to-day IT operations.
This hasn't gone unnoticed from management and monitoring tool vendors. Many of them have made the transition from thick clients hosted on site to web-based tools that support more OS platforms. However, the overall success of an IT operations dashboard is somewhat questionable. While thick clients removed the reliance on specific software, many found that the web-based tools had features that required specific plug-ins, Flash or Java versions. This idea of wide compatibility exploded -- and so did the person's temper who found that tools failed to function after a web browser update.
In an ideal world, the IT operations staff would have one dashboard to monitor and adjust systems throughout the data center. This would cut down on training, reaction time and confusion for IT staff, leading to better service to end users. This is the true goal of the single pane of glass.
One of the challenges to a single-pane IT operations dashboard is that no single vendor makes all the tools in a modern data center. IT shops typically acquire vendors' products to meet business needs, within the constraints of IT budgets. While this diversity is great for the business, it creates challenges for the staff required to deploy and support these technology stacks. IT staff must already be experts on multiple environments, now they must adjust as those interfaces change with each and every update. Even with products that promise integrated management, such as hyper-converged infrastructure, IT ops still has external networking gear and the guest operating systems to contend with -- but more on that later.
Hyper-converged infrastructure is realizing the ideal of integrated monitoring and management up and down the technology stack. Since previously unique data center silos -- compute, storage, virtualization and management -- go into the same box, the tools they come with are better for both the monitoring and execution of tasks. This still does not include all the external data center pieces that the HCI environment interfaces with, but it is a start for a unified IT operations dashboard.
While this all sounds bleak, there is a little light at the end of the tunnel, and the odds are only 50-50 that it's a train.
Less pain to integrate
Many IT management and monitoring tools have adopted application programming interfaces (APIs) that allow other products to interface with the systems and, in many cases, enact two-way communications. This can amount to an integration as simple as pulling alerts, data and performance stats into a dashboard, or as complex as executing scripts and performing operational functions.
APIs show a glimmer of the all-encompassing IT operations dashboard promise. However, all vendors prefer for their customers to use the tools natively provided, sometimes at an additional cost. Vendors put a lot of resources into making these tools, which makes it difficult to put effort into the best set of APIs to let their product be subsumed into an IT operations dashboard with competing or unaffiliated products. This can leave the third-party experience a bit questionable, creating a less-than-ideal situation for the user in the data center.
So while that single pane of glass does exist, it's not the magic mirror for which you were hoping. Different companies have options that piggy back on their own IT operations technology, while others interface into a wide range of products, but the result is still a subpar dashboard experience.
Don't give up on the idea of a controlling mega-IT operations dashboard now that you see its limitations. Collecting data is always easier than executing commands within a single pane of glass-type dashboard. This means it is possible to have a decent single view into IT operations, even if you still must go into varied tools and dashboards to manage it. It's not ideal, but it's a start.
Any single pane of glass for IT monitoring must also include the application that the technology stack supports. Application monitoring isn't top of mind for IT operations pros, but it is the most critical and customer-visible part of the entire IT deployment.
