To ensure such performance, you need a sound IT infrastructure. And data that informs you about historic performance as well as what’s happening right now is the foundation for planning and managing a well-functioning IT system.
Monitor Around the Clock
Corporate security oversees a company’s grounds and buildings 24/7/365. If someone entered the building who should not have been there, they could review security tapes to see how it happened and who it was. If there’s a real-time threat, they can spot it on their cameras and take action to prevent escalation immediately.
You need the same level of oversight for your IT environment. The data enables you to both predict and prevent slowdowns and downtime as well as dig into the past to determine the cause of an issue.
You need to be able to avoid skewed views that can occur as the result of an exceptional single data point or edge case. Otherwise, averages will hide these anomalies. To present an accurate, realistic picture, you need to be able to eliminate such outliers. To do this, create a high degree of granularity by collecting data every five minutes or so. It will enable you to detect extreme spikes and dips and remove them.
While you want to be granular in your timing, you need to be broad in your scope. By nature, IT infrastructures are connected. So you need to monitor all brands of servers, storage, and SAN as well as applications with one tool that encompasses your on-premise and cloud technology, giving you the big picture.
Keep Historical Data
The past provides perspective. By looking at changes in your data from two or three years ago to today, you can plan better for future technology.
There is, however, a catch. Keeping data forever could put a strain on one of your servers, which could cause poor performance—the exact issue you’re trying to prevent. The solution is to keep this data in the cloud where resources can expand elastically to accommodate it.
Use Predictive Analytics
Many tools provide alerts. They’re like the security alarm that goes off when someone has broken into a house. Yes, they allow you to take action, but it may be too late to prevent the robbery.
Rather than alerts, you’re better off with a dashboard that provides analytic thresholds for servers, storage, and SAN, showing you whether you need to take action to avert problems in any area. They tell you whether the CPU is busy, and indicate the network adaptor throughput, disk service times and more.
To make it as easy as possible, thresholds should be color coded. For example, green means ‘everything is running fine.’ Yellow means ‘you need to address this,’ otherwise, for instance, your CPU will be pegged in ten days. And red flags you that ‘you’ve waited too long; users are now experiencing poor service.’ (You’ll only see red if you’re not paying attention to your monitoring tool.) Used correctly, this information, allows you to address potential problems before they affect users.
So keep employees and customers happy with responsive applications by ensuring a sound IT infrastructure. The key to this is to have a tool that monitors with granularity around the clock, does so across your entire IT infrastructure, maintains historical data for as long as you like, and provides predictive analytics to help you use the data successfully.
