Top Seven Website Performance Indicators to Monitor

Whatever the reason for a website crashing or slowing down, it’s bad for business and for your online reputation

Poorly performing websites, like Twitter's recent fiasco with Ellen's selfie, are a constant source of irritation for users. At first you think it's your computer, or maybe someone on your block is downloading the entire "Game of Thrones" series. But, when nothing changes after refreshing the page once or twice, you give up, mutter under your breath, and move on.

Whatever the reason for a website crashing or slowing down, it's bad for business and for your online reputation. According to a survey conducted by Consumer Affairs, a dissatisfied customer will tell between 9-15 people about their experience. And, if your website can't load fast enough (in 400 milliseconds), then most of your customers will search for another website.

Understanding how your website performs under pressure is extremely important for any company. But, it can be daunting trying to figure out what website performance indicators you should monitor.

We have compiled a list of the top seven website performance indicators we believe to be important. Make sure to track each of these to guarantee a great customer experience.

Top Seven Website Performance Indicators

1. Uptime
Monitoring the availability of your website is without a doubt the single most important part of website monitoring. Ideally, you should constantly check the uptime of your key pages from different locations around the world. Measure how many minutes your site is down over a period of two weeks or a month, and then express that as a percentage.

2. Initial Page Speed
Consumers' behavior and tolerance thresholds have changed. Now, people who browse a website expect it to load in a blink of an eye. If it doesn't load quickly, they will leave and turn to a competitor's site. You can check your website's speed using Ping requests (measuring the time it takes from your location until the website starts loading) and loading time measurements, for example, measuring the time it takes to download the source code of a web page. Note that this measurement reflects the time it takes for the raw page to load, but that isn't the complete user experience. For that, you must measure...

3. Full Page Load Time including images, videos, etc.
This performance indicator is usually called End User Experience testing. It's the amount of time it takes for all the images, videos, dynamically-loaded (AJAX) content, and everything else seen by the user to pop up on the their screen. This is different than the time it takes for the raw file to download to the device it's going to display on (as indicated above).

Both full page load time and page speed are important to measure because you can employ different strategies to optimize for both of them. Images, videos, and other static content can be cached on separate, dedicated systems or content delivery networks (CDNs), while dynamic content might need dedicated servers and fast databases. Knowing how your website behaves as it scales will help you put the right infrastructure in place.

4. Geographic Performance
If you are a globally active company or if you have consumers from different parts of the world, understanding your geographical performance - which is your website's speed and availability in different locations - is extremely important. Your ultimate goal is to make sure your website is easily accessible to all visitors regardless of their location to give them an excellent customer experience.

Many companies ignore this factor, only testing performance in familiar geographies. At a minimum, use your website analytics as a guide to put testing in place that shadows the locations from which your visitors are accessing your site.

5. Website Load Tolerance
Do you know how many visitors it takes to considerably slow down your website? It's an important indicator to understand because if you are running aggressive marketing campaigns or are picked up by the press you might be in a situation where your website is flooded with visitors in a matter of minutes.

Regularly run stress tests and compare the results to your visitor numbers at peak times. Once you understand how much load your website can handle then you can adjust your infrastructure to meet the demand. Look for those "tipping points" so you won't be caught by surprised when traffic spikes.

6. Web Server CPU Load
CPU usage is a common culprit in website failures. Too much processing bogs down absolutely everything on the server without much indication as to where the problem lies. You can prevent web server failures by monitoring CPU usage regularly. If you cannot install monitoring software on your web servers due to hosting arrangements or other constraints, consider running a script that publishes the values from available disk space and CPU load to a very simple html page.

7. Website Database Performance
Your database can be one of the most problematic parts of your website. A poorly optimized query, for example, can be the difference between a zippy site and an unusable one. It's important to monitor your database logs closely. Create alerts if the results contain certain error messages, or deliver results outside of expected norms. Use the built-in capabilities of the database to see which queries are taking the most time, and identify ways to optimize those through indices and other techniques. Most importantly, monitor the overall performance of the database to make sure it's not a bottleneck.

No Downtime = Happy Customers
If you can monitor all seven of these metrics, you should have a good idea of how your website performs and what needs to change when it doesn't perform well. Minimizing website downtime will keep your customers happy. If you have any questions on these metrics or load testing let me know.

The Internet of Things (IoT) is growing rapidly by extending current technologies, products and networks. By 2020, Cisco estimates there will be 50 billion connected devices. Gartner has forecast revenues of over $300 billion, just to IoT suppliers. Now is the time to figure out how you’ll make money – not just create innovative products. With hundreds of new products and companies jumping into the IoT fray every month, there’s no shortage of innovation. Despite this, McKinsey/VisionMobile data shows "less than 10 percent of IoT developers are making enough to support a reasonably sized team....
Just over a week ago I received a long and loud sustained applause for a presentation I delivered at this year’s Cloud Expo in Santa Clara. I was extremely pleased with the turnout and had some very good conversations with many of the attendees. Over the next few days I had many more meaningful conversations and was not only happy with the results but also learned a few new things. Here is everything I learned in those three days distilled into three short points.
DevOps is about increasing efficiency, but nothing is more inefficient than building the same application twice.

We all know that data growth is exploding and storage budgets are shrinking. Instead of showing you charts on about how much data there is, in his General Session at 17th Cloud Expo, Scott Cleland, Senior Director of Product Marketing at HGST, showed how to capture all of your data in one place. After you have your data under control, you can then analyze it in one place, saving time and resources.
With all the incredible momentum behind the Internet of Things (IoT) industry, it is easy to forget that not a single CEO wakes up and wonders if “my IoT is broken.” What they wonder is if they are making the right decisions to do all they can to increase revenue, decrease costs, and improve customer experience – effectively the same challenges they have always had in growing their business. The exciting thing about the IoT industry is now these decisions can be better, faster, and smarter. Now all corporate assets – people, objects, and spaces – can share information about themselves and thei...
The cloud. Like a comic book superhero, there seems to be no problem it can’t fix or cost it can’t slash. Yet making the transition is not always easy and production environments are still largely on premise. Taking some practical and sensible steps to reduce risk can also help provide a basis for a successful cloud transition. A plethora of surveys from the likes of IDG and Gartner show that more than 70 percent of enterprises have deployed at least one or more cloud application or workload. Yet a closer inspection at the data reveals less than half of these cloud projects involve production...

Discussions of cloud computing have evolved in recent years from a focus on specific types of cloud, to a world of hybrid cloud, and to a world dominated by the APIs that make today's multi-cloud environments and hybrid clouds possible. In this Power Panel at 17th Cloud Expo, moderated by Conference Chair Roger Strukhoff, panelists addressed the importance of customers being able to use the specific technologies they need, through environments and ecosystems that expose their APIs to make true change and transformation possible.
Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem" in this scenario: microservice A (releases daily) depends on a couple of additions to backend B (re...
The Internet of Things is clearly many things: data collection and analytics, wearables, Smart Grids and Smart Cities, the Industrial Internet, and more.
