Web application up-time is critical to any organization. Regardless of the applications being accessed from inside or outside the firewall, they need to be up and running all the time. So, it is critical to proactively monitor the availability and response time from one or more locations at all times, and isolate issues before your users do.
So, how do you do that? With the right monitoring software in place to:
- Test Web app performance after a change is made
- Determine when Website performance is trending poorly
- Pinpoint Web app performance bottlenecks
It’s also imperative to monitor the availability and responsiveness of websites and Web applications from inside the firewall or external-facing applications from multiple locations.
Finding the Root Cause of a Slow Transaction
Let’s take the example of a website that’s experiencing delays or is slow to load or respond. How do we find the source of this issue?
Step 1: You need to be able to receive real-time alerts on website response time. Set up a high-level alert like:
- Web page is not loading
- Website transaction has failed
- Slow response time
Then you can drill down to find more specific conditions that triggered the alert. Alerts tell you there is a problem.
Step 2: Compare the scenario of the alert with predefined baseline performance.
For successful website monitoring, you should first define baseline performance metrics so that when there’s a problem, you can compare poor performance against the baseline to gauge severity and isolate the fault. Use baseline metrics to locate the problem.
Step 3: Look at historical performance of the Web page to identify which of the page elements – HTML, script, images, CSS, etc. – have deviation from the standard performance. Analyzing the individual page elements and identifying the one causing the delay will give you the source or root cause of your issue. Analyze historical performance to identify the source of the issue.
The buck doesn’t stop here. You also need to test the effects of changes to your website from the end-user’s perspective, as well as from multiple locations. This will let you measure performance as experienced by end-users in different locations.
