Catchpoint Domain Override

In my previous blog A/B testing on CDN improvement we shared how to use A/B test to demonstrate the webpage performance brought by CDN. No matter what tool we used, it required customers to change their webpages to insert some JavaScript codes.

What if our goal is to minimize customer changes during the demonstration/proof of concept stage? I am going to demonstrate Catchpoint performance measurement service to achieve this goal.

Well, let’s take one step further to avoid ANY customer changes!

Catchpoint is one of the popular performance monitoring services. Many enterprises and cloud service providers buy Catchpoint solutions to monitor their websites and Internet services.

One cool Catchpoint feature is domain sharding/override. When it does page load test, Catchpoint can be configured to change the hostnames, say from A to B, in the HTML codes. By doing so Catchpoint will GET the HTTP objects from host…

Use color to add value to your Performance charts. Red and green columns overlay your line chart where red equals an “increase in Response time from previous interval” and green equals “decrease in Response time from previous interval”.

The following excel waterfall chart has the aforementioned conditions applied (red equals an “increase in Response time from previous interval” and green equals “decrease in Response time from previous interval”). In this case, the waterfall chart is showing week-over-week Response time for a landing page. Credit to peltiertech.com for the waterfall template; my additional formatting has been applied.

Suppose you’re an academic site, perhaps a Search Engine or a Reference site. You might theorize the September change in Response time is impact from everyone going ‘back to school’. To further your theory, notice the December change, when everyone is ‘home for the holidays’. What else might you look for? Maybe three ‘reds in a row’, to spot a trend?

Welcome to The Web Tortoise and Hare‘s inaugural post. If you are a Catchpoint, Keynote, Gomez or etc user, then this is for you!

Here will be discussed various web availability, performance and “plus plus” topics. Will slant toward using excel to get additional value from the data provided by companies like Catchpoint, Keynote and Gomez.

Availability: Did you get a response from the server?

Performance: After the response, how long did it take for your web page to load?

“Plus Plus”: Could the time of day have affected the web page load? What other factors might influence either availability or performance? Geography? Ad Serving? Else?

I work for a large internet company [at the time of this inaugural post] whose pages receive several visits each month. I use tools like [those provided by] Catchpoint and Keynote to monitor availability and measure performance. I don’t work for any of those companies and I don’t have anything to sell.
