Every wondered how often your site gets scanned?

I run a demo instance of Atomic Lab’s Pion at home that I use for customer demonstrations and generally playing around.

I have been looking recently at the visitor session replay functionality and it’s fascinating to see how many people are out there just randomly scanning for vulnerabilities.

If we drill down into the headers we can see that in many cases the requests have spoofed headers, IP addresses etc

GET http://www.eduju.com/proxyheader.php HTTP/1.1
Host: www.eduju.com
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)
Accept: */*
Accept-Language: zh-cn
Connection: Keep-Alive

The other common request string appears to be:

GET http://58.218.199.147:7182/judge.php HTTP/1.1

All of these requests use up your server resources, but standard analytics won’t show them up, so network-level analytics like Pion are the way to go!

Alexa has performance rankings too!

I must confess that this one had slipped past me… I wasn’t aware that Alexa was now offering performance rankings as well! Alexa now shows an “average load time” as well as a “comparitive ranking” (i.e. 51% of sites are slower). Interesting data for your next website analysis! It’s worth noting that the quoted “1.404 seconds” is about the same as the “repeat view” measurement webpagetest.org (testing from the UK node shows that www.johnlewis.com takes about 7.2 seconds to load with an empty cache, and 1.6 seconds with a primed cache, median values over 5 runs). Presumably this is an average across all Alexa toolbar users, on all johnlewis.com pages (large and small) with empty and primed caches.

Load Testing Case Study

Since we are talking about presentations here is another one I did for the Load Testing Expo in 2009. It’s a case study of how we did the performance testing for an internet-facing content/community/jobs site.

Real-time Web Analytics just took a step forward with Pion v4

Awesome news from Atomic Lab’s that Pion 4.0 has been released! The new Dashboard functionality looks amazing – real-time web analytics likes page views, visitor sessions etc as well as performance analytics like load time and server reply time – along with the usual Pion goodness like tag-free analytics and customer journey visualisation with the Replay feature. Can’t wait to implement this on some customer sites!
