Open Source Web Site Performance Tools

Louis St-Amour wrote a very helpful comment on my “The Complete List of End-User Experience Monitoring Tools” post – helpful enough that I thought it deserved a whole post. OWA, indeed commonly means Outlook, so it’s kind of unfortunate naming clash, but in this case I’m referring to Open Web Analytics from http://www.openwebanalytics.com/ which has what it calls, “domstream recording”. This lets you see exactly what a user sees in their browser and where their mouse goes, though I’m not sure how embedded it is for performance timing or error catching. A similar feature is...

Applying APM in a Big Data World (Part 2)

In part one of my look at applying application performance monitoring in a big data environment, we examined how nonrelational databases work and what unique challenges they present to traditional application performance monitoring tools. Because of their non-ACID approach, I argued, application performance metrics become very complex in a system where the business transaction itself has a expected non-zero but small probability of failing. So how can you apply APM in a big data world? The first part of the problem is applying the right kind of tool. By their nature, big data environments...

Applying APM in a Big Data World (Part 1)

A recent conference for open source software developers included a full fledged subconference that dealt primarily with the issues of big data: OSCON Data. And no wonder–the process of dealing with millions and billions of data records is performed by mostly open source software tools. Big data is an inevitable outgrowth of Software as a Service (SaaS). As more and more SaaS services are launched, the data being exchanged expands exponentially. A February IDC report, “The Big Deal About Big Data,” estimates that data use in the next decade will amount to 35.2 zettabytes....

Application Performance Management is a Big Business Getting Bigger

If you doubt that application performance monitoring is gaining traction in the IT world, a recent Software as a Service (SaaS) system management sector ranking should dispel that idea. According to IDC’s “Worldwide System Management Software-as-a-Service 2011-2015 Forecast and 2010 Vendor Shares” report, the application performance monitoring unit of Compuware ranked third behind HP and IBM as an SaaS vendor, with a revenue of $49 million. Application performance monitoring is becoming recognized more and more as an indispensible tool in the IT manager’s toolbelt,...

You Can’t Fix What You Don’t Understand

There’s a great little theatrical bit we see in movies and television: someone starts up a complex machine, the machine falters, then the device gets slapped and works perfectly. Executions of this bit have been done to great comedic effect, such as Han Solo’s punching a console on board the Millennium Falcon in The Empire Strikes Back or the Fonz’s mastery of the jukebox and other machines with a single blow in the 70′s sitcom Happy Days. This sort of thing goes on all the time in real life, too. A big part of our human nature is the (completely wrongheaded) notion...
