When we think of application performance problems that are network-related, we often immediately think of bandwidth and congestion as likely culprits; faster speeds and less traffic will solve everything, right? This is reminiscent of recent ISP wars; which is better, DSL or cable mode...
In a previous post, we discussed why GoDaddy could sustain the peak load after its Super Bowl Ad campaign aired and why others like Kia wasted a lot of marketing money because its site availability dropped under the load. In this post, we will look at the technical details behind the i...

At times, I can be a bit of a procrastinator. If there is no pressing need to clean out the garage this week, shop for holiday gifts, or do my taxes, I can easily be convinced to let it go until next week or next month. Inevitably, though, something happens that makes me wish I hadn’t ...
The argument that system monitoring is just a nice to have, and not really a core requirement for operational readiness, dissipates quickly when a critical application goes down with no warning. Can event management help foster a curiosity for innovative possibilities to make applicat...
Recently, one of our customers, let’s call him PointInFact, had a very typical problem. After deploying a new version of its software, some user requests degraded horribly. Requests that should have taken half a second took up to a minute. Interestingly, the PointInFact team runs a mul...
By embracing End-User-Experience (EUE) measurements as a key vehicle for demonstrating productivity, you build trust with your constituents in a very tangible way. The translation of IT metrics into business meaning (value) is what APM is all about. The goal here is to simplify a comp...
There has been a lot of talk among vendors and industry experts in the last year about how APM fits in with the DevOps philosophy. There have been many claims that because a vendor is easy to install and use, it automatically make it a solution catered for a DevOps crowd. This can’t be...
Today I want to share a success story from one of our customers in the financial business that combined the currently hyped topic Real User Monitoring with the good old mainframe. They used Real User Monitoring to identify unnecessary calls from their rich client application into the m...
Does your Ops team care about the number of Exceptions thrown in the application – do they even monitor this number? Does your Test Team report the list of Exceptions thrown during a load test to engineering or are they just sending those that end up in a logfile? Is development intere...
Victor Cruz has actually touched on a few interesting points in his article “Safe Driving in the Cloud: A Black Box for Cars”. The fact is that car companies have lately shifted their focus towards increasing security for passengers and drivers altogether and that is why they came up ...
