Detecting Bad Deployments on Resource Impact & Not Response Time This story came in from Joseph - one of our fellow dynaTrace users and a performance engineer at a large fleet management service company. Their fleet management software runs on .NET, is developed in-house, is load tested with JMeter and monitored in Production with dynaTrace. A usage and configuration change of their dependency injection library turned out to dramatically impact CPU and memory usage while not yet impacting end user experience. Lessons learned: resource usage monitoring is as important as response time and throughput. On Wednesday, July 3, Joseph's ops team deployed the latest version into their production environment. Load (=throughput) and response time are two key application health measures the application owner team has on their production dashboards. Especially after a new deplo... (more)

Web Service Monitoring 101: Identifying Bad Deployments

Have you ever deployed a change to production and thought "All went well - Systems are operating as expected!" but then you had to deal with users complaining that they keep running into errors? When deployments fail you don't want your users to be the first to tell you about it: Sit down with the Business and Dev to define how and what to monitor We recently moved some of our systems between two of our data centers - even moving some components to the public cloud. Everything was prepared well, system monitoring was set up and everyone gave the thumbs up to execute the move. ... (more)

Choosing the APM System that Is Right for You

In my role as technology evangelist I spend a lot of time helping organizations, big and small, make their IT systems better, faster and more resilient to faults in order to support their business operations and objectives. I always find it frustrating to "argue" with our competitors about what the best solution is. I honestly think that many APM tools on the market do a good job - each with advantages and disadvantages in certain use cases. There is no "one size fits all" - there is just a "this tool fits best for your APM Maturity Level" (not saying the others wouldn't do a goo... (more)
