The AppD Approach: Leveraging Docker Store Images with Built-In AppDynamics

In my previous blog we explored some of the best and worst practices of Docker, taking a hands-on approach to refactoring an application, always with containers and monitoring in mind. In that project, we chose to use physical agents from the Appdynamics download site as our monitoring method. But this time we are going to […]

The AppD Approach: Composing Docker Containers for Monitoring

Since its introduction four years ago, Docker has vastly changed how modern applications and services are built. But while the benefits of microservices are well documented, the bad habits aren’t. Case in point: As people began porting more of their monolithic applications to containers, Dockerfiles ended up becoming bloated, defeating the original purpose of containers. […]

Tales from the Field: Migrating from Log4J to Log4J2

The AppDynamics Java agent, like many Java applications, uses logging extensively. We have used Log4J as our logging framework for many years. And while the latest release of Log4J was in 2012 – and the Apache Foundation announced end-of-life for Log4J in August 2015 – we didn’t upgrade to Log4J2 because of the need to […]
