Some developers believe that monitoring is a function of operations team. Some operations teams firmly believe that monitoring the systems they maintain is sufficient to run the business successfully. Most of them are wrong. The complexity of today’s applications have gone far and beyond the capabilities of “traditional” system-level monitoring tools and approaches and requires much broader knowledge of business and application as a whole. The goal of DevOps is to connect all aspects of application development and operations, and monitoring provides visibility and troubleshooting tools to accomplish that goal.
This talk is intended to provide real-world examples of common gaps in monitoring approach and explain why holistic instrumentation of business and functionality monitors should be a part of any project scope.
