Extra resources for APM Best Practices: Realizing Application Performance Management
The investment would include the following: • • • • • • • Assessment of existing skills and capabilities. Pilot of appropriate monitoring technologies. Identification of an initial and follow-on set of candidate applications, leading to an initial solution sizing. Solution sizing and procurement of appropriate hardware. Product licensing and maintenance (annual). Vendor product training. Solution installation (initial deployment). For this business justification, I am really not looking beyond the operational capabilities.
There are a large number of legacy applications and technologies that are not addressed by APM technology and remain excellent candidates for AM. Nothing changes for those applications and resources, but it is important to understand what they are and what their impact may be, if any, on the distributed applications on which APM is focused. In my experience, in order to understand if it is time to move beyond AM, you need to consider just one question: How do you know that availability monitoring has reached its limit of usefulness?
These can generate thousands of metrics. But they have very little utility when it comes to identifying and resolving a performance incident. They are normally configuration-related and static (time invariant), and while a few may vary in real-time, they quickly contribute to overhead and can have a significant expense. Measuring overhead and configuration baselines are discussed in the Practitioner’s Guide. The second major concern is scope. If you only have responsibility to select a solution appropriate for one or a few applications, you really do not have to address the utility of that solution for other applications.
