Summary


Business-related metrics can provide helpful insights into the enterprise application. These metrics are a part of the business use case and therefore should be treated as such. Business metrics are ultimately impacted by other, technical metrics. It's therefore advisable to monitor these metrics as well.

The theory of constraints describes that there will be one ore more limiting constraints that prevent the system from infinitely increasing its throughput. In order to improve the application's performance the limiting constraint therefore needs to be eradicated. jPDM helps identifying the limiting constraints by finding the dominating consumer of the CPU first and using appropriate tooling to further investigate performance issues. It's advisable to investigate potential bottlenecks by following this process, which takes the overall situation into account, rather than to blindly peek and poke.

Rather than using high-frequency monitoring, engineers are advised to sample technical...
