In Part I of this blog I explained which metrics on the Web Server, App Server and Host allow me to figure out how healthy the system and application environment is: Busy vs. Idle Threads, Throughput, CPU, Memory, etc.
In Part 2, I focus on the set of metrics captured from within the application server (#Exceptions, Errors, etc.) as well as the interaction with the database (connection pools, roundtrips to database, amount of data loaded, etc.). Most of the screenshots shown in this blog comes from real performance data shared from our Dynatrace Free Trial users that leveraged my Share Your PurePath program where I helped them analyze the data they captured. I also hope you comment on this blog and share your metrics with the larger performance testing community.
